Present Subjunctive - Regular Verbs
Presente de subjuntivo - Verbos regulares
The subjunctive is a verb mood used to express wishes, doubts, emotions, and recommendations. For regular verbs, you form it by 'swapping the vowel': -ar verbs take -e endings, while -er and -ir verbs take -a endings. So hablar becomes hable, comer becomes coma, and vivir becomes viva. The subjunctive usually appears after 'que' in a subordinate clause, triggered by specific verbs or expressions in the main clause.
Key rule
Swap the vowel: -ar verbs take -e endings, -er/-ir verbs take -a endings, always triggered by a specific expression in the main clause.
Examples
- Quiero que hables con ella.Quiero que hablas con ella.
After 'quiero que' (wish + different subject), the subjunctive is required: hables, not hablas.
- Es importante que estudies cada día.Es importante que estudias cada día.
Impersonal expressions like 'es importante que' trigger the subjunctive: estudies.
- Espero que comas bien.Espero que comes bien.
Esperar que (to hope that) triggers the subjunctive: comas, not comes.
Common mistakes
Using indicative instead of subjunctive after trigger expressions
Quiero que hablas españolQuiero que hables españolAfter 'quiero que' the subjunctive is mandatory because there are two different subjects and a wish is expressed.
Not swapping the vowel correctly
Es necesario que comemos másEs necesario que comamos másFor -er verbs in subjunctive, use -a endings (comamos), not -e endings.
Present Subjunctive - Irregular Verbs
Presente de subjuntivo - Verbos irregulares
Some very common verbs have irregular present subjunctive forms that you must memorize. Key fully irregular forms include sea (ser), haya (haber), vaya (ir), sepa (saber), dé (dar), and esté (estar). Stem-changing verbs also behave specially: -ar and -er stem-changers keep the change in the boot pattern (piense/pensemos), but -ir stem-changers have an additional change in nosotros and vosotros (duerma/durmamos, sienta/sintamos). Mastering these irregulars is essential because they appear constantly in everyday Spanish.
Key rule
Memorize the seven fully irregular subjunctive stems (sea, haya, vaya, sepa, dé, esté, quepa), and remember that -ir stem-changers have an extra change in the nosotros/vosotros forms.
Examples
- Es importante que seas puntual.Es importante que sos puntual.
Ser in subjunctive is completely irregular: sea, seas, sea, seamos, seáis, sean.
- Espero que haya suficiente comida.Espero que ha suficiente comida.
Haber in subjunctive: haya. Used impersonally (there is/are) and as auxiliary.
- No creo que vayan a la fiesta.No creo que van a la fiesta.
Ir in subjunctive: vaya, vayas, vaya, vayamos, vayáis, vayan.
Common mistakes
Using indicative forms of ser instead of subjunctive
Quiero que eres más amableQuiero que seas más amableSer has a fully irregular subjunctive stem: sea, seas, sea, seamos, seáis, sean.
Forgetting the nosotros stem change for -ir verbs
Es importante que duermamos ocho horasEs importante que durmamos ocho horasDormir nosotros subjunctive uses o→u: durmamos. The diphthong ue only appears in the boot forms.
Conditional Tense - Regular Verbs
Condicional simple - Verbos regulares
The conditional tense expresses what 'would' happen. It is formed by adding -ía endings to the full infinitive, just like the future tense uses the full infinitive as its base. The endings are the same for all verb types: -ía, -ías, -ía, -íamos, -íais, -ían. So hablar becomes hablaría, comer becomes comería, and vivir becomes viviría. The conditional is used for polite requests, hypothetical situations, giving advice, and expressing wishes.
Key rule
Add -ía, -ías, -ía, -íamos, -íais, -ían to the full infinitive; the endings are identical for all verb conjugations.
Examples
- Yo hablaría con ella, pero no tengo tiempo.Yo hablaía con ella, pero no tengo tiempo.
Conditional = full infinitive (hablar) + -ía = hablaría.
- ¿Comerías una pizza entera?¿Comerrías una pizza entera?
Conditional of comer: comer + -ías = comerías (one r).
- Ella viviría en París si pudiera.Ella viveía en París si pudiera.
Keep the full infinitive vivir + -ía = viviría.
Common mistakes
Confusing conditional with imperfect endings
Yo hablaba más si pudiera (imperfect instead of conditional)Yo hablaría más si pudieraThe imperfect uses -aba (for -ar) and the conditional uses -ía added to the infinitive. Hablaría = would speak; hablaba = used to speak.
Removing the infinitive ending before adding conditional
Yo comía en ese restaurante (imperfect, not conditional)Yo comería en ese restauranteThe conditional keeps the full infinitive: comer + -ía = comería. Without 'er', comía is the imperfect.
Conditional Tense - Irregular Verbs
Condicional simple - Verbos irregulares
The same twelve verbs that have irregular stems in the future tense use those same irregular stems in the conditional. Instead of using the full infinitive, they use a shortened or modified stem. For example, decir becomes dir- (diría), hacer becomes har- (haría), and poder becomes podr- (podría). The good news is that the endings are the same regular -ía endings. If you already know the irregular future stems, you know the irregular conditional stems too.
Key rule
The same 12 verbs with irregular future stems use those stems in the conditional too, with regular -ía endings: diría, haría, podría, pondría, querría, sabría, saldría, tendría, vendría, habría, cabría, valdría.
Examples
- Yo diría que es una buena idea.Yo deciría que es una buena idea.
Decir conditional: irregular stem dir- + -ía = diría, not deciría.
- ¿Qué haría usted en mi lugar?¿Qué hacería usted en mi lugar?
Hacer conditional: irregular stem har- + -ía = haría, not hacería.
- ¿Podrías ayudarme?¿Poderías ayudarme?
Poder conditional: irregular stem podr- + -ías = podrías.
Common mistakes
Using the full infinitive instead of the irregular stem
Yo hacería la tareaYo haría la tareaHacer uses the irregular stem har-, not the full infinitive hacer-. The conditional is haría.
Inventing irregular stems that don't exist
Yo ponería la mesaYo pondría la mesaPoner uses pondr- (with a -d- inserted), not poner- minus -er. The pattern is: pon-d-r-ía.
Pluperfect Tense
Pretérito pluscuamperfecto
The pluperfect tense describes an action that had been completed before another past action. It is formed with the imperfect of haber (había, habías, había, habíamos, habíais, habían) plus a past participle. For example, 'Cuando llegué, ya habían comido' means 'When I arrived, they had already eaten.' Think of it as the past of the past. It always uses había, never hube.
Key rule
Había + past participle expresses actions completed before another past action; always use había (never hube) and the participle never changes.
Examples
- Cuando llegué, ya habían comido.Cuando llegué, ya hubieron comido.
The pluperfect always uses había/habían, never the preterite hube/hubieron.
- Ella ya había salido cuando la llamé.Ella ya había salida cuando la llamé.
With haber, the participle never agrees: había salido (not salida), regardless of subject.
- Nunca antes habíamos visitado España.Nunca antes hemos visitado España. (present perfect instead)
For 'before a past point', use pluperfect habíamos visitado, not present perfect hemos visitado.
Common mistakes
Using preterite of haber instead of imperfect
Cuando llegué, hube comidoCuando llegué, había comidoThe pluperfect always uses the imperfect of haber (había). The preterite anterior (hube + participle) is virtually extinct in modern Spanish.
Making the participle agree with the subject
Ella había salida de casaElla había salido de casaWhen used with haber, the participle is invariable. It never agrees in gender or number.
Future Perfect Tense
Futuro perfecto
The future perfect is formed with habré + past participle. It expresses actions that will have been completed by a future point in time: 'Para las cinco, habré terminado' means 'By five, I will have finished.' It is also commonly used to speculate about what probably happened in the past: 'Habrá llegado ya' means 'He must have arrived by now.' This speculative use is very common in everyday Spanish.
Key rule
Habré/habrás/habrá/habremos/habréis/habrán + past participle for completed future actions or speculation about the past.
Examples
- Para las diez, habré terminado.Para las diez, tendré terminado.
Future perfect uses habré + participle, not tendré.
- Cuando llegues, ya habremos comido.Cuando llegas, ya habremos comido.
After 'cuando' referring to the future, use subjunctive (llegues), with the main clause in future perfect.
- Habrá salido temprano hoy.Habrá salida temprano hoy.
Speculation about the past: habrá + salido (invariable participle). He must have left early.
Common mistakes
Using tener instead of haber
Para mañana tendré hecho el trabajoPara mañana habré hecho el trabajoThe future perfect is always formed with haber (habré), not tener. 'Tener + participle' is a different construction emphasizing result.
Making the participle agree with the subject
Ellas habrán terminadasEllas habrán terminadoWith haber, the participle never changes form, regardless of the subject's gender or number.
Past Progressive
Pasado progresivo (estaba + gerundio)
The past progressive uses estaba + gerund (-ando/-iendo) to describe actions that were in progress at a specific moment in the past. It is very similar to the English 'was doing.' For example, 'Estaba estudiando cuando llamaste' means 'I was studying when you called.' It emphasizes the ongoing nature of the past action more than the simple imperfect does.
Key rule
Estaba + gerund (-ando/-iendo) describes actions that were actively in progress at a past moment, often interrupted by another event.
Examples
- Estaba estudiando cuando llamaste.Estuve estudiando cuando llamaste.
For an ongoing action interrupted by another, use the imperfect estaba, not the preterite estuve.
- Los niños estaban jugando en el parque.Los niños estaban jugaban en el parque.
Use the gerund (jugando) after estaban, not a conjugated verb (jugaban).
- ¿Qué estabas haciendo a las tres?¿Qué estabas hiciste a las tres?
After estabas, use the gerund haciendo, not the preterite hiciste.
Common mistakes
Using preterite of estar instead of imperfect
Estuve cocinando cuando llegasteEstaba cocinando cuando llegasteFor an action in progress at a past moment (especially when interrupted), use estaba (imperfect), not estuve (preterite). Estuve + gerund emphasizes duration/completion.
Using a conjugated verb instead of gerund
Estaba comía en ese momentoEstaba comiendo en ese momentoAfter estar, always use the gerund (-ando/-iendo), never a conjugated verb form.
Gerund vs. Infinitive Usage
Gerundio vs. infinitivo
In Spanish, the infinitive is used in many places where English uses the -ing form. As a subject, use the infinitive: 'Estudiar es importante' (Studying is important), not 'Estudiando es importante.' After prepositions, use the infinitive: 'antes de comer' (before eating), not 'antes de comiendo.' The gerund (-ando/-iendo) is only used for actions that are currently in progress, typically with estar or to describe how something is done.
Key rule
Use the infinitive (not gerund) as a subject and after prepositions; the gerund is only for ongoing actions with estar or describing manner.
Examples
- Estudiar es importante.Estudiando es importante.
As a sentence subject, use the infinitive (estudiar), not the gerund (estudiando).
- Antes de comer, lávate las manos.Antes de comiendo, lávate las manos.
After prepositions (antes de), always use the infinitive: comer.
- Sin decir nada, se fue.Sin diciendo nada, se fue.
After the preposition 'sin', use the infinitive: decir, not the gerund diciendo.
Common mistakes
Using gerund as subject (English interference)
Nadando es buen ejercicioNadar es buen ejercicioIn Spanish, the subject of a sentence must be an infinitive, not a gerund. English uses -ing as subject, but Spanish uses the infinitive.
Using gerund after prepositions
Después de comiendo, salimosDespués de comer, salimosAfter all prepositions (de, sin, para, antes de, después de, por, al), use the infinitive in Spanish.
Passive 'Se' Construction
Pasiva refleja con 'se'
The 'se' passive is a very common way to express passive meaning in Spanish without naming who does the action. The verb agrees with the logical subject: 'Se habla español' (Spanish is spoken), 'Se venden coches' (Cars are sold). Notice that with a singular noun the verb is singular, and with a plural noun the verb is plural. This construction is different from the impersonal 'se' where the verb is always singular: 'Se come bien aquí' (One eats well here / You eat well here).
Key rule
Se + verb in third person, agreeing with the logical subject: 'Se vende casa' (singular), 'Se venden coches' (plural).
Examples
- Se habla español aquí.Se hablan español aquí.
Español is singular, so the verb is singular: se habla.
- Se venden pisos en esta calle.Se vende pisos en esta calle.
Pisos is plural, so the verb must be plural: se venden.
- Se necesitan profesores de inglés.Se necesita profesores de inglés.
Profesores is plural, so the verb agrees: se necesitan.
Common mistakes
Not making the verb agree with the logical subject
Se vende coches usadosSe venden coches usadosIn passive se, the verb must agree with the logical subject. Coches is plural, so: se venden.
Using plural verb with impersonal se
Aquí se comen muy bienAquí se come muy bienImpersonal se (no specific subject acted upon) always uses singular: se come.
Imperative - Nosotros (Let's)
Imperativo - Nosotros
The nosotros imperative means 'let's do something.' It uses the nosotros form of the present subjunctive: '!Hablemos!' (Let's talk!), '!Comamos!' (Let's eat!), '!Escribamos!' (Let's write!). The one major exception is 'ir': instead of 'vayamos', Spanish uses '!Vamos!' for 'let's go.' When adding pronouns, they attach to the end and the final -s of the verb drops before -nos: 'Sentemos + nos = !Sentémonos!' (Let's sit down!). The negative form uses 'no' + subjunctive: '!No hablemos!'
Key rule
Use the nosotros subjunctive for 'let's' commands; except 'ir' which uses !Vamos! in the affirmative; pronouns attach and the -s drops before -nos.
Examples
- !Hablemos de otra cosa!!Hablemmos de otra cosa!
Nosotros imperative of hablar: hablemos (present subjunctive nosotros).
- !Comamos en ese restaurante!!Comemos en ese restaurante!
Use subjunctive comamos for 'let's eat', not indicative comemos.
- !Vamos al cine!!Vayamos al cine!
