Lenguia | B1 Croatian Grammar: 63 Topics & Examples

In Croatian, adding a prefix to an imperfective verb almost always makes it perfective, but the prefix usually also adds a layer of meaning. From the base verb pisati (to write, imperfective), na- gives napisati (to write up, finish writing), pre- gives prepisati (to copy out / rewrite), pot- gives potpisati (to sign), za- gives zapisati (to jot down). Sometimes the prefix only perfectivises with no real meaning change, and then it is called the 'pure' perfectivising prefix for that verb (often na- for pisati). The trick at this level is to feel which prefixes just close off the action and which ones genuinely change what the verb means.

Key rule

A prefix on an imperfective verb makes it perfective and usually also adds a directional or modal meaning; only the conventional 'pure' prefix perfectivises without changing the core meaning.

Examples

Moram napisati pismo do petka.
Moram pisati pismo do petka.
With a deadline the action is bounded and completed, so the perfective napisati is needed; pisati would only describe the process.
Učenik je prepisao tekst iz knjige u bilježnicu.
Učenik je napisao tekst iz knjige u bilježnicu.
pre- means copying across; napisao would mean he authored it, not copied it.
Brzo sam zapisao broj telefona.
Brzo sam pisao broj telefona.
za- gives the quick, bounded sense of jotting down; the bare imperfective pisao describes ongoing writing, not a quick note.

Common mistakes

Leaving the verb imperfective when the action is clearly completed
Jučer sam pisao zadaću i predao je.
Jučer sam napisao zadaću i predao je.
A finished, handed-in homework is a bounded result, which requires the perfective napisati.
Choosing a meaningful prefix instead of the pure perfectivising one
Konačno sam zapisao roman.
Konačno sam napisao roman.
za- means 'jot down'; the neutral perfective of 'finish writing' a whole novel is napisati.

Secondary Imperfectives (-ava-/-iva-/-va-)

Sekundarna imperfektivizacija (-ava-, -iva-)

Once a prefix has made a verb perfective, Croatian can turn it back into an imperfective by adding a suffix, usually -ava-, -iva- or -va-. So prepisati (perfective, copy out) becomes prepisivati (imperfective, be copying out), dati (give, perfective) becomes davati (be giving), kupiti (buy) becomes kupovati. This 'secondary imperfective' lets you talk about a prefixed action as an ongoing process or a habit. The suffix often changes the stem and shifts the stress, so you have to learn the new present tense (prepisujem, dajem, kupujem). This is how Croatian builds full aspect pairs around prefixed verbs.

Key rule

Add -ava-/-iva-/-va- to a prefixed perfective to build its imperfective partner, adjusting the stem and learning the new (often -ujem) present tense.

Examples

Svaki dan prepisujem bilješke s ploče.
Svaki dan prepišem bilješke s ploče.
Svaki dan marks repetition, so the secondary imperfective prepisivati (prepisujem) is required, not the perfective prepisati.
Baka mi je uvijek davala slatkiše.
Baka mi je uvijek dala slatkiše.
uvijek (always) signals habitual action, so the secondary imperfective davati (davala) is needed, not the single-event dati.
Trgovina prodaje voće i povrće.
Trgovina proda voće i povrće.
An ongoing business activity uses the imperfective prodavati (prodaje); prodati would mean a single completed sale.

Common mistakes

Using the prefixed perfective for a habitual action
Svako jutro prepišem lekciju.
Svako jutro prepisujem lekciju.
Habitual repetition requires the secondary imperfective prepisivati (prepisujem).
Wrong present-tense stem of the secondary imperfective
Ja prodavam stan.
Ja prodajem stan.
prodavati conjugates as prodajem in the present, not prodavam.

B1Aspect

Suppletive & Irregular Aspect Pairs (reći/govoriti, uzeti/uzimati)

Supletivni i nepravilni vidski parovi

Most aspect pairs are built tidily with a prefix or a suffix, but some of the commonest verbs do not follow a regular pattern. Their two aspects come from different stems or even different roots. You simply have to learn them as pairs: reći (perfective, to say) goes with govoriti or kazivati for the imperfective; uzeti (take, perfective) with uzimati (imperfective); staviti (put) with stavljati; doći (come) with dolaziti; sjesti (sit down) with sjedati. Because these verbs are so frequent, mixing up the aspect is very noticeable. Treat each pair as a single vocabulary item with two halves.