For 'let's go', use !Vamos! (exception), not vayamos (which sounds overly formal).
Common mistakes
Using indicative instead of subjunctive for let's
!Comemos juntos!!Comamos juntos!The nosotros imperative uses the subjunctive form: comamos (not indicative comemos).
Using vayamos instead of vamos for let's go
!Vayamos a la playa!!Vamos a la playa!The affirmative 'let's go' uses the special form !Vamos!, not vayamos. However, the negative is 'No vayamos.'
Imperative - Vosotros
Imperativo - Vosotros
The vosotros imperative is used in Spain to give commands to a group of people you address informally. It is formed by replacing the final -r of the infinitive with -d: hablar becomes !hablad!, comer becomes !comed!, vivir becomes !vivid!. For reflexive verbs, the -d drops before -os: sentad + os = !sentaos! (not sentados). The one exception is irse: !idos! The negative uses the subjunctive: !No habléis!, !No comáis!
Key rule
Replace the -r of the infinitive with -d (hablad, comed, vivid); for reflexives, drop the -d before -os (sentaos); the negative uses subjunctive (no habléis).
Examples
- !Hablad más despacio, por favor!!Habláis más despacio, por favor!
Vosotros imperative: replace -r with -d: hablad (not indicative habláis).
- !Comed toda la verdura!!Coméis toda la verdura!
Vosotros imperative of comer: comed.
- !Vivid la vida al máximo!!Vivíd la vida al máximo!
Vosotros imperative of vivir: vivid (no accent needed).
Common mistakes
Using the present indicative instead of imperative
!Coméis la sopa!!Comed la sopa!The imperative drops the -r and adds -d: comed. The indicative coméis is a statement, not a command.
Keeping the -d with reflexive -os
!Sentados en el suelo!!Sentaos en el suelo!The -d drops when -os is added: sentad + os = sentaos. 'Sentados' is the past participle, not the imperative.
Present Perfect Subjunctive
Pretérito perfecto de subjuntivo
The present perfect subjunctive combines haya (subjunctive of haber) with a past participle. It is used after subjunctive triggers when the action has been completed: 'Espero que hayas llegado bien' means 'I hope you have arrived safely.' It is essentially the subjunctive version of the present perfect (he llegado becomes haya llegado). The forms are: haya, hayas, haya, hayamos, hayáis, hayan + past participle.
Key rule
Haya/hayas/haya/hayamos/hayáis/hayan + past participle, used after subjunctive triggers when the action is completed.
Examples
- Espero que hayas llegado bien.Espero que has llegado bien.
After 'espero que', use subjunctive haya: hayas llegado, not indicative has llegado.
- Me alegro de que hayáis venido.Me alegro de que habéis venido.
Emotion (alegrarse de que) triggers subjunctive: hayáis venido.
- Dudo que hayan terminado a tiempo.Dudo que han terminado a tiempo.
Doubt (dudar que) triggers subjunctive: hayan terminado.
Common mistakes
Using indicative present perfect instead of subjunctive
Espero que has terminadoEspero que hayas terminadoAfter subjunctive triggers like 'espero que', haber must be in the subjunctive: haya/hayas/haya, not he/has/ha.
Using present subjunctive when action is completed
Me alegro de que vengas (but they already came)Me alegro de que hayas venidoIf the action is already completed, use the present perfect subjunctive (hayas venido), not the present subjunctive (vengas).
Haber Idioms & Expressions
Expresiones idiomáticas con haber
You already know 'hay' (there is/are), but 'haber' appears in many useful expressions beyond that. 'Hay que + infinitive' means 'one must' or 'it is necessary to,' as in 'Hay que estudiar' (One must study). 'Ha de + infinitive' expresses a softer obligation meaning 'is supposed to.' 'No hay de qué' is a polite way to say 'you're welcome.' Learning these idioms will make your Spanish sound much more natural.
Key rule
Use 'hay que + infinitive' for impersonal obligation (one must), 'ha de + infinitive' for softer personal obligation (is supposed to), and 'no hay de qué' for 'you're welcome.'
Examples
- Hay que practicar todos los días.Ha que practicar todos los días.
The impersonal obligation uses 'hay que,' not 'ha que.' 'Hay' is the impersonal present form of 'haber.'
- No hay de qué, fue un placer.No hay por qué, fue un placer.
'No hay de qué' is the fixed expression meaning 'you're welcome.' 'No hay por qué' is a different expression meaning 'there's no reason to.'
- Has de saber que esto es importante.Has que saber que esto es importante.
'Haber de + infinitive' uses the preposition 'de,' not 'que.' 'Has de saber' means 'you should know.'
Common mistakes
Conjugating 'hay que' for different persons
Yo hay que estudiar.Hay que estudiar. / Tengo que estudiar.'Hay que' is impersonal and does not change for person. For personal obligation, use 'tener que' instead.
Confusing 'hay que' and 'ha de'
Hay de llegar temprano.Ha de llegar temprano. / Hay que llegar temprano.'Hay que' is impersonal obligation. 'Ha de' is personal and conjugated: he de, has de, ha de, hemos de, habéis de, han de.
Llevar + Gerund / Time for Duration
Llevar + gerundio / tiempo para expresar duración
In Spanish, 'llevar + time + gerund' is a powerful way to say how long you have been doing something. 'Llevo dos años estudiando español' means 'I have been studying Spanish for two years.' You can also use 'llevar + time + sin + infinitive' for negatives: 'Llevo tres días sin dormir' means 'I haven't slept for three days.' In the past, use the imperfect: 'Llevaba una hora esperando' (I had been waiting for an hour). This structure replaces the English present perfect continuous naturally.
Key rule
Use 'llevar + time + gerund' for 'have been doing' and 'llevar + time + sin + infinitive' for 'haven't done for (a period of time).'
Examples
- Llevo dos años estudiando español.He estado estudiando español por dos años.
Spanish prefers 'llevar + gerund' over the present perfect continuous for ongoing duration. The literal translation from English sounds unnatural.
- Llevo tres días sin dormir bien.No he dormido bien por tres días.
For negative duration, use 'llevar + time + sin + infinitive.' This is more natural than translating the English construction.
- Llevaba una hora esperando cuando llegó el autobús.Llevé una hora esperando cuando llegó el autobús.
For past duration that was ongoing when something else happened, use 'llevar' in the imperfect (llevaba), not the preterite.
Common mistakes
Using present perfect continuous instead of llevar
He estado trabajando aquí por tres años.Llevo tres años trabajando aquí.Spanish uses 'llevar + time + gerund' for ongoing duration. The English-style present perfect continuous sounds unnatural.
Using preterite instead of imperfect for past duration
Llevé una hora esperando.Llevaba una hora esperando.Past ongoing duration requires the imperfect (llevaba), since the action was still in progress at the reference point.
Ir + Gerund for Gradual Action
Ir + gerundio para acción gradual
In Spanish, 'ir + gerund' expresses a gradual, progressive action that unfolds over time. 'Voy entendiendo' means 'I'm gradually understanding' or 'I'm starting to understand.' 'Los precios van subiendo' means 'Prices keep going up.' This is different from 'estar + gerund,' which simply describes an action happening right now. 'Ir + gerund' adds the idea that something is developing little by little. You can use it in any tense: 'Iba mejorando' (He was gradually improving).
Key rule
Use 'ir + gerund' to show that an action is happening gradually or progressively over time, unlike 'estar + gerund,' which describes a simple ongoing action.
Examples
- Voy entendiendo mejor la gramática.Estoy entendiendo mejor la gramática.
'Voy entendiendo' emphasizes gradual progress in understanding. 'Estoy entendiendo' would mean understanding at this exact moment.
- Los precios van subiendo cada año.Los precios están subiendo cada año.
'Van subiendo' shows a gradual, ongoing increase. 'Están subiendo' would describe prices rising right now.
- La situación fue mejorando poco a poco.La situación estuvo mejorando poco a poco.
In the past, 'fue mejorando' shows gradual improvement over a period. 'Estuvo mejorando' is less natural for expressing gradual change.
Common mistakes
Confusing 'ir + gerund' with 'estar + gerund'
Estoy aprendiendo poco a poco. (meaning gradual progress)Voy aprendiendo poco a poco.'Estar + gerund' describes an action in progress now. 'Ir + gerund' expresses the gradual, cumulative nature of an action.
Using infinitive instead of gerund after ir
Voy aprender más vocabulario.Voy aprendiendo más vocabulario.'Ir + infinitive' means 'going to do' (future). 'Ir + gerund' means 'gradually doing.' The gerund is essential for the gradual meaning.
Quedar vs Quedarse
Quedar y quedarse
Quedar and quedarse look similar but have different meanings. 'Quedar' (without 'se') means to arrange to meet ('Quedamos a las ocho'), to remain or be left ('Quedan tres entradas'), or to suit or look ('Te queda bien ese vestido'). 'Quedarse' (with 'se') means to stay somewhere ('Me quedé en casa') or to become a certain way ('Se quedó sorprendido'). The reflexive pronoun 'se' makes a big difference in meaning, so pay close attention to whether it is present or not.
Key rule
Use 'quedar' (no pronoun) for arranging to meet, remaining, and suiting; use 'quedarse' (with reflexive pronoun) for staying somewhere or becoming a state.
Examples
- Quedamos a las ocho en la plaza.Nos quedamos a las ocho en la plaza.
'Quedar' (without reflexive) means to arrange to meet. Adding 'nos' would change the meaning to 'we stayed.'
- ¿Cuántas galletas quedan?¿Cuántas galletas se quedan?
'Quedar' (without reflexive) means 'to be left/remain.' The reflexive is not needed here.
- Ese vestido te queda muy bien.Ese vestido te queda se muy bien.
'Quedar' meaning 'to suit or look on someone' uses an indirect object pronoun (te), not a reflexive construction.
Common mistakes
Using reflexive when arranging to meet
Nos quedamos a las cinco en el café.Quedamos a las cinco en el café.'Quedar' for arranging to meet does not use a reflexive pronoun. 'Nos quedamos' would mean 'we stayed.'
Omitting reflexive when meaning 'to stay'
Quedé en casa todo el día.Me quedé en casa todo el día.'Quedarse' (to stay) requires the reflexive pronoun. Without it, the meaning changes to 'I arranged to meet.'
Volver a + Infinitive (To Do Again)
Volver a + infinitivo (hacer algo otra vez)
In Spanish, 'volver a + infinitive' is the most natural way to say 'to do something again.' Instead of saying 'Leo el libro otra vez,' you can say 'Vuelvo a leer el libro' (I'm reading the book again). It works in all tenses: 'Volvió a llamar' (He called again), 'No volveré a hacerlo' (I won't do it again). This construction is very common and sounds more natural than adding 'otra vez' or 'de nuevo' in many cases.
Key rule
Use 'volver a + infinitive' to express doing something again; 'volver' conjugates for subject and tense, and the preposition 'a' must always be present before the infinitive.
Examples
- Volvió a llamar por teléfono.Volvió llamar por teléfono.
The preposition 'a' is required between 'volver' and the infinitive. 'Volvió a llamar' means 'He called again.'
- Vuelvo a repetir la pregunta.Repito la pregunta otra vez.
While 'otra vez' is grammatical, 'volver a + infinitive' is the more natural Spanish construction for 'again.'
- No volveré a hacerlo, te lo prometo.No lo haré otra vez, te lo prometo.
'No volveré a hacerlo' is a stronger, more emphatic way to promise not to do something again.
Common mistakes
Omitting the preposition 'a'
Vuelvo repetir la pregunta.Vuelvo a repetir la pregunta.The preposition 'a' is mandatory in 'volver a + infinitive.' Without it, the sentence is ungrammatical.
Using 'de' instead of 'a'
Volvió de leer el libro.Volvió a leer el libro.'Volver de' means 'to return from a place.' 'Volver a' means 'to do something again.' The prepositions change the meaning entirely.
Verbs of Change (Ponerse, Hacerse, Volverse, Convertirse, Llegar a ser)
Verbos de cambio (ponerse, hacerse, volverse, convertirse en, llegar a ser)
Spanish has several verbs for 'to become,' each used in different situations. 'Ponerse' is for temporary or emotional changes: 'Se puso rojo' (He turned red). 'Hacerse' is for gradual or voluntary changes: 'Se hizo médico' (He became a doctor). 'Volverse' is for permanent, often involuntary changes: 'Se volvió loco' (He went crazy). 'Convertirse en' is for transformations: 'Se convirtió en mariposa' (It turned into a butterfly). 'Llegar a ser' is for achievements: 'Llegó a ser presidente' (He became president).
Key rule
Use ponerse for temporary/emotional changes, hacerse for gradual/voluntary ones, volverse for permanent/involuntary changes, convertirse en for transformations, and llegar a ser for achievements.
Examples
- Se puso nervioso antes del examen.Se hizo nervioso antes del examen.
Nervousness is a temporary emotional state, so use 'ponerse,' not 'hacerse.'
- Se hizo médico después de muchos años de estudio.Se puso médico después de muchos años de estudio.
Becoming a doctor is a gradual, voluntary achievement. Use 'hacerse,' not 'ponerse.'
- Se volvió muy desconfiado con el tiempo.Se puso muy desconfiado con el tiempo.
A permanent personality change uses 'volverse.' 'Ponerse' would imply a temporary state.
Common mistakes
Using 'ponerse' for permanent changes
Se puso loco con los años.Se volvió loco con los años.Permanent personality changes use 'volverse.' 'Ponerse' is only for temporary or emotional states.
Using 'hacerse' for emotional reactions
Se hizo rojo de vergüenza.Se puso rojo de vergüenza.Blushing is a temporary physical reaction, so it requires 'ponerse,' not 'hacerse.'
Dejar vs Dejar de
Dejar y dejar de
The verb 'dejar' has several important uses. By itself, 'dejar' means 'to leave (something)' or 'to allow': 'Dejé las llaves en la mesa' (I left the keys on the table), 'Déjame salir' (Let me leave). 'Dejar de + infinitive' means 'to stop doing something': 'Dejé de fumar' (I stopped smoking). 'No dejar de + infinitive' means 'don't fail to': 'No dejes de visitarnos' (Don't fail to visit us). The difference between 'dejar' and 'dejar de' is crucial because the small word 'de' completely changes the meaning.
Key rule
Use 'dejar' for leaving or allowing, 'dejar de + infinitive' for stopping an action, 'no dejar de' for 'don't fail to,' and 'dejarse' for leaving behind accidentally.
Examples
- Dejé las llaves en la mesa.Dejé de las llaves en la mesa.
'Dejar' (to leave something) is used without 'de' when talking about leaving an object somewhere.
- Dejé de fumar hace tres años.Dejé fumar hace tres años.
'Dejar de + infinitive' means 'to stop doing.' The preposition 'de' is essential to convey 'stopping.'
- Déjame explicarte lo que pasó.Déjame de explicarte lo que pasó.
'Dejar + infinitive' means 'to allow/let.' Adding 'de' would incorrectly change the meaning to 'stop.'
Common mistakes
Omitting 'de' when meaning 'to stop'
Dejé estudiar a las diez.Dejé de estudiar a las diez.'Dejar de' (with 'de') means 'to stop doing.' Without 'de,' 'dejar' means 'to leave' or 'to allow.'
Adding 'de' when meaning 'to allow'
No me dejan de salir.No me dejan salir.'Dejar + infinitive' means 'to allow.' Adding 'de' changes the meaning to 'they don't stop letting me go out.'
Soler in the Imperfect (Past Habits)
Soler en imperfecto (hábitos del pasado)
The verb 'soler' in the imperfect tense is used to talk about things you used to do regularly. 'Solía ir al parque' means 'I used to go to the park.' Soler is a defective verb, meaning it only exists in the present tense (suelo) and the imperfect tense (solía). You cannot use soler in the preterite, future, or conditional. The imperfect conjugation is completely regular: solía, solías, solía, solíamos, solíais, solían. It is always followed by an infinitive.
Key rule
Use 'solía + infinitive' for past habits; soler is defective and only exists in the present (suelo) and imperfect (solía) — never use it in the preterite, future, or conditional.
Examples
- Solía ir al parque todos los domingos.Solí ir al parque todos los domingos.
'Soler' cannot be used in the preterite. The imperfect 'solía' is the only past form available.
- Solíamos cenar juntos los viernes.Soleríamos cenar juntos los viernes.
'Soler' has no conditional form. Use only the imperfect 'solíamos' for past habits.
- De joven, solía leer mucho.De joven, soleré leer mucho.
'Soler' has no future tense. It only exists in the present and imperfect.
Common mistakes
Using soler in the preterite
Solí ir al cine los sábados.Solía ir al cine los sábados.'Soler' is a defective verb with no preterite form. Always use the imperfect 'solía' for past habits.
Using soler in the future
Soleré hacer más ejercicio.Voy a hacer más ejercicio. / Haré más ejercicio.'Soler' cannot be used in the future tense. Express future intentions with 'ir a + infinitive' or the simple future.
Subjunctive After Emotion Verbs
Subjuntivo con verbos de emoción
When you express an emotion about something someone else does, Spanish requires the subjunctive in the second clause. Verbs like alegrarse de que, sentir que, temer que, molestar que, encantar que, and sorprender que all trigger the subjunctive. For example, 'Me alegro de que estés bien' (I'm glad you're well). If the subject is the same for both verbs, use the infinitive instead: 'Me alegro de estar aquí' (I'm glad to be here).
Key rule
Use the subjunctive after emotion verbs when the subject changes; use the infinitive when the subject is the same.
Examples
- Me alegro de que estés bien.Me alegro de que estás bien.
'Alegrarse de que' expresses emotion and triggers the subjunctive: 'estés,' not indicative 'estás.'
- Siento que no puedas venir a la fiesta.Siento que no puedes venir a la fiesta.
'Sentir que' (to be sorry that) triggers subjunctive: 'puedas,' not 'puedes.'
- Me molesta que hablen tan alto.Me molesta que hablan tan alto.
'Molestar que' expresses annoyance, an emotion, so the subjunctive 'hablen' is required.
Common mistakes
Using indicative instead of subjunctive after emotion verbs
Me alegro de que tienes un buen trabajo.Me alegro de que tengas un buen trabajo.Emotion verbs require the subjunctive in the subordinate clause. 'Tienes' must become 'tengas.'
Using subjunctive when the subject is the same
Me alegro de que yo esté aquí.Me alegro de estar aquí.When the subject is the same for both verbs, use the infinitive, not que + subjunctive.
Subjunctive After Doubt and Denial
Subjuntivo con expresiones de duda y negación
When you express doubt or deny something in Spanish, the verb in the subordinate clause must be in the subjunctive. Common triggers include dudar que, no creer que, no pensar que, negar que, and no estar seguro de que. For example, 'No creo que sea verdad' (I don't think it's true). However, when you express certainty, you use the indicative: 'Creo que es verdad' (I think it's true). The key is that negation of belief triggers the subjunctive.
Key rule
Doubt and denial (dudar que, no creer que, negar que) trigger the subjunctive; certainty (creer que, estar seguro de que) takes the indicative.
Examples
- Dudo que él sepa la respuesta.Dudo que él sabe la respuesta.
'Dudar que' expresses doubt, requiring subjunctive: 'sepa,' not indicative 'sabe.'
- No creo que sea verdad.No creo que es verdad.
'No creer que' triggers subjunctive because it negates belief: 'sea,' not 'es.'
- Creo que es verdad.Creo que sea verdad.
'Creer que' (affirmative) expresses certainty, so use indicative 'es,' not subjunctive 'sea.'
Common mistakes
Using indicative after 'no creer que'
No creo que tiene razón.No creo que tenga razón.The negation of 'creer' introduces doubt, which requires the subjunctive: 'tenga,' not 'tiene.'
Using subjunctive after affirmative 'creer que'
Creo que sea importante.Creo que es importante.Affirmative 'creer que' expresses certainty and takes the indicative: 'es,' not 'sea.'
Subjunctive After Desire and Request Verbs
Subjuntivo con verbos de deseo y petición
When you want, wish, ask, or request that someone else do something, Spanish uses the subjunctive in the subordinate clause. Common triggers include querer que, desear que, pedir que, rogar que, necesitar que, exigir que, preferir que, recomendar que, sugerir que, and aconsejar que. For example, 'Quiero que vengas' (I want you to come). When the subject is the same, use the infinitive: 'Quiero venir' (I want to come).
Key rule
Use the subjunctive after desire and request verbs when the subject changes; use the infinitive when the subject is the same.
Examples
- Quiero que vengas a mi fiesta.Quiero que vienes a mi fiesta.
'Querer que' triggers subjunctive when subjects differ: 'vengas,' not indicative 'vienes.'
- Quiero venir a tu fiesta.Quiero que yo venga a tu fiesta.
Same subject (yo) for both verbs, so use infinitive 'venir,' not que + subjunctive.
- Te pido que me ayudes.Te pido que me ayudas.
'Pedir que' is a request verb requiring subjunctive: 'ayudes,' not 'ayudas.'
Common mistakes
Using indicative after 'querer que'
Quiero que vienes conmigo.Quiero que vengas conmigo.'Querer que' always triggers the subjunctive when subjects differ: 'vengas,' not 'vienes.'
Using que + subjunctive with the same subject
Quiero que yo salga temprano.Quiero salir temprano.Same subject for both verbs requires the infinitive, not que + subjunctive.
Subjunctive After Impersonal Expressions
Subjuntivo con expresiones impersonales
Impersonal expressions that express judgment, possibility, or necessity trigger the subjunctive. These include es importante que, es necesario que, es posible que, es probable que, es mejor que, es una lástima que, está bien que, es raro que, and es normal que. For example, 'Es importante que estudies' (It's important that you study). However, impersonal expressions of certainty take the indicative: 'Es verdad que tiene razón' (It's true that he's right).
Key rule
Impersonal expressions of judgment, possibility, or necessity take the subjunctive; those expressing certainty take the indicative.
Examples
- Es importante que estudies todos los días.Es importante que estudias todos los días.
'Es importante que' expresses a value judgment, requiring subjunctive 'estudies.'
- Es posible que tengamos un examen mañana.Es posible que tenemos un examen mañana.
'Es posible que' expresses possibility, triggering subjunctive 'tengamos.'
- Es necesario que todos participen.Es necesario que todos participan.
'Es necesario que' expresses necessity, requiring subjunctive 'participen.'
Common mistakes
Using indicative after 'es importante que'
Es importante que comes bien.Es importante que comas bien.'Es importante que' is a judgment expression requiring the subjunctive: 'comas,' not 'comes.'
Using subjunctive after 'es verdad que'
Es verdad que sea difícil.Es verdad que es difícil.'Es verdad que' states a fact and takes the indicative: 'es,' not 'sea.'
Ojalá + Subjunctive
Ojalá + subjuntivo
Ojalá is a powerful word in Spanish that always triggers the subjunctive, with no exceptions. It comes from the Arabic expression 'inshallah' (God willing) and is used to express wishes and hopes. With the present subjunctive, it expresses a wish for the future: 'Ojalá llueva mañana' (I hope it rains tomorrow). With the present perfect subjunctive, it expresses a wish about the recent past: 'Ojalá haya llegado bien' (I hope he arrived safely). Ojalá can also be used with 'que' but it is optional: 'Ojalá que todo salga bien.'
Key rule
Ojalá always triggers the subjunctive with no exceptions—use present subjunctive for future wishes and present perfect subjunctive for wishes about the recent past.
Examples
- Ojalá llueva mañana.Ojalá llueve mañana.
Ojalá always requires subjunctive: 'llueva,' not indicative 'llueve.'
- Ojalá que todo salga bien.Ojalá que todo sale bien.
Even with optional 'que,' ojalá requires subjunctive: 'salga,' not 'sale.'
- Ojalá aprueben todos el examen.Ojalá aprueban todos el examen.
Ojalá + subjunctive 'aprueben,' not indicative 'aprueban.'
Common mistakes
Using indicative after ojalá
Ojalá tengo suerte.Ojalá tenga suerte.Ojalá always requires the subjunctive, no exceptions. Use 'tenga,' not 'tengo.'
Using indicative perfect instead of subjunctive perfect
Ojalá ha ido bien.Ojalá haya ido bien.For wishes about the past, use present perfect subjunctive: 'haya ido,' not indicative 'ha ido.'
Subjunctive in Purpose Clauses
Subjuntivo en cláusulas de finalidad
When you explain the purpose of an action for someone else, Spanish uses the subjunctive after conjunctions like para que, a fin de que, and con el objetivo de que. For example, 'Te lo digo para que lo sepas' (I'm telling you so that you know). When the subject is the same for both actions, use para + infinitive instead: 'Estudio para aprender' (I study in order to learn). The conjunction 'a que' also triggers subjunctive in purpose clauses: 'Vine a que me ayudaras.'
Key rule
Use para que + subjunctive when the purpose involves a different subject; use para + infinitive when the subject is the same.
Examples
- Te lo digo para que lo sepas.Te lo digo para que lo sabes.
'Para que' introduces purpose with a different subject, requiring subjunctive 'sepas.'
- Estudio para aprender.Estudio para que aprenda.
Same subject (yo) for both verbs, so use para + infinitive 'aprender,' not para que + subjunctive.
- Habla más alto para que todos te oigan.Habla más alto para que todos te oyen.
Different subjects (tú/todos) require para que + subjunctive: 'oigan,' not 'oyen.'
Common mistakes
Using indicative after 'para que'
Te llamo para que sabes la noticia.Te llamo para que sepas la noticia.'Para que' always triggers the subjunctive: 'sepas,' not indicative 'sabes.'
Using 'para que' with the same subject
Estudio para que yo aprenda.Estudio para aprender.When the subject is the same, use para + infinitive, not para que + subjunctive.
Subjunctive After Temporal Conjunctions (Future)
Subjuntivo con conjunciones temporales (futuro)
When temporal conjunctions like cuando, hasta que, en cuanto, tan pronto como, and después de que refer to future actions, Spanish uses the subjunctive. For example, 'Cuando llegues, llámame' (When you arrive, call me). However, when they refer to habitual or past actions, the indicative is used: 'Cuando llego a casa, como' (When I get home, I eat). One important exception: 'antes de que' always takes the subjunctive, even when referring to the past.
Key rule
Use the subjunctive after temporal conjunctions (cuando, hasta que, en cuanto, etc.) for future events; use the indicative for habitual or past events; 'antes de que' always takes the subjunctive.
Examples
- Cuando llegues, llámame.Cuando llegas, llámame.
Future event: use subjunctive 'llegues' after 'cuando,' not present indicative 'llegas.'
- Cuando llego a casa, siempre como.Cuando llegue a casa, siempre como.
Habitual action: use indicative 'llego' after 'cuando,' not subjunctive 'llegue.'
- Esperaré hasta que termines.Esperaré hasta que terminas.
Future event: 'hasta que' + subjunctive 'termines,' not indicative 'terminas.'
Common mistakes
Using indicative after 'cuando' for future events
Cuando tengo dinero, compraré un coche.Cuando tenga dinero, compraré un coche.Future event requires subjunctive after 'cuando': 'tenga,' not present indicative 'tengo.'
Using subjunctive after 'cuando' for habitual actions
Cuando llegue a casa, siempre ceno.Cuando llego a casa, siempre ceno.Habitual action uses the indicative: 'llego,' not subjunctive 'llegue.'