Key rule

Some frequent verbs form aspect partners from different stems or roots (reći/govoriti, uzeti/uzimati, doći/dolaziti) and must be memorised as fixed pairs rather than derived.

Examples

Rekao mi je istinu.
Govorio mi je istinu jednom.
A single completed telling uses the perfective reći (rekao); govoriti is the ongoing 'speak' and clashes with jednom.
Često mi je govorio o ratu.
Često mi je rekao o ratu.
često signals repetition, so the imperfective govoriti is required, not the single-event reći.
Uzeo sam ključeve i izašao.
Uzimao sam ključeve i izašao.
A single completed action of taking uses the perfective uzeti (uzeo); uzimati is the repeated/ongoing version.

Common mistakes

Using govoriti for a single act of telling
Govorio mi je gdje je ključ.
Rekao mi je gdje je ključ.
A one-off act of telling specific information is the perfective reći (rekao).
Using reći for ongoing speaking
Dok mi je rekao priču, zaspao sam.
Dok mi je govorio priču, zaspao sam.
An ongoing background of speaking needs the imperfective govoriti.

B1Aspect

Biaspectual Verbs (ručati, telefonirati, čuti)

Dvovidni glagoli

A few Croatian verbs are biaspectual: a single form works as both perfective and imperfective, and only the context tells you which reading is meant. Common ones are ručati (to have lunch), večerati (to have dinner), telefonirati (to phone), organizirati (to organise), and čuti and vidjeti (to hear, to see). So ručam can mean 'I am having lunch' (process) or, with a time word, 'I will have lunch' as a completed event. Many borrowed verbs in -irati behave this way. You read the aspect from time adverbials and the surrounding clause rather than from the verb's shape.

Key rule

Biaspectual verbs (ručati, telefonirati, čuti and most -irati loanwords) have one form for both aspects; the surrounding context, not the verb shape, fixes the reading.

Examples

Upravo ručam, nazvat ću te poslije.
Upravo izručavam, nazvat ću te poslije.
ručati is biaspectual; you do not invent a derived imperfective like *izručavam — context (upravo) gives the ongoing reading.
Jučer smo ručali u tri sata.
Jučer smo doručali u tri sata.
The same form ručati covers the completed reading; *doručati is not a standard verb for finishing lunch.
Telefonirao sam mu cijelo jutro.
Telefoniravao sam mu cijelo jutro.
telefonirati is biaspectual; cijelo jutro gives the durative reading without a derived form like *telefoniravati.

Common mistakes

Inventing a secondary imperfective for a biaspectual verb
Telefoniravao sam joj satima.
Telefonirao sam joj satima.
telefonirati is biaspectual; the same form covers the durative reading, so no derived imperfective exists.
Inventing a prefixed perfective for a biaspectual verb
Brzo sam izručao i otišao.
Brzo sam ručao i otišao.
ručati already covers the perfective reading with brzo; *izručati is not standard.

B1Aspect

Aspect in the Future Tenses (futur I & II)

Vid u futuru

Croatian aspect runs through the future just as it runs through the past. In futur I, the perfective presents the future action as a single completed event (Napisat ću pismo = I'll write the letter and finish it), while the imperfective presents it as a process or habit (Pisat ću pismo = I'll be writing the letter / I'll write letters). Futur II (a relative future used mostly in clauses with kad, ako, čim) follows the same logic: a perfective in futur II means 'will have done', an imperfective means 'will be doing'. So choosing aspect in the future is about whether you mean a bounded result or an ongoing/repeated situation.

Key rule

Pick perfective in the future for a single completed result and imperfective for a process or habit; in futur II the perfective means 'will have done' before the main clause.

Examples

Napisat ću pismo do večeras.
Pisat ću pismo do večeras.
do večeras sets a completion point, so the perfective napisati is needed; the imperfective pisati only describes the process.
Cijeli vikend ću čitati.
Cijeli vikend ću pročitati.
cijeli vikend frames a duration, which requires the imperfective čitati, not the bounded perfective pročitati.
Sutra ću napisati izvještaj i poslati ga.
Sutra ću pisati izvještaj i poslati ga.
The result (and then sending it) needs the perfective napisati; pisati leaves the report unfinished.

Common mistakes

Using the imperfective future for a bounded result
Do sutra ću pisati esej.
Do sutra ću napisati esej.
do sutra sets a completion deadline, which requires the perfective napisati.
Using the perfective future for a duration
Cijelu noć ću pročitati.
Cijelu noć ću čitati.
cijelu noć frames an ongoing process, so the imperfective čitati is needed.

B1Aspect

Aspect in the Conditional

Vid u kondicionalu

The conditional (kondicional), formed with the bih-clitics plus the past participle (čitao bih, napisao bih), also distinguishes aspect. The imperfective conditional describes a hypothetical process, habit, or willingness (Čitao bih cijeli dan = I would read / be reading all day), while the perfective conditional describes a single completed hypothetical result (Pročitao bih tu knjigu = I would read that book and finish it). The same completion-versus-process test you use elsewhere applies. The conditional is also used for polite requests, and there the aspect still follows the meaning: a one-off favour is usually perfective.

Key rule

In the conditional, use the imperfective for a hypothetical process, habit, or willingness, and the perfective for a single completed hypothetical result.

Examples

Da imam vremena, pročitao bih cijeli roman.
Da imam vremena, čitao bih cijeli roman.
Reading the whole novel to completion is a bounded result, requiring the perfective pročitati in the conditional.
Svaki dan bih trčao da nije ovako hladno.
Svaki dan bih otrčao da nije ovako hladno.
svaki dan marks a habit, so the imperfective trčati is used; the perfective otrčati implies a single completed run.
Rado bih ti pomogao s prijevodom.
Rado bih ti pomagao s prijevodom jednom.
A single offered favour uses the perfective pomoći; pomagati would imply repeated, ongoing help, clashing with jednom.

Common mistakes

Using the imperfective conditional for a single completed result
Da mogu, čitao bih tu knjigu do kraja.
Da mogu, pročitao bih tu knjigu do kraja.
do kraja signals completion, so the perfective pročitati is needed.
Using the perfective conditional for a habit
Svaki dan bih otrčao deset kilometara.
Svaki dan bih trčao deset kilometara.
svaki dan marks repetition, requiring the imperfective trčati.

B1Aspect

Aspect under Negation (Nisam pisao vs Nisam napisao)

Vid u negaciji

Negation interacts with aspect in a meaningful way. Negating an imperfective verb usually says the action did not happen at all or was not going on (Nisam pisao = I wasn't writing / I didn't write at all). Negating a perfective verb usually says you tried or were expected to but did not manage to complete it (Nisam napisao = I didn't finish writing / I didn't get it written). So the imperfective negation denies the activity, while the perfective negation denies the result. This is why a learner saying Nisam napisao can sound like 'I failed to finish' rather than 'I didn't write', which is often not what they mean.

Key rule

Negate the imperfective to deny that an activity happened or was ongoing; negate the perfective to say a specific expected result was not completed.

Examples

Nisam pisao cijeli dan, samo sam se odmarao.
Nisam napisao cijeli dan, samo sam se odmarao.
Denying any writing activity over a duration uses the imperfective negative nisam pisao; the perfective would oddly deny completing a single text 'all day'.
Nisam napisao zadaću, nije mi ostalo vremena.
Nisam pisao zadaću, nije mi ostalo vremena.
Failing to complete the expected homework uses the perfective negative nisam napisao; nisam pisao would just say you weren't writing it.
Nikad nisam pušio.
Nikad nisam zapušio.
Denying the habit/activity over a lifetime uses the imperfective negative; the perfective would deny a single completed instance, which is the wrong meaning.

Common mistakes

Using negated perfective to deny an activity outright
Nisam napisao ništa cijeli dan jer nisam htio raditi.
Nisam pisao ništa cijeli dan jer nisam htio raditi.
Denying that any writing went on over a duration uses the imperfective negative nisam pisao.
Using negated imperfective for a failed expected result
Nisam pisao izvještaj, pa me šef grdio.
Nisam napisao izvještaj, pa me šef grdio.
Failing to complete the expected report uses the perfective negative nisam napisao.

B1Aspect

Iterative vs Semelfactive (kucati vs kucnuti)

Učestali i trenutni glagoli

Beyond the basic perfective/imperfective split, Croatian marks a finer contrast for some action verbs. A semelfactive verb names a single, instantaneous occurrence of an action and is formed with the suffix -nu-: kucnuti (knock once), skočiti (jump once), gurnuti (give a push), mahnuti (give a wave), pljesnuti (give a clap). It is perfective. Its imperfective partner is iterative — it names the action as a repeated series: kucati (be knocking / keep knocking), skakati (be jumping), gurati (be pushing), mahati (be waving). So kucnuo je na vrata is one knock, while kucao je na vrata is repeated knocking. This is an Aktionsart distinction layered on top of aspect.