Subjunctive in Relative Clauses (Unknown Antecedent)
Subjuntivo en cláusulas relativas (antecedente desconocido)
When you describe something or someone that you are looking for but don't know if it exists, Spanish uses the subjunctive in the relative clause. For example, 'Busco un libro que sea interesante' (I'm looking for a book that is interesting—I haven't found it yet). But if the thing exists and you know it, use the indicative: 'Tengo un libro que es interesante' (I have a book that is interesting). Questions about existence also trigger the subjunctive: '¿Hay alguien que sepa francés?' (Is there anyone who knows French?).
Key rule
Use the subjunctive in relative clauses when the antecedent is unknown or hypothetical; use the indicative when the antecedent is known and specific.
Examples
- Busco un libro que sea interesante.Busco un libro que es interesante.
The book is hypothetical (not yet found), so use subjunctive 'sea,' not indicative 'es.'
- Tengo un libro que es interesante.Tengo un libro que sea interesante.
The book exists (I have it), so use indicative 'es,' not subjunctive 'sea.'
- ¿Hay alguien que sepa francés?¿Hay alguien que sabe francés?
Questioning existence triggers subjunctive: 'sepa,' not indicative 'sabe.'
Common mistakes
Using indicative for unknown antecedent
Busco a alguien que habla japonés.Busco a alguien que hable japonés.The person is hypothetical (not yet found), requiring subjunctive 'hable,' not indicative 'habla.'
Using subjunctive for known antecedent
Tengo un amigo que hable alemán.Tengo un amigo que habla alemán.The friend exists and is known, so use indicative 'habla,' not subjunctive 'hable.'
Subjunctive After Negative Antecedent
Subjuntivo con antecedente negativo
When a relative clause describes something that doesn't exist, Spanish uses the subjunctive. This happens after negative words like no hay nadie que, no conozco a nadie que, no existe ningún... que, and similar patterns. For example, 'No hay nadie que sepa la respuesta' (There is no one who knows the answer). The negation combined with the relative clause triggers the subjunctive because you are talking about something nonexistent.
Key rule
Use the subjunctive in relative clauses after a negative antecedent (no hay nadie que, no existe nada que, etc.) because you are describing something that does not exist.
Examples
- No hay nadie que sepa la respuesta.No hay nadie que sabe la respuesta.
Negative antecedent (nadie) requires subjunctive: 'sepa,' not indicative 'sabe.'
- No conozco a nadie que hable chino.No conozco a nadie que habla chino.
Negative antecedent: the person doesn't exist in speaker's experience. Use subjunctive 'hable.'
- No existe ningún lugar que sea perfecto.No existe ningún lugar que es perfecto.
Negated existence requires subjunctive: 'sea,' not indicative 'es.'
Common mistakes
Using indicative after 'no hay nadie que'
No hay nadie que sabe cocinar aquí.No hay nadie que sepa cocinar aquí.Negative antecedent (nadie) always triggers subjunctive: 'sepa,' not indicative 'sabe.'
Using indicative after 'no existe ningún... que'
No existe ningún país que tiene todo.No existe ningún país que tenga todo.Negated existence requires subjunctive: 'tenga,' not 'tiene.'
Subjunctive After 'Es + Adjective + Que' (Judgment)
Subjuntivo con 'es + adjetivo + que' (juicio de valor)
When you use 'es + adjective + que' to express a judgment or evaluation, Spanish requires the subjunctive. Examples include es bueno que, es malo que, es extraño que, es lógico que, es injusto que, es increíble que, and es absurdo que. For instance, 'Es increíble que hables tan bien' (It's incredible that you speak so well). However, when stating a fact, use the indicative: 'Es cierto que habla bien' (It's certain that she speaks well).
Key rule
Use the subjunctive after 'es + adjective + que' when the adjective expresses judgment or evaluation; use the indicative when it states factual certainty (es cierto que, es evidente que, es obvio que).
Examples
- Es increíble que hables tres idiomas.Es increíble que hablas tres idiomas.
'Es increíble que' expresses amazement (judgment), requiring subjunctive 'hables.'
- Es lógico que estés cansado después de trabajar tanto.Es lógico que estás cansado después de trabajar tanto.
'Es lógico que' is a judgment expression, requiring subjunctive 'estés.'
- Es injusto que gane menos que sus compañeros.Es injusto que gana menos que sus compañeros.
'Es injusto que' expresses a value judgment, requiring subjunctive 'gane.'
Common mistakes
Using indicative after evaluative adjectives
Es bueno que comes fruta todos los días.Es bueno que comas fruta todos los días.'Es bueno que' is a value judgment, requiring subjunctive 'comas,' not indicative 'comes.'
Using subjunctive after factual adjectives
Es obvio que tenga mucho dinero.Es obvio que tiene mucho dinero.'Es obvio que' states a fact, requiring indicative 'tiene,' not subjunctive 'tenga.'
Lo + Adjective as Abstract Noun
Lo + adjetivo como sustantivo abstracto
In Spanish, you can place the neuter article 'lo' before an adjective to create an abstract noun. 'Lo importante' means 'the important thing' or 'what's important.' 'Lo bueno' means 'the good thing' and 'lo mejor' means 'the best thing.' This structure lets you talk about abstract concepts without naming a specific noun. Additionally, 'lo + adjective + que' expresses 'how' in exclamatory or emphatic sentences: 'No sabes lo difícil que es' means 'You don't know how difficult it is.'
Key rule
Place the neuter article 'lo' before an adjective (always masculine singular) to create an abstract noun meaning 'the ... thing/part,' and use 'lo + adjective + que' to express 'how' emphatically.
Examples
- Lo importante es estudiar todos los días.El importante es estudiar todos los días.
Use neuter 'lo' (not 'el') before an adjective to form an abstract noun: 'lo importante' = the important thing.
- Lo bueno de esta ciudad es el clima.El bueno de esta ciudad es el clima.
'Lo bueno' means 'the good thing'; 'el bueno' would mean 'the good one' (referring to a specific masculine noun).
- Lo mejor de la fiesta fue la música.La mejor de la fiesta fue la música.
'Lo mejor' (the best thing/part) uses neuter 'lo' because it refers to an abstract concept, not a specific noun.
Common mistakes
Using 'el' instead of 'lo' for abstract concepts
El difícil es empezar.Lo difícil es empezar.When referring to an abstract concept ('the difficult thing/part'), use the neuter article 'lo', not the masculine 'el.'
Making the adjective agree with a feminine or plural referent in the basic construction
Lo buena de la vida es la familia.Lo bueno de la vida es la familia.In the basic 'lo + adjective' construction, the adjective is always masculine singular regardless of context.
Mixed Gender Plural Agreement
Concordancia en plural de género mixto
When a group includes both masculine and feminine members, Spanish uses the masculine plural form for adjectives and pronouns. For example, 'Los niños y las niñas están contentos' uses 'contentos' (not 'contentas') because the group is mixed. The word 'hermanos' can mean 'brothers' or 'siblings' depending on context. Even if there is only one male in a large group of females, the masculine plural is traditionally used. This rule applies to all adjectives, past participles, and pronouns referring to mixed groups.
Key rule
When a group contains both masculine and feminine nouns, all agreeing adjectives, participles, and pronouns take the masculine plural form.
Examples
- Los niños y las niñas están contentos.Los niños y las niñas están contentas.
Mixed-gender group requires masculine plural 'contentos,' not feminine 'contentas.'
- Mi hermano y mi hermana son muy simpáticos.Mi hermano y mi hermana son muy simpáticas.
A mixed pair uses masculine plural: 'simpáticos' covers both the brother and the sister.
- La mesa y el sofá son nuevos.La mesa y el sofá son nuevas.
Even with objects, mixed genders default to masculine plural: mesa (f.) + sofá (m.) → nuevos.
Common mistakes
Using feminine plural when the last noun is feminine
Los libros y las revistas son interesantes → Los libros y las revistas son interesantas.Los libros y las revistas son interesantes.Agreement is based on the mixed group as a whole (masculine plural), not the last noun mentioned. Note: 'interesantes' is the same for both genders.
Not recognizing masculine plural as inclusive
Mis hermanos y hermanas van a la fiesta.Mis hermanos van a la fiesta. (if meaning siblings)'Mis hermanos' already includes brothers and sisters. Adding 'hermanas' is redundant unless you want to emphasize both groups.
Adjective Position Changes Meaning
Posición del adjetivo cambia el significado
In Spanish, some adjectives change meaning depending on whether they come before or after the noun. 'Un gran hombre' means 'a great man,' but 'un hombre grande' means 'a big/tall man.' 'Mi viejo amigo' means 'my longstanding friend,' but 'mi amigo viejo' means 'my elderly friend.' Similarly, 'pobre' before the noun means 'unfortunate' and after the noun means 'poor/without money.' Learning these position-dependent meanings is essential for precise communication in Spanish.
Key rule
Adjectives like grande, pobre, viejo, nuevo, único, cierto, medio, and mismo have figurative or subjective meanings before the noun and literal or objective meanings after the noun.
Examples
- Es un gran músico. (He's a great musician.)Es un grande músico. (intended: great)
Before singular nouns, 'grande' shortens to 'gran' and means 'great/remarkable,' not 'big.'
- El pobre hombre perdió su trabajo. (The unfortunate man lost his job.)El hombre pobre perdió su trabajo. (intended: unfortunate)
'Pobre' before the noun means 'unfortunate'; after the noun it means 'poor/without money.'
- Es mi viejo amigo. (He's my longstanding friend.)Es mi amigo viejo. (intended: longstanding)
'Viejo' before the noun means 'longstanding/old as in long-known'; after means 'elderly.'
Common mistakes
Using 'pobre' after the noun when meaning 'unfortunate'
La mujer pobre tuvo un accidente. (intended: unfortunate)La pobre mujer tuvo un accidente.'Pobre' after the noun means 'poor/without money.' To express 'unfortunate,' place it before: 'la pobre mujer.'
Confusing 'nuevo' before and after the noun
Compré un coche nuevo. (intended: a different car, not brand-new)Compré un nuevo coche. (another/different car)'Un coche nuevo' means a brand-new car. 'Un nuevo coche' means another/different car (not necessarily brand-new).
Emphatic Prepositional Pronoun Construction
Construcción enfática con pronombre preposicional
In Spanish, you can add 'a mí,' 'a ti,' 'a él,' etc. before the indirect object pronoun for emphasis or contrast. 'Me gusta el café' becomes 'A mí me gusta el café' to stress that it's specifically you who likes coffee. This is required for clarity with 'le/les' since 'le' can mean 'to him,' 'to her,' or 'to you (formal)': 'A ella le gusta' vs 'A él le gusta.' It is mandatory after 'también' and 'tampoco': 'A mí también' (me too), 'A ella tampoco' (her neither).
Key rule
Add 'a mí/ti/él/ella...' for emphasis or disambiguation, but always keep the indirect object pronoun (me, te, le...) — never omit it when the prepositional phrase is present.
Examples
- A mí me gusta el chocolate.A mí gusta el chocolate.
The indirect object pronoun 'me' is required even when 'a mí' is present; you cannot drop it.
- A ella le parece bien la idea.Le parece bien la idea. (when context is ambiguous)
'A ella' clarifies that 'le' refers to 'her,' not 'him' or 'you (formal).'
- A ti te interesa la ciencia, ¿verdad?A ti interesa la ciencia, ¿verdad?
'Te' must remain even with emphatic 'a ti.' Both elements are needed together.
Common mistakes
Omitting the indirect object pronoun when using the prepositional phrase
A mí gusta la música.A mí me gusta la música.The indirect object pronoun 'me' is always required. 'A mí' adds emphasis but does not replace 'me.'
Using 'yo' instead of 'mí' after the preposition
A yo me parece bien.A mí me parece bien.After prepositions, use prepositional pronouns: 'mí' (not 'yo'), 'ti' (not 'tú'). Other forms match: él, ella, nosotros, etc.
Relative Pronouns: El cual & Quien
Pronombres relativos: el cual y quien
Spanish has relative pronouns 'el cual/la cual/los cuales/las cuales' and 'quien/quienes' used mainly after prepositions. 'La casa en la cual vivo' means 'The house in which I live.' 'La persona con quien hablé' means 'The person with whom I spoke.' 'Quien' is only for people, while 'el cual' works for both people and things. 'El que/la que' are common alternatives to 'el cual/la cual' in everyday speech. These pronouns must agree in gender and number with the noun they refer to.
Key rule
Use 'el cual/la cual' (agrees in gender and number) or 'quien/quienes' (people only) after prepositions in relative clauses; 'el que/la que' are everyday alternatives to 'el cual.'
Examples
- La casa en la cual vivo es pequeña.La casa en cual vivo es pequeña.
'El cual' must include the article matching the antecedent: 'la casa' (feminine) → 'la cual.'
- La persona con quien hablé era muy amable.La persona con que hablé era muy amable.
After prepositions referring to people, 'quien' is preferred over 'que' in careful speech.
- Los libros sobre los cuales escribí están agotados.Los libros sobre los quien escribí están agotados.
'Quien' is only for people. For things, use 'el cual' (here: 'los cuales' for masculine plural 'libros').
Common mistakes
Using 'quien' for things instead of people
El problema sobre quien hablamos es grave.El problema sobre el cual hablamos es grave.'Quien' refers exclusively to people. For things, use 'el cual' or 'el que.'
Forgetting gender/number agreement with 'el cual'
Las ciudades en el cual viví son grandes.Las ciudades en las cuales viví son grandes.'El cual' must match the antecedent: 'ciudades' (fem. pl.) → 'las cuales.'
Halfway there — imagine actually using all of this.

Todo/a/os/as as Pronoun
Todo/a/os/as como pronombre
In Spanish, 'todo/a/os/as' can work as a pronoun meaning 'everything,' 'everyone,' or 'all.' 'Todo es posible' means 'Everything is possible.' 'Todos vinieron' means 'Everyone came.' As a pronoun with a verb, it usually comes before the verb: 'Todos lo saben' (Everyone knows it), not 'Lo todos saben.' When used as a determiner before a noun, it requires the article: 'todas las casas' (all the houses), not 'todas casas.' The expression 'todo el mundo' means 'everyone.'