Key rule

Use the -nu- semelfactive (kucnuti, skočiti, mahnuti) for a single instantaneous action and its iterative imperfective base (kucati, skakati, mahati) for repeated or ongoing action.

Examples

Netko je kucnuo na vrata i ja sam otvorio.
Netko je kucao na vrata i ja sam odmah otvorio na prvo kucanje.
A single knock followed by opening is the semelfactive kucnuti; the iterative kucao describes repeated knocking, clashing with 'on the first knock'.
Kucao je na vrata nekoliko minuta, ali nitko nije otvorio.
Kucnuo je na vrata nekoliko minuta, ali nitko nije otvorio.
Repeated knocking over minutes needs the iterative kucati; the punctual kucnuti cannot take a duration like nekoliko minuta.
Dijete je skočilo u bazen.
Dijete je skakalo u bazen jednom.
A single jump is the semelfactive skočiti; the iterative skakati means jumping repeatedly and clashes with jednom.

Common mistakes

Using the semelfactive with a duration adverbial
Kucnuo je na vrata pet minuta.
Kucao je na vrata pet minuta.
The -nu- semelfactive is punctual and incompatible with duration; repeated knocking needs the iterative kucati.
Using the iterative for a single instantaneous action
Skakao je u bazen jednom i izašao.
Skočio je u bazen i izašao.
A single jump is the semelfactive skočiti; skakati means repeated jumping.

Genitive — Partitive & Temporal Uses

Genitiv — dijelni i vremenski

By B1 you already form the genitive; now you sharpen two of its everyday jobs. The partitive genitive marks a part or measured quantity of something: after words for containers, measures and amounts (a glass of water, a kilo of apples), the substance goes in the genitive — čaša vode, kilogram jabuka. The temporal genitive marks a specific date or a point in time without any preposition: 'on the fifth of May' is petog svibnja, and 'one day' (at some past moment) is jednog dana. In both jobs the noun (and any adjective with it) drops into the genitive, even though English would use 'of' or no marking at all. Spotting these two uses keeps you from defaulting to the nominative or the accusative.

Key rule

Put the measured substance into the genitive after quantity/container words, and use the bare genitive (no preposition) to name a date or an indefinite point in time.

Examples

Popio sam čašu vode.
Popio sam čašu voda.
The partitive substance must be genitive singular: vode, not the plural/nominative voda.
Kupila je kilogram jabuka.
Kupila je kilogram jabuke.
After a measure word the counted noun goes into the genitive plural: jabuka.
Rodio se petog svibnja.
Rodio se peti svibanj.
A date is expressed by the bare genitive, so both the ordinal and the month are genitive: petog svibnja.

Common mistakes

Using the nominative for the measured substance
šalica kava
šalica kave
After a container/measure word the substance is partitive genitive, so kava → kave.
Putting the counted noun in the nominative plural after a measure
kilogram jabuke
kilogram jabuka
Measure words govern the genitive plural; the bare-stem form jabuka is the genitive plural.

B1Cases

Dative — Experiencer, Benefactive & Possessive

Dativ — doživljavač, korist, posvojnost

The dative does much more than mark a recipient. In Croatian it also marks the person who experiences a state, the person who benefits, and even a casual possessor. With states like cold, warm, sick or bored, the experiencer goes in the dative: Hladno mi je ('I'm cold', literally 'it is cold to me'). For benefit, the dative shows who something is done for: Kupio joj je dar ('he bought her a present'). And the so-called possessive or ethical dative replaces a possessive when talking about people close to you or about your body: Majka mi je bolesna ('my mother is sick'), Boli me glava but Boli ga glava. Learning to reach for the dative here stops you from forcing English subject-and-possessive patterns onto Croatian.

Key rule

Use the dative for the person who experiences a state (Hladno mi je), who benefits from an action (Kupio joj je dar), or who is the close/inalienable possessor (Majka mi je bolesna).

Examples

Hladno mi je.
Ja sam hladan.
The experiencer of a state is in the dative; 'Ja sam hladan' means 'I am cold/frigid' as a personality, not the sensation.
Kupio joj je prekrasan dar.
Kupio nju je prekrasan dar.
The benefactive person is dative (joj), not accusative (nju).
Majka mi je bolesna.
Moja majka je bolesna meni.
The possessive dative clitic mi naturally expresses 'my mother'; the stressed pronoun meni is wrong here.

Common mistakes

Using a nominative subject for a state
Ja sam hladno.
Hladno mi je.
States like cold/warm/bored are impersonal; the experiencer is dative, with no nominative subject.
Confusing the adjective with the impersonal predicate
Mi smo dosadni.
Dosadno nam je.
Dosadan describes a boring person; the impersonal Dosadno nam je means 'we are bored'.

B1Cases

Instrumental — Means, Manner, Time & Path

Instrumental — sredstvo, način, vrijeme, put

Besides 'with' (company), the instrumental has four prepositionless jobs. Means: the tool or transport you use takes the bare instrumental — putujem vlakom ('I travel by train'), pišem olovkom ('I write with a pencil'). Manner: how something is done — govorim šaptom ('I speak in a whisper'). Time: certain time expressions, especially seasons and parts of the day, go in the instrumental — ljeti, zimi, danju, noću, jutrom, večerom. Path: the route you move along — šetati šumom ('to walk through the forest'), ići cestom ('to go along the road'). In all of these there is NO preposition s/sa — that one is only for company. Recognising the bare instrumental here keeps you from over-using 's' the way English over-uses 'with' or 'by'.

Key rule

Use the bare instrumental (no preposition) for the means/tool, the manner, generic time expressions, and the path travelled; reserve s + instrumental for company.

Examples

Putujem vlakom u Split.
Putujem s vlakom u Split.
Means of transport is the bare instrumental; s would wrongly suggest travelling 'together with the train'.
Pišem zadaću olovkom.
Pišem zadaću s olovkom.
An instrument/tool takes the bare instrumental; no s.
Ljeti idemo na more.
U ljetu idemo na more.
Seasons use the bare instrumental (ljeti), not a preposition + case.

Common mistakes

Adding s to a means of transport
Idem s autobusom.
Idem autobusom.
Means of transport is the bare instrumental; s would imply travelling alongside the bus.
Adding s to an instrument/tool
Reže s nožem.
Reže nožem.
Tools take the bare instrumental; s + instrumental is reserved for company.

B1Cases

Locative vs Accusative — Precision (location vs goal)

Lokativ i akuzativ — preciznost

With the two-case prepositions u, na, pred, za, među, the case you choose answers one question: motion towards a goal or static location? Goal/direction (answering 'where to?', kamo?) takes the accusative: Idem u školu, Stavljam knjigu na stol. Static location (answering 'where?', gdje?) takes the locative (after u, na, o, po) or the instrumental (after pred, nad, pod, među, za): Učim u školi, Knjiga je na stolu, Stojim pred kućom. The same preposition therefore means different things depending on the case. By B1 you should make this choice automatically and also know the idiomatic pairings (na posao/na poslu, u krevet/u krevetu) that learners most often confuse.

Key rule

With two-case prepositions, use the accusative for motion towards a goal (kamo?) and the locative/instrumental for static location (gdje?) — the verb's meaning tells you which.

Examples

Idem u školu.
Idem u školi.
Motion towards a goal takes the accusative: u školu, not the locative.
Učim u školi.
Učim u školu.
A static activity inside a place takes the locative: u školi.
Stavi knjigu na stol.
Stavi knjigu na stolu.
Placing something is directional, so the accusative na stol is required.

Common mistakes

Locative after a motion verb
Idem u trgovini.
Idem u trgovinu.
Motion towards a goal needs the accusative (u trgovinu); the locative is for being there.
Accusative after a stative verb
Radim u uredu... Radim u ured.
Radim u uredu.
Working inside a place is static → locative u uredu.

B1Cases

Genitive-Governing Verbs (bojati se, sjećati se)

Glagoli s genitivom

Some Croatian verbs take their object in the genitive, not the accusative you might expect from English. Many of them are reflexive (used with se) and deal with fear, memory, renunciation or longing: bojati se ('to be afraid of') → Bojim se mraka; sjećati se ('to remember') → Sjećam se djetinjstva; odreći se ('to give up') → Odrekao se cigareta; sramiti se ('to be ashamed of'). A few non-reflexive verbs also govern the genitive (kloniti se, domoći se, dotaknuti se). The thing feared, remembered or given up is genitive even though the English translation looks like a plain direct object. Learn these verbs together with their case so you don't default to the accusative.

Key rule

Verbs like bojati se, sjećati se, odreći se and kloniti se take their object in the genitive, not the accusative.