Key rule
As a pronoun, 'todo' (everything) and 'todos/as' (everyone) stand alone; as a determiner, always include the article: 'todos los' / 'todas las' + noun.
Examples
- Todo es posible si trabajas duro.Todos es posible si trabajas duro.
'Todo' (singular, neuter) means 'everything.' 'Todos' means 'everyone' (people).
- Todos vinieron a la fiesta.Todo vinieron a la fiesta.
'Todos' (plural) means 'everyone' and takes a plural verb. 'Todo' would mean 'everything.'
- Lo sé todo.Sé lo todo.
As a direct object, 'todo' typically follows the verb: 'Lo sé todo' (I know everything).
Common mistakes
Omitting the article when 'todo' is a determiner
Todas personas necesitan agua.Todas las personas necesitan agua.When 'todo/a/os/as' precedes a noun, the definite article is required between them: 'todas las personas.'
Confusing 'todo' (everything) with 'todos' (everyone)
Todos es interesante. (intended: everything)Todo es interesante.'Todo' (singular, neuter) means 'everything.' 'Todos' (masculine plural) means 'everyone' (people).
Impersonal Se
Se impersonal
Impersonal 'se' is used to make general statements without specifying who performs the action, similar to English 'one,' 'people,' or 'you' in a general sense. 'Se dice que...' means 'It is said that...' or 'People say that...' 'Se vive bien aquí' means 'One lives well here.' '¿Cómo se dice...?' means 'How do you say...?' The verb with impersonal 'se' is always in the third person singular. This is different from passive 'se,' where the verb agrees with the logical subject.
Key rule
Impersonal 'se' always takes a third person singular verb and expresses general statements without a specific subject; it differs from passive 'se,' which agrees with the logical subject.
Examples
- Se dice que va a llover mañana.Se dicen que va a llover mañana.
Impersonal 'se' always takes singular verb: 'se dice' (it is said/people say), not 'se dicen.'
- Se vive bien en esta ciudad.Se viven bien en esta ciudad.
With intransitive verbs, impersonal 'se' is always singular: 'se vive,' not 'se viven.'
- ¿Cómo se dice 'hello' en español?¿Cómo se dicen 'hello' en español?
Asking 'How does one say...?' uses impersonal 'se' with singular 'dice.'
Common mistakes
Making the verb plural with impersonal 'se'
Se viven bien en este país.Se vive bien en este país.Impersonal 'se' always takes a singular verb. The verb does not agree with any element because there is no grammatical subject.
Confusing impersonal 'se' with passive 'se'
Se vende coches. (intended: Cars are sold)Se venden coches. (passive se, verb agrees with 'coches')If the meaning is 'cars are sold' (passive), the verb must agree with 'coches' (plural): 'se venden.' Impersonal 'se vende coches' is sometimes used colloquially but is less standard.
Passive Se
Se pasivo
Passive 'se' is used to express that something happens to a thing without saying who does it. The verb agrees with the thing being acted upon. 'Se venden coches' means 'Cars are sold' (coches is plural, so 'venden' is plural). 'Se habla español' means 'Spanish is spoken' (español is singular, so 'habla' is singular). This is different from impersonal 'se,' where the verb is always singular. Passive 'se' is extremely common in signs, advertisements, and everyday speech. The grammatical subject typically comes after the verb.
Key rule
In passive 'se,' the verb agrees in number with the grammatical subject (the thing acted upon): singular noun = singular verb, plural noun = plural verb.
Examples
- Se venden coches de segunda mano.Se vende coches de segunda mano.
'Coches' is plural, so the verb must be plural: 'se venden,' not 'se vende.'
- Se habla español en muchos países.Se hablan español en muchos países.
'Español' is singular, so the verb is singular: 'se habla,' not 'se hablan.'
- Se hablan tres idiomas en Suiza.Se habla tres idiomas en Suiza.
'Tres idiomas' is plural, so the verb agrees: 'se hablan,' not 'se habla.'
Common mistakes
Not making the verb agree with the plural subject
Se vende libros en esta tienda.Se venden libros en esta tienda.'Libros' is the grammatical subject (plural), so the verb must be plural: 'se venden.'
Making the verb plural with a singular subject
Se necesitan un electricista.Se necesita un electricista.'Un electricista' is singular, so the verb must be singular: 'se necesita.'
Advanced Por vs Para Distinctions
Por vs Para - Distinciones avanzadas
At B1 level, you need to master the subtler uses of 'por' and 'para'. 'Por' can indicate exchange ('Lo compré por 20 euros'), cause ('Se canceló por la lluvia'), frequency ('tres veces por semana'), acting on someone's behalf ('Votó por el candidato'), and means of communication ('por teléfono'). 'Para' expresses purpose, deadlines ('para el lunes'), personal opinion ('para mí es fácil'), and surprising comparisons ('Para ser niño, es muy maduro'). These more advanced distinctions go beyond the basic cause-vs-purpose contrast you learned at A2.
Key rule
Por looks backward (cause, exchange, means, rate, on behalf of); para looks forward (purpose, deadline, opinion, comparison against expectations).
Examples
- Lo compré por 20 euros.Lo compré para 20 euros.
'Por' indicates the price paid in an exchange - I bought it for (in exchange for) 20 euros.
- Gracias por tu ayuda.Gracias para tu ayuda.
'Por' is always used with 'gracias' to indicate the cause of gratitude.
- Se canceló el partido por la lluvia.Se canceló el partido para la lluvia.
'Por' expresses the cause - the game was canceled because of the rain.
Common mistakes
Using 'para' for price or exchange
Pagué 50 euros para esta camisa.Pagué 50 euros por esta camisa.'Por' is used for prices and exchanges - the amount given in exchange for the item.
Using 'para' for cause
La carretera está cerrada para la nieve.La carretera está cerrada por la nieve.'Por' expresses the cause or reason - the road is closed because of the snow.
Compound Prepositions
Preposiciones compuestas
Compound prepositions are made of two or more words and typically end with 'de'. They describe precise locations and spatial relationships. Common ones include 'debajo de' (under), 'encima de' (on top of), 'al lado de' (next to), 'delante de' (in front of), 'detrás de' (behind), 'dentro de' (inside), 'fuera de' (outside), 'cerca de' (near), and 'lejos de' (far from). At B1 level you also learn 'enfrente de' (opposite), 'alrededor de' (around), and 'a través de' (through).
Key rule
Compound prepositions end with 'de' (debajo de, encima de, etc.); never omit the 'de', and always contract 'de + el' to 'del'.
Examples
- El gato está debajo de la cama.El gato está debajo la cama.
'Debajo de' (under) always requires 'de' before the noun.
- La farmacia está enfrente del hospital.La farmacia está enfrente de el hospital.
'Enfrente de' (opposite) requires 'de', and 'de + el' contracts to 'del'.
- Hay un jardín alrededor de la casa.Hay un jardín alrededor la casa.
'Alrededor de' (around) requires 'de' to connect to the noun.
Common mistakes
Omitting 'de' in compound prepositions
Vive cerca mi casa.Vive cerca de mi casa.All compound prepositions ending in 'de' require this particle to connect to the following noun.
Not contracting 'de + el' to 'del'
Está delante de el colegio.Está delante del colegio.The contraction 'del' is always mandatory when 'de' is followed by 'el'.
Al + Infinitive for 'Upon Doing'
Al + infinitivo - Uso temporal
In Spanish, you can combine 'al' (a + el) with an infinitive to mean 'upon doing' or 'when doing' something. For example, 'Al llegar a casa, llamé a mi madre' means 'Upon arriving home, I called my mother.' This construction shows that two actions happen at the same time or that one immediately follows the other. It is a more formal or literary way of saying 'cuando + conjugated verb' and is very common in written Spanish.
Key rule
Use 'al + infinitive' to express 'upon/when doing something,' indicating two actions that happen simultaneously or in immediate succession.
Examples
- Al llegar a casa, me quité los zapatos.A llegar a casa, me quité los zapatos.
'Al' (a + el) is required before the infinitive, not just 'a'. The contraction is mandatory.
- Al verla, se puso muy contento.Al viendo ella, se puso muy contento.
Use the infinitive after 'al', not the gerund. 'Al ver' is correct, not 'al viendo'.
- Al abrir la puerta, encontré un paquete.Al abriendo la puerta, encontré un paquete.
The infinitive follows 'al', never the gerund (-ando/-iendo form).
Common mistakes
Using the gerund instead of the infinitive
Al saliendo de clase, vi a mi amigo.Al salir de clase, vi a mi amigo.'Al' must be followed by an infinitive, never by a gerund (-ando/-iendo).
Using a conjugated verb after 'al'
Al llegó a casa, encendió la luz.Al llegar a casa, encendió la luz.'Al' is always followed by an infinitive, not a conjugated verb form.
De + Infinitive for Conditional Meaning
De + infinitivo - Significado condicional
In Spanish, you can use 'de + infinitive' to express a condition, much like 'if' in English. For example, 'De haberlo sabido, no habría venido' means 'If I had known, I wouldn't have come.' Another example is 'De ser posible, me gustaría ir' (If it were possible, I'd like to go). This construction is more common in formal or literary Spanish and is equivalent to using 'si + conjugated verb.' It adds elegance to your writing.
Key rule
Use 'de + infinitive' as a formal equivalent of 'si + conjugated verb' to express conditional or hypothetical situations.
Examples
- De haberlo sabido, no habría venido.De lo habría sabido, no habría venido.
'De + compound infinitive' (haber + past participle) expresses a past counterfactual: 'If I had known.'
- De ser posible, me gustaría asistir.De siendo posible, me gustaría asistir.
'De' is followed by an infinitive, not a gerund. 'De ser posible' = 'If it were possible.'
- De tener más dinero, viajaría por todo el mundo.De teniendo más dinero, viajaría por todo el mundo.
'De + infinitive' replaces 'Si tuviera más dinero' - a present/future hypothetical.
Common mistakes
Using a gerund instead of an infinitive
De teniendo tiempo, te ayudaría.De tener tiempo, te ayudaría.'De' in conditional meaning is always followed by an infinitive, never a gerund.
Using a conjugated verb after 'de'
De tuve dinero, compraría una casa.De tener dinero, compraría una casa.'De' must be followed by an infinitive (simple or compound), not a conjugated form.
Prepositions Required After Adjectives
Preposiciones regidas por adjetivos
Many Spanish adjectives must be followed by a specific preposition, and you need to memorize which one goes with each adjective. The most common pattern is adjective + 'de': 'capaz de' (capable of), 'cansado de' (tired of), 'seguro de' (sure of), 'lleno de' (full of), 'difícil de' (difficult to). Others take 'a': 'acostumbrado a' (used to), 'dispuesto a' (willing to), 'parecido a' (similar to). Some take 'en': 'interesado en' (interested in), 'bueno en' (good at). These combinations are fixed and must be learned as units.
Key rule
Each adjective requires a specific preposition: most take 'de' (capaz de, cansado de, fácil de), some take 'a' (dispuesto a, acostumbrado a), and others take 'en' (interesado en, bueno en).
Examples
- Es capaz de resolver cualquier problema.Es capaz a resolver cualquier problema.
'Capaz' always takes 'de': 'capaz de' (capable of).
- Estoy cansado de esperar.Estoy cansado con esperar.
'Cansado' takes 'de': 'cansado de' (tired of).
- Este problema es difícil de entender.Este problema es difícil a entender.
'Difícil' and 'fácil' take 'de': 'difícil de' (difficult to), 'fácil de' (easy to).
Common mistakes
Using 'de' with adjectives that require 'a'
No estoy acostumbrado de comer tan tarde.No estoy acostumbrado a comer tan tarde.'Acostumbrado' requires 'a', not 'de'. Think of it as 'accustomed to'.
Using 'a' with adjectives that require 'de'
Es incapaz a decir la verdad.Es incapaz de decir la verdad.'Incapaz' requires 'de': 'incapaz de' (incapable of).
Por/Para with Ser and Estar
Por/Para con ser y estar
When you combine 'por' and 'para' with 'ser' and 'estar,' you get some very useful expressions. 'Estar por + infinitive' means 'to be about to' or 'to be tempted to': 'Está por llegar' (He's about to arrive), 'Estoy por rendirme' (I'm tempted to give up). 'Estar para + infinitive' means 'to be about to' as well: 'Está para llover' (It's about to rain). With 'ser': 'Es por eso' means 'That's why,' 'La fiesta es para celebrar' expresses purpose, and 'El regalo es para ti' tells us the recipient.
Key rule
Estar por/para + infinitive expresses imminence or inclination; ser por indicates cause; ser para indicates purpose or recipient.
Examples
- Está por llegar el autobús.Está para llegar el autobús.
'Estar por + infinitive' means 'about to' or 'on the verge of' - the bus is about to arrive.
- Está para llover, lleva el paraguas.Está por llover, lleva el paraguas.
'Estar para + infinitive' with weather means 'it's about to' - it's about to rain. Both forms are sometimes used, but 'estar para' is standard with weather.
- Estoy por rendirme con este ejercicio.Estoy para rendirme con este ejercicio.
'Estar por + infinitive' means 'tempted to' or 'inclined to' - I'm tempted to give up.
Common mistakes
Confusing 'estar por' and 'estar para' with infinitives
No estoy por fiestas esta noche.No estoy para fiestas esta noche.'No estar para' means 'not in the mood for.' 'Estar por' with infinitives means 'tempted to' or 'about to do.'
Using 'ser para' when expressing cause
Fue para la lluvia que cancelaron el evento.Fue por la lluvia que cancelaron el evento.'Ser por' expresses cause or reason. 'Ser para' expresses purpose or recipient.