Examples

Bojim se velikih pasa.
Bojim se velike pse.
Bojati se governs the genitive, so the object is velikih pasa, not the accusative velike pse.
Sjećam se svog djetinjstva.
Sjećam svoje djetinjstvo.
Sjećati se needs both the se and a genitive complement: svog djetinjstva.
Odrekao se svih navika.
Odrekao je sve navike.
Odreći se requires se and a genitive object: svih navika.

Common mistakes

Using the accusative with bojati se
Bojim se pauka u kutu... Bojim pauka.
Bojim se pauka.
Bojati se governs the genitive and requires the reflexive se.
Dropping se from sjećati se
Sjećam to ljeto.
Sjećam se tog ljeta.
The verb is inherently reflexive (se) and takes a genitive complement.

B1Cases

Dative-Governing Verbs (pomoći, vjerovati, smetati)

Glagoli s dativom

Many Croatian verbs take a dative object where English uses a plain direct object. You 'help someone', but in Croatian you pomažeš nekome — pomoći governs the dative. The same goes for vjerovati ('believe/trust') → Vjerujem ti, smetati ('bother') → Smeta mi buka, prijetiti ('threaten'), zahvaljivati / zahvaliti ('thank'), čestitati ('congratulate'), nedostajati ('be missing/miss'), and approach verbs like prići, pristupiti. The person affected is in the dative, not the accusative. Often a dative clitic (mi, ti, mu, joj, nam, vam, im) does the job and slips into second position. Memorise these verbs with their case so you stop saying *pomažem te.

Key rule

Verbs like pomoći, vjerovati, smetati, čestitati and nedostajati take a dative object, not the accusative English leads you to expect.

Examples

Pomažem prijatelju.
Pomažem prijatelja.
Pomoći governs the dative: prijatelju, not the accusative prijatelja.
Vjerujem ti.
Vjerujem te.
Vjerovati takes the dative clitic ti, not the accusative te.
Smeta mi buka.
Smeta me buka.
Smetati governs the dative experiencer (mi), with the noise as subject; me is accusative.

Common mistakes

Accusative object with pomoći
Pomozi me, molim te.
Pomozi mi, molim te.
Pomoći governs the dative; the clitic is mi, not me.
Accusative clitic with vjerovati
Ne vjerujem te.
Ne vjerujem ti.
Vjerovati takes a dative object: ti.

B1Cases

Instrumental-Governing Verbs (baviti se, koristiti se)

Glagoli s instrumentalom

A group of verbs takes its complement in the instrumental — without any preposition. The most common is baviti se ('to do/be engaged in') → Bavim se sportom ('I do sports'). Others include koristiti se ('to use') → Koristim se rječnikom, ponositi se ('to be proud of') → Ponosim se tobom, služiti se ('to use, make use of'), upravljati ('to manage, drive'), rukovati ('to operate'), trgovati ('to trade in'), vladati ('to rule, master'), and oženiti se ('to marry') for a man → Oženio se Anom. The thing you do, use, are proud of or manage goes straight into the instrumental, no s. Many of these are reflexive (with se). Note that plain koristiti can also take a direct accusative object (koristiti rječnik), but with se it is instrumental.

Key rule

Verbs like baviti se, koristiti se, ponositi se, upravljati and vladati take a bare instrumental complement — no preposition s.

Examples

Bavim se plivanjem.
Bavim se plivanje.
Baviti se governs the instrumental: plivanjem, not the nominative/accusative.
Koristim se rječnikom.
Koristim se s rječnikom.
Koristiti se takes a bare instrumental; no s is added.
Ponosim se svojom djecom.
Ponosim se svoju djecu.
Ponositi se governs the instrumental: svojom djecom, not the accusative.

Common mistakes

Adding s to baviti se
Bavim se sa sportom.
Bavim se sportom.
Baviti se takes a bare instrumental; s would imply company.
Accusative complement after ponositi se
Ponosim se svoj uspjeh.
Ponosim se svojim uspjehom.
Ponositi se governs the instrumental: svojim uspjehom.

B1Cases

Case in Apposition & Titles (gradu Zagrebu)

Padež u apoziciji

An apposition is a noun phrase that renames another noun right next to it — 'the city of Zagreb', 'Professor Horvat'. In Croatian, an apposition agrees in CASE with the noun it describes. So 'in the city of Zagreb' is u gradu Zagrebu — both gradu and Zagrebu are in the locative. 'with Professor Horvat' is s profesorom Horvatom — both in the instrumental. The same applies to titles, place names after a generic noun (rijeka Sava, otok Krk, planina Velebit) and people's roles. Learners often decline only the first word and leave the name in the nominative (*u gradu Zagreb), which is wrong: in standard Croatian both parts move into the same case together.

Key rule

An apposition agrees in case with the noun it renames, so both the generic noun and the proper name decline together (u gradu Zagrebu, s profesorom Horvatom).

Examples

Živim u gradu Zagrebu.
Živim u gradu Zagreb.
The apposition agrees in case: both gradu and Zagrebu are locative.
Ljetovali smo na otoku Krku.
Ljetovali smo na otoku Krk.
Krk must also be in the locative: Krku.
Razgovarao sam s profesorom Horvatom.
Razgovarao sam s profesorom Horvat.
The surname Horvat declines in the instrumental: Horvatom.

Common mistakes

Leaving the proper name in the nominative
u gradu Zagreb
u gradu Zagrebu
The apposition agrees in case, so Zagreb → Zagrebu in the locative.
Declining only the name, not the title
gospodin Novaku
gospodinu Novaku
Both the title and the name take the case; gospodin → gospodinu.

B1Orthography

The ije/je Alternation in Inflection & Derivation

Smjenjivanje ije/je u sklonidbi i tvorbi

Standard Croatian is ijekavian, which means the old vowel called jat appears as either 'ije' or 'je'. The tricky part is that the same word root can switch between the two as it changes form. The long 'ije' usually sits in a long syllable, and it shortens to 'je' (or sometimes 'e') when the syllable becomes short in another form. So 'dijete' (child) becomes 'djeteta' in the genitive, 'mlijeko' (milk) gives 'mljekara' (dairy), and 'lijep' (beautiful) gives 'ljepota' (beauty). You cannot just keep 'ije' everywhere; you have to know which form shortens it. This is one of the hardest internal spelling drills for learners because it depends on stress and syllable length, not on meaning.

Key rule

Long jat 'ije' shortens to 'je' (sometimes bare 'e') when the syllable becomes short in inflection or derivation: dijete → djeteta, lijep → ljepota.

Examples

Nemam djeteta kod sebe.
Nemam dijeteta kod sebe.
In the genitive 'djeteta' the syllable shortens, so long 'ije' contracts to short 'je'.
Nemam vremena za to.
Nemam vrijemena za to.
'Vrijeme' shortens to 'vremena' in the genitive; before two consonants the reflex even drops to bare 'e'.
Cijenim njezinu ljepotu.
Cijenim njezinu lijepotu.
The derived noun 'ljepota' uses short 'je', while the base adjective 'lijep' keeps long 'ije'.

Common mistakes

Keeping long 'ije' in shortened forms
Nemam dovoljno vrijemena.
Nemam dovoljno vremena.
When 'vrijeme' inflects to a short syllable the reflex drops to bare 'e': vremena.
Using 'ije' in a derived noun
Divim se njezinoj lijepoti.
Divim se njezinoj ljepoti.
Derivation shortens the syllable, so 'lijep' yields 'ljepota' with short 'je'.

Sibilarization & Palatalization in Declension

Sibilarizacija i palatalizacija u sklonidbi

When a Croatian stem ends in k, g or h, these consonants often change before certain endings. There are two separate processes. Sibilarization turns k, g, h into c, z, s before the ending -i, mostly in the masculine nominative plural and the dative/locative singular of feminine nouns: junak → junaci, ruka → ruci, noga → nozi. Palatalization turns k, g, h into č, ž, š before front vowels in the vocative and in word formation: vuk → vuče, Bog → Bože, duh → duše. Knowing which change applies where lets you build correct plurals, datives and vocatives instead of leaving the velar unchanged.

Key rule

Before -i (masc nom pl, fem dat/loc sg) k/g/h → c/z/s (sibilarization); before front vowels in the vocative and derivation k/g/h → č/ž/š (palatalization).

Examples

Hrabri junaci brane grad.
Hrabri junaki brane grad.
Masculine nominative plural before -i triggers sibilarization: junak → junaci.
Sjedi na ruci, boli ga.
Sjedi na ruki, boli ga.
Feminine dative/locative singular before -i sibilarizes: ruka → ruci.
Hoda po snijegu na nozi koja ga boli.
Hoda po snijegu na nogi koja ga boli.
Locative singular of 'noga' is 'nozi' (g → z before -i).