No Preposition Stranding in Spanish
Preposición antes del pronombre relativo
In English, you can leave a preposition at the end of a sentence: 'Who are you talking to?' or 'The house I live in.' In Spanish, this is impossible. The preposition must always come before the question word or relative pronoun: '¿Con quién hablas?' (not '¿Quién hablas con?'), 'La casa en la que vivo' (not 'La casa que vivo en'). This rule applies to all prepositions and is one of the most important structural differences between English and Spanish.
Key rule
Prepositions must always come before the question word or relative pronoun in Spanish; they can never be stranded at the end of a clause.
Examples
- ¿Con quién hablas?¿Quién hablas con?
The preposition 'con' must come before the question word 'quién' - never at the end.
- ¿De dónde eres?¿Dónde eres de?
'De' must precede 'dónde' when asking about origin. Stranding 'de' at the end is impossible.
- La casa en la que vivo es pequeña.La casa que vivo en es pequeña.
In relative clauses, the preposition precedes the article + relative pronoun: 'en la que'.
Common mistakes
Stranding prepositions in questions (English transfer)
¿Quién estás esperando por?¿Por quién estás esperando?Spanish requires the preposition before the question word. Preposition stranding is impossible in Spanish.
Stranding prepositions in relative clauses
La persona que salí con ayer es mi prima.La persona con la que salí ayer es mi prima.In relative clauses, the preposition + article + 'que' must stay together before the clause.
Cleft and Pseudo-Cleft Sentences
Oraciones hendidas y pseudo-hendidas
Spanish uses special sentence structures with 'ser' to emphasize one part of a sentence. A pseudo-cleft starts with 'lo que' and uses 'ser': 'Lo que quiero es descansar' (What I want is to rest). A cleft sentence uses 'ser' + focused element + 'quien/que/donde/cuando': 'Fue María quien lo hizo' (It was María who did it). These constructions let you highlight exactly which piece of information is new or important. They are very common in spoken and written Spanish for adding emphasis or contrast.
Key rule
Use 'lo que... es...' for pseudo-clefts and 'ser + element + quien/donde/cuando' for clefts to emphasize a specific part of the sentence.
Examples
- Lo que quiero es descansar.Lo que quiero es que descanso.
In a pseudo-cleft with an infinitive focus, use the bare infinitive after 'es': 'descansar,' not a clause 'que descanso.'
- Fue María quien lo hizo.Era María quien lo hizo.
For a completed past event, use the preterite 'fue,' not the imperfect 'era,' to match the punctual meaning.
- Es aquí donde vivo.Es aquí que vivo.
For places, use 'donde' in the cleft, not 'que': 'Es aquí donde vivo.'
Common mistakes
Using 'que' instead of 'quien' for people in clefts
Fue Juan que lo dijo.Fue Juan quien lo dijo.When the focused element is a person, use 'quien' or 'el que,' not 'que' alone.
Using 'que' instead of 'donde' for places
Es en Madrid que vivo.Es en Madrid donde vivo.For locations, the relative connector in a cleft is 'donde,' not 'que.'
Topicalization and Fronting
Topicalización y anteposición
In Spanish, you can move a word or phrase to the front of a sentence to make it the topic—what the sentence is about. When you front a direct object, you must add a redundant pronoun: 'A Juan lo vi ayer' (Juan, I saw him yesterday). This is different from English, which doesn't need the extra pronoun. Fronting is very natural in spoken Spanish and signals that the moved element is the topic of discussion. You can also front other elements: 'Eso no lo sabía' (That, I didn't know), 'Lo del accidente, ¿lo supiste?' (The thing about the accident, did you hear about it?).
Key rule
When you move a direct or indirect object to the front of the sentence, you must include a redundant clitic pronoun (lo, la, los, las, le, les) that matches the fronted element.
Examples
- A Juan lo vi ayer en el parque.A Juan vi ayer en el parque.
When the direct object 'a Juan' is fronted, the clitic 'lo' is obligatory: 'A Juan lo vi.'
- Eso no lo sabía.Eso no sabía.
The fronted demonstrative 'eso' (direct object) requires the clitic 'lo': 'Eso no lo sabía.'
- La película la vimos el viernes.La película vimos el viernes.
Fronted feminine direct object 'la película' requires the matching clitic 'la.'
Common mistakes
Omitting the redundant clitic pronoun with fronted objects
A Pedro vi en la calle.A Pedro lo vi en la calle.When a direct object is fronted, the clitic pronoun 'lo' is required to mark its grammatical role.
Using the wrong clitic gender or number
Las flores lo compré ayer.Las flores las compré ayer.The clitic must match the fronted noun: 'las flores' (feminine plural) requires 'las,' not 'lo.'
Adverb Placement in Spanish
Posición de los adverbios
In Spanish, adverbs generally go after the verb they modify: 'Habla bien español' (He speaks Spanish well). Before adjectives and other adverbs, they go directly in front: 'Es muy alto' (He's very tall), 'Corre bastante rápido' (He runs quite fast). Unlike English, you should never place an adverb between an auxiliary verb and a past participle: say 'He comido siempre aquí' (I have always eaten here), not 'He siempre comido aquí.' Some adverbs like 'siempre,' 'nunca,' and 'también' can go before or after the verb for flexibility.
Key rule
Place adverbs after the verb they modify, before adjectives or other adverbs they modify, and never between an auxiliary verb and its participle.
Examples
- Habla bien español.Bien habla español.
Manner adverbs like 'bien' normally follow the verb: 'Habla bien.'
- Es muy alto.Es alto muy.
Degree adverbs like 'muy' go before the adjective: 'muy alto,' not 'alto muy.'
- He comido siempre aquí.He siempre comido aquí.
Never place an adverb between the auxiliary 'he' and the participle 'comido.' Put 'siempre' after the participle.
Common mistakes
Placing adverbs between auxiliary and participle (English influence)
He siempre querido viajar.Siempre he querido viajar.In Spanish, nothing separates the auxiliary 'he' from the participle 'querido.' Move the adverb before the auxiliary or after the participle.
Putting manner adverbs before the verb (English influence)
Bien cocina mi madre.Mi madre cocina bien.Manner adverbs follow the verb in neutral word order: 'cocina bien,' not 'bien cocina.'
Word Order in Subordinate Clauses
Orden de palabras en oraciones subordinadas
In Spanish subordinate clauses (dependent clauses), the word order often differs from main clauses. The subject frequently comes after the verb: 'cuando llegó María' (when María arrived), 'lo que dijo el profesor' (what the teacher said). In embedded questions, the question word moves to the front, and there is no do-support: 'No sé dónde vive' (I don't know where he lives), not 'No sé dónde él vive.' Unlike English, you generally do not place the subject between the question word and the verb: 'No sé qué quieres' (I don't know what you want), not 'No sé qué tú quieres.'
Key rule
In subordinate clauses, the subject typically follows the verb, and in embedded questions, the question word comes directly before the verb with no do-support.
Examples
- No sé dónde vive Juan.No sé dónde Juan vive.
In embedded questions, the subject follows the verb: 'dónde vive Juan,' not 'dónde Juan vive.'
- Cuando llegó María, empezó la fiesta.Cuando María llegó, empezó la fiesta.
In temporal subordinate clauses, the subject naturally follows the verb: 'cuando llegó María.'
- No sé qué quieres.No sé qué tú quieres.
Do not place the subject pronoun between the question word and verb: 'qué quieres,' not 'qué tú quieres.'
Common mistakes
Placing the subject between question word and verb (English influence)
No sé dónde tú vives.No sé dónde vives.In Spanish embedded questions, the subject (especially pronouns) does not go between the question word and the verb. Omit the pronoun or place it after the verb.
Using do-support in embedded questions
No sé qué haces tú hacer.No sé qué haces.Spanish never uses auxiliary verbs for question formation. 'Qué haces' is complete; no do-support is needed.
Passive Voice with Ser
Voz pasiva con ser
Spanish forms the passive voice with 'ser' + past participle: 'El libro fue escrito por Cervantes' (The book was written by Cervantes). The past participle must agree in gender and number with the subject: 'La carta fue escrita' (The letter was written), 'Los edificios fueron construidos' (The buildings were built). The passive is much less common in Spanish than in English. Spanish prefers the active voice or the 'se' passive ('Se habla español'). The 'ser' passive is mostly found in formal writing, news reports, and historical texts.
Key rule
Form the passive with ser + past participle (agreeing in gender and number with the subject), and use 'por' to introduce the agent; prefer active voice or 'se' constructions in everyday speech.
Examples
- El libro fue escrito por Cervantes.El libro fue escribido por Cervantes.
The past participle of 'escribir' is irregular: 'escrito,' not 'escribido.'
- La carta fue escrita por mi abuela.La carta fue escrito por mi abuela.
The participle must agree with the feminine subject 'la carta': 'escrita,' not 'escrito.'
- Los edificios fueron construidos en 1990.Los edificios fue construidos en 1990.
'Ser' must agree with the plural subject: 'fueron construidos,' not 'fue construidos.'
Common mistakes
Failing to make the participle agree with the subject
La canción fue cantado por el coro.La canción fue cantada por el coro.The participle must agree with the feminine subject 'la canción': 'cantada,' not 'cantado.'
Using 'estar' instead of 'ser' for passive actions
La casa está construida por mi padre.La casa fue construida por mi padre.'Estar' + participle describes a state, not an action. Use 'ser' for the passive action: 'fue construida por.'
Reported Speech with Tense Backshift
Estilo indirecto con cambio de tiempos verbales
When reporting what someone said in the past, Spanish shifts verb tenses backward. Present becomes imperfect: 'Dijo que estaba enfermo' (He said he was sick). Preterite becomes pluperfect: 'Dijo que había ido al médico' (He said he had gone to the doctor). Future becomes conditional: 'Dijo que vendría mañana' (He said he would come tomorrow). The word 'que' is always required after the reporting verb: 'Dijo que...' For reported questions, use 'si' for yes/no questions: 'Preguntó si queríamos ir' (He asked if we wanted to go).
Key rule
When the reporting verb is past tense, shift the original verb one step back: present→imperfect, preterite→pluperfect, future→conditional; always include 'que' after the reporting verb.
Examples
- Dijo que estaba enfermo.Dijo que está enfermo.
With a past reporting verb, present 'está' shifts to imperfect 'estaba.'
- Dijo que había ido al médico.Dijo que fue al médico.
Preterite 'fui/fue' shifts to pluperfect 'había ido' in reported speech.
- Dijo que vendría mañana.Dijo que vendrá mañana.
Future 'vendrá' shifts to conditional 'vendría' when the reporting verb is past.
Common mistakes
Forgetting to shift tenses with a past reporting verb
Dijo que tiene hambre.Dijo que tenía hambre.When the reporting verb is in the past ('dijo'), the present tense must shift to imperfect: 'tiene' → 'tenía.'
Omitting 'que' after the reporting verb
Dijo estaba cansado.Dijo que estaba cansado.'Que' is obligatory in Spanish reported speech; it cannot be omitted as English 'that' can.
Concessive Connectors
Conectores concesivos
Concessive connectors introduce an obstacle or contrast that does NOT prevent the main action from happening. The most common ones are 'sin embargo' (however), 'no obstante' (nevertheless), 'a pesar de (que)' (despite/in spite of), and 'aunque' (even though / even if). For example, 'Llovía mucho; sin embargo, salimos' means it was raining a lot, yet we still went out. These connectors let you acknowledge a difficulty while showing that the result was different from what you might expect.
Key rule
Concessive connectors acknowledge an obstacle but show the result is unexpected: 'sin embargo' and 'no obstante' link independent clauses; 'a pesar de (que)' and 'aunque' introduce subordinate clauses.
Examples
- Llovía mucho; sin embargo, salimos a pasear.Llovía mucho; sin embargo salimos a pasear.
'Sin embargo' is followed by a comma when it introduces the main clause after a semicolon.
- No obstante, decidimos continuar con el proyecto.No obstante decidimos continuar con el proyecto.
'No obstante' requires a comma after it when it begins a clause.
- A pesar de la lluvia, fuimos al parque.A pesar la lluvia, fuimos al parque.
'A pesar de' requires the preposition 'de' before the noun; never omit it.
Common mistakes
Combining 'aunque' with 'pero' in the same sentence
Aunque estaba lloviendo, pero fuimos al cine.Aunque estaba lloviendo, fuimos al cine.'Aunque' already introduces the concessive idea; adding 'pero' is redundant and grammatically incorrect.
Omitting 'de' in 'a pesar de'
A pesar el frío, salimos.A pesar del frío, salimos.The fixed expression is 'a pesar de'; 'de' must always be present, and it contracts with 'el' to form 'del'.
Exemplification & Clarification Connectors
Conectores de ejemplificación y aclaración
Exemplification and clarification connectors help you give examples or explain something more clearly. 'Por ejemplo' (for example) introduces a specific case, 'es decir' (that is to say) restates something in simpler terms, 'en particular' (in particular) highlights one item, 'como' (such as) lists examples inside a sentence, and 'en concreto' (specifically) narrows down to a precise detail. These connectors make your speech and writing much clearer and more organized.
Key rule
Use 'por ejemplo' and 'es decir' set off by commas or semicolons; use 'como' (such as) within the sentence flow without extra punctuation.
Examples
- Hay muchas frutas; por ejemplo, manzanas y naranjas.Hay muchas frutas, por ejemplo manzanas y naranjas.
'Por ejemplo' is best preceded by a semicolon (or period) and followed by a comma.
- Es decir, no podemos ir mañana.Es decir no podemos ir mañana.
'Es decir' must be followed by a comma when it begins a clarifying clause.
- Me gustan los deportes, en particular el tenis.Me gustan los deportes en particular el tenis.
'En particular' should be set off by commas to clearly introduce the specific example.
Common mistakes
Omitting the comma after 'por ejemplo'
Hay muchos colores; por ejemplo rojo, azul y verde.Hay muchos colores; por ejemplo, rojo, azul y verde.'Por ejemplo' requires a comma after it to properly introduce the list of examples.
Using 'ejemplo' instead of 'por ejemplo'
Me gustan muchas cosas, ejemplo la música.Me gustan muchas cosas, por ejemplo, la música.The full expression is 'por ejemplo'; 'ejemplo' alone cannot function as a connector.
Reformulation Connectors
Conectores de reformulación
Reformulation connectors help you rephrase what you just said in a different, often clearer or more precise way. 'O sea' (in other words / that is) is very common in spoken Spanish. 'En otras palabras' (in other words) is more formal. 'Mejor dicho' (rather / more precisely) corrects or refines what you said. 'Dicho de otro modo' (put another way) offers an alternative phrasing. These connectors are essential for making yourself understood when your first attempt was not clear enough.
Key rule
Reformulation connectors restate the same idea differently: 'o sea' is informal, 'en otras palabras' is neutral, 'mejor dicho' corrects or refines, and 'dicho de otro modo' offers an alternative phrasing.
Examples
- No vendré; o sea, no cuentes conmigo.No vendré, osea no cuentes conmigo.
'O sea' is two words (not 'osea') and should be set off by punctuation: a semicolon before and a comma after.
- Es inteligente, mejor dicho, es brillante.Es inteligente, mejor dicho es brillante.
'Mejor dicho' should be followed by a comma to separate the correction from the refined statement.
- El proyecto fracasó; en otras palabras, perdimos el dinero invertido.El proyecto fracasó en otras palabras perdimos el dinero invertido.
'En otras palabras' needs a semicolon (or period) before it and a comma after it.
Common mistakes
Writing 'o sea' as one word 'osea'
No puedo ir, osea, no me esperes.No puedo ir; o sea, no me esperes.'O sea' is always written as two separate words. 'Osea' does not exist in standard Spanish (and 'ósea' means 'bone-related').
Using 'o sea' in formal writing where 'es decir' is expected
El PIB se contrajo un 2%; o sea, la economía está en recesión. (in an academic paper)El PIB se contrajo un 2%; es decir, la economía está en recesión.'O sea' is colloquial; in formal or academic writing, 'es decir' or 'en otras palabras' is preferred.
Summary & Conclusion Connectors
Conectores de resumen y conclusión
Summary and conclusion connectors help you wrap up a discussion or text. 'En resumen' (in summary) and 'para resumir' (to sum up) condense everything said before. 'En conclusión' (in conclusion) introduces a final thought. 'En definitiva' (ultimately / in the end) gives the final verdict. 'En fin' (in short / anyway) can signal a summary or a topic change. 'Total que' (so basically) is used in colloquial speech to get to the point. These connectors signal to your listener or reader that you are wrapping up.
Key rule
Summary connectors appear at the start of the final statement and are followed by a comma; use 'en resumen/en conclusión/en definitiva' in formal contexts and 'en fin/total que' in informal speech.
Examples
- En resumen, el proyecto fue un éxito.En resumen el proyecto fue un éxito.
'En resumen' must be followed by a comma when it introduces a summary statement.
- En conclusión, necesitamos mejorar la comunicación.En la conclusión, necesitamos mejorar la comunicación.
'En conclusión' is a fixed expression without an article; do not add 'la'.
- En definitiva, fue la mejor decisión que pudimos tomar.En definitiva fue la mejor decisión que pudimos tomar.
'En definitiva' requires a comma after it to set off the concluding statement.
Common mistakes
Adding an article in 'en conclusión'
En la conclusión, creo que es mejor esperar.En conclusión, creo que es mejor esperar.'En conclusión' is a fixed adverbial expression and does not take the article 'la'.
Putting an accent on 'fin' in 'en fin'
En fín, no importa.En fin, no importa.'Fin' is a monosyllabic word and does not require a written accent in Spanish.
Advanced Sequence Connectors
Conectores de secuencia avanzados
Advanced sequence connectors help you organize your ideas in a clear order, especially in presentations, essays, and structured speech. 'En primer lugar' (firstly), 'en segundo lugar' (secondly), and 'por último' (lastly) create numbered lists. 'Por un lado... por otro lado' (on one hand... on the other hand) presents two sides. 'A continuación' (next) introduces the following point, and 'finalmente' (finally) closes the sequence. These connectors make your speech and writing much more organized.
Key rule
Use 'en primer/segundo lugar' to enumerate points, 'por un lado... por otro lado' to contrast two sides, 'a continuación' for the next step, and 'por último/finalmente' to close the sequence.
Examples
- En primer lugar, debemos analizar los datos.En primer lugar debemos analizar los datos.
'En primer lugar' is followed by a comma to clearly set off the first point.
- En segundo lugar, necesitamos más recursos.En segundo lugar necesitamos más recursos.
'En segundo lugar' requires a comma after it, just like 'en primer lugar'.
- Por un lado, es barato; por otro lado, la calidad no es buena.Por un lado es barato, por otro lado la calidad no es buena.
Both 'por un lado' and 'por otro lado' need commas after them; use a semicolon between the two clauses.
Common mistakes
Mixing 'primero' (basic) with 'en segundo lugar' (advanced)
Primero, vamos a hablar de la economía. En segundo lugar, hablaremos de la política.En primer lugar, vamos a hablar de la economía. En segundo lugar, hablaremos de la política.For consistency, use the same register throughout: either 'primero/segundo' (informal) or 'en primer lugar/en segundo lugar' (formal).
Using 'por un lado' without completing with 'por otro lado'
Por un lado, el proyecto es interesante. También es difícil.Por un lado, el proyecto es interesante; por otro lado, es difícil.'Por un lado' sets up an expectation for 'por otro lado'; failing to complete the pair leaves the structure incomplete.
Opinion Markers
Marcadores de opinión
Opinion markers let you clearly signal that what you are about to say is your personal view. 'En mi opinión' (in my opinion) and 'desde mi punto de vista' (from my point of view) are neutral and formal. 'Creo que' (I think that) and 'me parece que' (it seems to me that) are everyday expressions. 'A mi juicio' (in my judgment) is more formal. 'Para mí' (for me) is the simplest and most conversational. These markers are essential for debates, discussions, and expressing preferences politely.
Key rule
'Creo que' and 'me parece que' take indicative in affirmative sentences but subjunctive when negated; prepositional phrases like 'en mi opinión', 'para mí', and 'a mi juicio' are set off by commas.
Examples
- En mi opinión, es la mejor solución.En mi opinión es la mejor solución.
'En mi opinión' must be followed by a comma to set off the opinion marker.
- Me parece que tiene razón.Me parece de que tiene razón.
'Parecer que' does not take 'de' before 'que'; adding 'de' is a common error known as 'dequeísmo'.
- Creo que deberíamos hablar con ella.Creo de que deberíamos hablar con ella.
'Creer que' does not take 'de'; 'creo de que' is an incorrect use of 'dequeísmo'.
Common mistakes
Dequeísmo: adding 'de' before 'que' with 'creer' and 'parecer'
Creo de que es importante estudiar.Creo que es importante estudiar.'Creer que' and 'parecer que' never take 'de' before 'que'; this error is called 'dequeísmo'.
Confusing 'para mí' (opinion) with 'por mí' (cause/indifference)
Por mí, este restaurante es el mejor de la ciudad.Para mí, este restaurante es el mejor de la ciudad.'Para mí' means 'in my opinion'; 'por mí' means 'because of me' or 'as far as I'm concerned / I don't mind'.
Systematic Accentuation Rules
Reglas de acentuación sistemática
Spanish words are classified by where the stress falls: agudas (last syllable), llanas/graves (penultimate syllable), esdrújulas (antepenultimate syllable), and sobresdrújulas (before the antepenultimate). Each category has clear rules about when a written accent (tilde) is required. Mastering these rules lets you correctly accent any Spanish word, not just memorize individual cases. Additionally, the tilde diacrítica distinguishes pairs of words that sound alike but have different meanings and grammatical functions.
Key rule
Agudas get an accent if ending in vowel/N/S; llanas get an accent if NOT ending in vowel/N/S; esdrújulas and sobresdrújulas ALWAYS get an accent.
Examples
- La canción es muy bonita.La cancion es muy bonita.
'Canción' is aguda (stress on last syllable) ending in N, so it requires an accent.
- El árbol está en el jardín.El arbol está en el jardin.
'Árbol' is llana ending in L (not vowel/N/S), so it needs an accent. 'Jardín' is aguda ending in N, so it also needs an accent.
- El teléfono está sonando.El telefono está sonando.
'Teléfono' is esdrújula (stress on te-LÉ-fo-no), so it always carries an accent.
Common mistakes
Adding an accent to llanas ending in vowel/N/S
El exámen es difícil.El examen es difícil.'Examen' is llana ending in N, so by rule it does NOT carry an accent. The stress is natural on the penultimate syllable.
Forgetting the accent on agudas ending in vowel/N/S
La leccion es sobre la nacion.La lección es sobre la nación.Both 'lección' and 'nación' are agudas ending in N, so they must carry an accent.
G vs J Spelling Rules
Distinción ortográfica entre G y J
In Spanish, G and J can make the same harsh sound before E and I, but they follow different spelling rules. G before E or I sounds like the Spanish J (gente, girar). To get a hard G sound before E or I, you need a silent U: gue (guerra), gui (guiar). If you want the U to be pronounced, you add a diéresis: güe (pingüino), güi (vergüenza). J always makes the harsh sound regardless of the vowel that follows. Some common words use J before E and I instead of G, and these must be memorized.
Key rule
G before e/i sounds like J; use 'gue/gui' for a hard G before e/i, 'güe/güi' when the U is pronounced; J always makes the harsh sound with any vowel.
Examples
- La gente es muy amable.La jente es muy amable.
'Gente' is spelled with G, even though ge- sounds like je-. This word comes from Latin and keeps the G.
- La guerra terminó hace años.La gerra terminó hace años.
'Guerra' needs the silent U (gue) to produce the hard G sound before E.
- El pingüino vive en el frío.El pinguino vive en el frío.
'Pingüino' needs the diéresis (güi) because the U is pronounced: pin-GWI-no.
Common mistakes
Writing J for G before e/i in established words
La jente viaja en el coche.La gente viaja en el coche.'Gente' is etymologically spelled with G. Many common words use G before e/i: gente, general, gesto, girar, gigante.
Forgetting the silent U in gue/gui
La gerra es terrible. Toca la gitarra.La guerra es terrible. Toca la guitarra.To produce a hard G before e/i, you must include the silent U: guerra, guitarra, guiar.
LL vs Y Spelling Rules
Distinción ortográfica entre LL e Y
In most Spanish-speaking regions, LL and Y are pronounced the same way (this is called yeísmo). Since they sound identical, you need spelling rules to know which to use. LL appears in diminutive endings like -illo/-illa (amarillo, silla), and in common patterns like -lla/-llo/-lle (calle, caballo, estrella). Y is used as the conjunction 'and,' at the end of words (hoy, rey, ley), and in certain verb forms like gerunds of verbs whose stem ends in a vowel (leyendo, cayendo). Some word pairs are easily confused: halla/haya, valla/vaya, calló/cayó.
Key rule
LL appears in diminutives (-illo/-illa) and common word patterns (-lla/-llo/-lle); Y is used as 'and,' at the end of words, and in verb forms where a vowel-ending stem meets an i-sound.
Examples
- La calle está llena de gente.La caye está yena de gente.
'Calle' uses LL (-lle pattern). 'Llena' starts with LL (from Latin 'plenus').
- El amarillo es mi color favorito.El amarilo es mi color favorito.
'Amarillo' uses LL in the -illo diminutive suffix.
- Hoy es un día muy bonito.Holl es un día muy bonito.
'Hoy' ends in Y, as do all words where the final sound is an unstressed 'i': hoy, rey, ley.
Common mistakes
Confusing cayó and calló
El niño se calló de la bicicleta.El niño se cayó de la bicicleta.'Cayó' (fell, from caer) uses Y. 'Calló' (fell silent, from callar) uses LL. Falling = cayó; going silent = calló.
Confusing halla and haya
Espero que halla una solución.Espero que haya una solución.'Haya' (subjunctive of haber) uses Y. 'Halla' (finds, from hallar) uses LL.
Hedging and Softening
Atenuación y suavización del discurso
Hedging means softening what you say so you don't sound too direct or forceful. Spanish has many ways to hedge: expressions like 'creo que' (I think), 'me parece que' (it seems to me), 'quizás' (maybe), 'tal vez' (perhaps), and 'a lo mejor' (maybe). You can also use the conditional tense to sound more polite: '¿Podrías ayudarme?' instead of '¿Puedes ayudarme?'. Hedging is essential for polite disagreement, making suggestions, and sounding natural in conversation.
Key rule
Use hedging expressions like 'creo que,' 'quizás,' 'a lo mejor,' and the conditional tense to soften statements, opinions, and requests in Spanish.
Examples
- Creo que deberíamos salir más temprano.Debemos salir más temprano.
'Creo que' + conditional softens the suggestion. The direct version sounds like an order.
- ¿Podrías ayudarme con esto?Ayúdame con esto.
Using the conditional '¿Podrías...?' is much more polite than the imperative.
- Quizás tengamos que cambiar de plan.Tenemos que cambiar de plan.
'Quizás' + subjunctive hedges the statement, making it less absolute.
Common mistakes
Using indicative after 'puede que'
Puede que viene mañana.Puede que venga mañana.'Puede que' always requires the subjunctive: venga, llueva, sea, tenga.
Using subjunctive after 'a lo mejor'
A lo mejor venga Pedro.A lo mejor viene Pedro.'A lo mejor' always takes the indicative, unlike 'quizás' or 'tal vez' which can take either.
Academic vs Conversational Register
Registro académico frente a coloquial
Spanish, like English, has different levels of formality. In academic or formal writing, you use words like 'realizar' (to carry out) instead of 'hacer' (to do), 'sin embargo' instead of 'pero,' and 'debido a' instead of 'por.' In conversation, the simpler words are perfectly fine. Knowing when to use each register is key to sounding appropriate. Formal writing also avoids colloquial fillers and uses more complex sentence structures.
Key rule
Formal/academic Spanish uses elevated vocabulary (realizar, sin embargo, debido a, mediante), impersonal constructions, and complex sentences; conversational Spanish uses simpler words (hacer, pero, por, con) and fillers.
Examples
- Se realizó un estudio exhaustivo. (formal)Hicimos un estudio muy completo. (in an academic paper)
Academic writing prefers 'realizar' over 'hacer' and passive/impersonal constructions over first person.
- Sin embargo, los resultados no fueron concluyentes.Pero los resultados no fueron concluyentes. (in a formal report)
'Sin embargo' is the formal equivalent of 'pero' and is preferred in academic texts.
- Debido a la falta de recursos, se canceló el proyecto.Por la falta de recursos, se canceló el proyecto. (in a formal letter)
'Debido a' is the formal version of 'por' when expressing cause.
Common mistakes
Using informal language in academic writing
Bueno, pues hicimos el experimento y nos salió bien.Se llevó a cabo el experimento y se obtuvieron resultados satisfactorios.Academic writing requires formal vocabulary, impersonal constructions, and no conversational fillers.
Using overly formal language in casual conversation
Deseo manifestar que no obstante mis esfuerzos, no logré realizar la tarea.Mira, es que intenté hacerlo pero no pude.Using academic register in casual contexts sounds unnatural, pompous, and socially awkward.
Common Spanish Collocations
Colocaciones comunes del español
Collocations are word combinations that native speakers use naturally, even when a different combination might seem logical. In Spanish, many collocations differ from English: you 'take a decision' (tomar una decisión), not 'make' one; you 'make a question' (hacer una pregunta), not 'ask' one; you 'give a walk' (dar un paseo), not 'take' one. Learning these fixed combinations is essential for sounding natural in Spanish.
Key rule
Spanish collocations often use different verbs than their English equivalents: learn 'tomar una decisión,' 'hacer una pregunta,' 'dar un paseo,' and 'prestar atención' as fixed combinations.
Examples
- Tengo que tomar una decisión importante.Tengo que hacer una decisión importante.
In Spanish, decisions are 'taken' (tomar una decisión), not 'made.' 'Hacer una decisión' is a calque from English.
- El profesor hizo una pregunta difícil.El profesor preguntó una pregunta difícil.
In Spanish, questions are 'made' (hacer una pregunta). 'Preguntar una pregunta' is redundant.
- La reunión tendrá lugar el lunes.La reunión tomará lugar el lunes.
'Tener lugar' means 'to take place.' 'Tomar lugar' is an English calque.
Common mistakes
Translating 'make a decision' literally
Necesito hacer una decisión.Necesito tomar una decisión.Spanish uses 'tomar' (take), not 'hacer' (make), with 'decisión.' This is one of the most common English interference errors.
Saying 'pagar atención' instead of 'prestar atención'
Debes pagar atención en clase.Debes prestar atención en clase.'Prestar' (lend) is used with 'atención.' 'Pagar' means to pay money, not to pay attention.
Diminutives and Augmentatives
Diminutivos y aumentativos
Spanish uses special endings to modify nouns and adjectives. Diminutives like -ito/-ita make things small or express affection (casita = little house, perrito = little dog). Augmentatives like -ote/-ota and -azo/-aza make things big or add emphasis (grandote = really big, golazo = amazing goal). These suffixes are extremely common in everyday Spanish and convey emotion, affection, or intensity. There are spelling rules to follow, and some diminutives have become standalone words with their own meaning.
Key rule
Add -ito/-ita for smallness/affection, -illo/-illa for a quaint/diminished quality, -ote/-ota or -azo/-aza for bigness/emphasis; watch for spelling changes like z→c before -ito.
Examples
- ¡Qué casita tan bonita!¡Qué casa pequeña tan bonita!
'Casita' (casa + -ita) expresses both smallness and affection more naturally than 'casa pequeña.'
- El perrito está dormido en el sofá.El perro pequeñito está dormido en el sofá.
'Perrito' (perro + -ito) is the natural way to say 'little dog' with affection.
- Dame un pedacito de pastel.Dame un pedazito de pastel.
When adding -ito to words ending in -z, the Z changes to C: pedazo → pedacito.
Common mistakes
Forgetting the z→c spelling change before -ito
Dame un pedazito de pan.Dame un pedacito de pan.Before -ito/-ita, the letter Z changes to C: pedazo → pedacito, taza → tacita, lápiz → lapicito.
Using -ito directly on monosyllables instead of -cito
Quiero un panito, por favor.Quiero un pancito, por favor.Monosyllabic words and words ending in -n or -r typically add -cito, not just -ito: pan → pancito, flor → florecita.
Word Formation with Suffixes
Formación de palabras con sufijos
Spanish uses suffixes to create new words from existing ones. Adding -ción or -sión to verb stems creates nouns (comunicar → comunicación, decidir → decisión). Adding -mente to the feminine form of an adjective creates an adverb (rápida → rápidamente). Other common suffixes include -oso/-osa for adjectives, -ero/-era and -ista for professions, and -dad/-tad for abstract qualities. Learning these patterns helps you expand your vocabulary quickly.
Key rule
Suffixes like -ción/-sión (nouns), -mente (adverbs), -oso (adjectives), -ero/-ista (professions), and -dad (qualities) systematically create new words from existing roots.
Examples
- La comunicación es importante en el trabajo.La comunicamento es importante en el trabajo.
The verb 'comunicar' forms its noun with -ción: comunicación, not an invented suffix.
- Ella habla rápidamente.Ella habla rápidomente.
Adverbs with -mente are formed from the feminine adjective: rápida + -mente = rápidamente, not from the masculine form.
- Este camino es peligroso.Este camino es peligrón.
The adjective meaning 'dangerous' uses the suffix -oso: peligro → peligroso.
Common mistakes
Forming -mente adverbs from masculine adjective
Él camina lento → Él camina lentomente.Él camina lentamente.Adverbs ending in -mente are formed from the feminine form of the adjective: lenta + -mente = lentamente.
Changing the gender of -ista nouns
Él es un periodisto.Él es un periodista.Nouns ending in -ista do not change form for gender. Both masculine and feminine use -ista: el periodista, la periodista.
Todo/a/os/as as Determiner
Todo/a/os/as como determinante
In Spanish, 'todo' (all/every) must agree in gender and number with the noun it modifies: todo, toda, todos, todas. When used with a specific noun, it requires the definite article after it: 'todo el día' (all day), 'toda la noche' (all night), 'todos los días' (every day), 'todas las semanas' (every week). Omitting the article is a very common mistake. 'Cada' is an alternative for 'every' that does NOT need an article: 'cada día.'
Key rule
Todo/a/os/as requires the definite article before the noun — say 'todo el día' and 'todos los días,' never 'todo día' or 'todos días.'
Examples
- He estudiado todo el día.He estudiado todo día.
Todo requires the definite article 'el' before the noun: 'todo el día,' not 'todo día.'
- Toda la familia vino a cenar.Toda familia vino a cenar.
Toda requires 'la' before the noun: 'toda la familia.'
- Todos los estudiantes aprobaron.Todos estudiantes aprobaron.
Todos requires 'los' before the noun: 'todos los estudiantes.'
Common mistakes
Omitting the article after todo/a/os/as
Trabajo todos días.Trabajo todos los días.Todo/a/os/as requires the definite article (el, la, los, las) between it and the noun.
Adding an article after cada
Cada la semana voy al gimnasio.Cada semana voy al gimnasio.'Cada' is invariable and never takes an article. It directly precedes the noun.
Indefinite Determiners: Cualquier, Alguno, Ninguno
Determinantes indefinidos: cualquier, alguno, ninguno
Spanish has several indefinite determiners. 'Cualquier' (any) loses its final -a before a noun: 'cualquier libro' but 'un libro cualquiera.' 'Alguno' (some) shortens to 'algún' before masculine singular nouns: 'algún problema.' 'Ninguno' (no/none) shortens to 'ningún' the same way: 'ningún problema.' Ninguno is almost always singular and appears in double negatives: 'No hay ningún problema.' These words help express indefinite or negative quantities.
Key rule
Cualquier, algún, and ningún are shortened forms used before nouns; ninguno requires double negation with 'no' and is always singular.
Examples
- Puedes elegir cualquier libro.Puedes elegir cualquiera libro.
Before a noun, 'cualquiera' shortens to 'cualquier': cualquier libro.
- Es una persona cualquiera.Es una persona cualquier.
After the noun, the full form 'cualquiera' is used: una persona cualquiera.
- ¿Tienes algún problema?¿Tienes alguno problema?
Before a masculine singular noun, 'alguno' shortens to 'algún': algún problema.
Common mistakes
Using full form cualquiera before a noun
Cualquiera día voy a visitarte.Cualquier día voy a visitarte.Before a noun, 'cualquiera' must shorten to 'cualquier,' regardless of gender.
Using plural form of ninguno
No tengo ningunos libros.No tengo ningún libro.'Ninguno' is almost always singular in modern Spanish. Use 'ningún libro' (singular) even when referring to plural concepts.
Percentages and Fractions
Porcentajes y fracciones
Percentages in Spanish use 'el ... por ciento' or the % symbol: 'el cincuenta por ciento' (50%). Verb agreement with percentage subjects can be singular or plural: 'El 30% de los estudiantes aprobó' or 'aprobaron' — both are accepted. For fractions, use 'medio/a' (half), 'tercio' (third), 'cuarto' (quarter), and 'quinto' (fifth). 'La mitad de' means 'half of,' 'un tercio de' means 'a third of.' The word 'medio' agrees in gender: 'media hora' (half an hour).
Key rule
Percentages use 'el + number + por ciento' and can take singular or plural verbs; fractions use 'medio/a' (half), 'tercio' (third), 'cuarto' (quarter); and 'medio' agrees in gender with its noun.
Examples
- El 50% de la población vive en ciudades.50% de la población vive en ciudades.
Percentages typically take the definite article 'el': 'el 50% de la población.'
- El treinta por ciento de los alumnos aprobó.Los treinta por ciento de los alumnos aprobaron.
The article before a percentage is always 'el' (singular), never 'los.' The verb can be singular or plural.
- Necesito media hora para terminar.Necesito medio hora para terminar.
'Hora' is feminine, so 'medio' must agree: 'media hora.'
Common mistakes
Omitting the article before percentages
20% de los votos fueron para él.El 20% de los votos fueron para él.In Spanish, percentages typically take the definite article 'el' before the number.
Wrong gender agreement with medio/a
Necesito medio hora más.Necesito media hora más.'Hora' is feminine, so 'medio' must become 'media' to agree: media hora.
Large Numbers: Thousands, Millions, Billions
Números grandes: miles, millones, billones
In Spanish, 'mil' means 1,000 and is never preceded by 'un': say 'mil personas,' not 'un mil personas.' For multiples, say 'dos mil,' 'diez mil,' etc. 'Millón' (1,000,000) IS preceded by 'un': 'un millón.' Crucially, 'millón' requires 'de' before a noun: 'un millón de personas,' not 'un millón personas.' Be careful: 'billón' in Spanish means one trillion (1,000,000,000,000), NOT one billion! One billion in Spanish is 'mil millones.' Spain uses periods for thousands: 1.000.000.
Key rule
Never say 'un mil' — just 'mil'; always say 'un millón DE + noun'; and remember that Spanish 'billón' means trillion, not billion (billion = mil millones).
Examples
- Hay mil estudiantes en la escuela.Hay un mil estudiantes en la escuela.
'Mil' is never preceded by 'un.' Say 'mil estudiantes,' not 'un mil estudiantes.'
- La ciudad tiene un millón de habitantes.La ciudad tiene un millón habitantes.
'Millón' requires 'de' before a noun: 'un millón de habitantes.'
- Tres millones de personas viven aquí.Tres millones personas viven aquí.
'Millones' also requires 'de' before a noun: 'tres millones de personas.'
Common mistakes
Adding 'un' before mil
Tengo un mil razones para quedarme.Tengo mil razones para quedarme.'Mil' is never preceded by 'un' in Spanish. Simply say 'mil.'
Omitting 'de' after millón/millones before a noun
Ganó dos millones euros.Ganó dos millones de euros.'Millón/millones' requires the preposition 'de' before a noun: 'millones de euros.'
Approximate Quantities
Cantidades aproximadas
Spanish has many ways to express approximate quantities. 'Unos/unas' before a number means 'about': 'unas veinte personas' (about twenty people). Other expressions include 'alrededor de' (around), 'aproximadamente' (approximately), 'más o menos' (more or less), 'casi' (almost), 'cerca de' (close to), and the colloquial 'como' (about: 'como cien personas'). A fun expression is 'y pico,' meaning 'and a bit': 'treinta y pico' (thirty-something).
Key rule
Use 'unos/unas' before numbers for 'about,' 'y pico' after round numbers for 'and a bit,' and choose among alrededor de, casi, cerca de, más o menos, or como depending on formality.
Examples
- Había unas veinte personas en la fiesta.Había un veinte personas en la fiesta.
'Unas' (feminine, agreeing with 'personas') before the number means 'about': unas veinte personas.
- El viaje dura aproximadamente tres horas.El viaje dura aproximado tres horas.
Use the adverb 'aproximadamente' (approximately), not the adjective 'aproximado.'
- Casi mil personas asistieron al concierto.Casi mil de personas asistieron al concierto.
'Casi' directly precedes the number without 'de': 'casi mil personas.'
Common mistakes
Wrong gender agreement with unos/unas
Vinieron unos treinta personas.Vinieron unas treinta personas.'Personas' is feminine, so the approximation marker must also be feminine: 'unas treinta personas.'
Confusing y pico with y poco
Tiene cuarenta y poco años.Tiene cuarenta y pico años.'Y pico' (and a bit) is the correct expression for approximate quantities above a round number. 'Y poco' means 'and little' and has a different meaning.