Common mistakes

No sibilarization in masculine plural
Stari junaki sjede u krčmi.
Stari junaci sjede u krčmi.
Before plural -i the velar k changes to c: junak → junaci.
No sibilarization in feminine dat/loc sg
Nosi prsten na ruki.
Nosi prsten na ruci.
Feminine -a nouns sibilarize before dat/loc -i: ruka → ruci.

Fleeting a (nepostojano a)

Nepostojano a

Many Croatian words have an 'a' that appears in some forms and disappears in others. This is the 'fleeting a' (nepostojano a). It usually shows up in the nominative singular to break up a hard consonant cluster, then drops out as soon as an ending is added: pas (dog) → psa, psu; otac (father) → oca, ocu; the adjective bolestan (sick) → bolesna, bolesno. The opposite also happens: an 'a' gets inserted into the genitive plural of many nouns to ease pronunciation: sestra → sestara, djevojka → djevojaka, pismo → pisama. So you have to know whether a word loses or gains this 'a' as it changes form.

Key rule

An 'a' that breaks up a cluster in the citation form drops when an ending follows (pas → psa, dobar → dobra), and an 'a' is often inserted in the genitive plural (sestra → sestara).

Examples

Bojim se toga psa.
Bojim se toga pasa.
The 'a' of 'pas' is fleeting and drops in the genitive: psa, not 'pasa'.
Dao sam knjigu ocu.
Dao sam knjigu otacu.
'Otac' loses its fleeting 'a' before any ending: oca, ocu, ocem.
Ona je danas bolesna.
Ona je danas bolestana.
The feminine adjective drops the fleeting 'a': bolestan → bolesna.

Common mistakes

Keeping the fleeting a in oblique noun forms
Bojim se velikoga pasa.
Bojim se velikoga psa.
'Pas' drops its 'a' before endings: psa, psu, psom.
Keeping the fleeting a in the feminine adjective
Ona je bolestana.
Ona je bolesna.
Indefinite adjectives lose the fleeting 'a' outside the masc nom sg: bolesna.

B1Orthography

The l/o Alternation

Smjena l/o

In Croatian, a syllable-final 'l' often turns into 'o'. This happens at the end of a word and at the end of a syllable. The clearest case is the masculine past participle (l-participle): the masculine form ends in -o, but as soon as a vowel ending follows, the 'l' comes back: čitao (he read) → čitala (she read), čitali (they read). The same alternation shows up in nouns: posao (job) → posla, poslu; anđeo (angel) → anđela; vol (ox) keeps l but kotao (cauldron) → kotla. So when a word ends in -o that came from an -l, expect the 'l' to reappear in the other forms.

Key rule

Syllable-final 'l' becomes 'o' in the citation form (-ao/-eo) and reappears as 'l' when a vowel ending follows: čitao → čitala, posao → posla.

Examples

On je jučer radio, a ona je radila.
On je jučer radio, a ona je radio.
The feminine l-participle restores the 'l': radio (m) → radila (f).
Tražim novi posao.
Tražim novi poslo.
The nominative is 'posao' with -o from underlying 'l'; the wrong form invents 'poslo'.
Zadovoljan sam svojim poslom.
Zadovoljan sam svojim posaom.
In the instrumental the 'l' returns: posao → poslom, not 'posaom'.

Common mistakes

No l/o alternation in the feminine participle
Ona je cijeli dan radio.
Ona je cijeli dan radila.
The feminine l-participle restores the 'l': radila.
Inventing a wrong noun nominative
Imam dobar poslo.
Imam dobar posao.
The nominative vocalises 'l' to 'o': posao, not 'poslo'.

B1Orthography

Jotation (j-Merger)

Jotacija

Jotation (jotacija) is what happens when a consonant meets a following 'j': the two fuse into a new soft consonant. The most common results are t + j → ć, d + j → đ, s + j → š, z + j → ž, l + j → lj, n + j → nj, and the velars give k + j → č, g + j → ž, h + j → š. You meet jotation in three big places: comparatives of adjectives (čist → čišći, mlad → mlađi), passive participles (nositi → nošen, voditi → vođen), and collective nouns and other derivations (brat → braća, list → lišće). Recognising jotation explains spellings that otherwise look unpredictable.

Key rule

A stem consonant fuses with a following 'j' into a soft consonant (t→ć, d→đ, s→š, z→ž, l→lj, n→nj; labials add 'lj'), as in comparatives, passive participles and collectives: mlad→mlađi, nositi→nošen, list→lišće.

Examples

On je mlađi od mene.
On je mladi od mene.
The comparative of 'mlad' jotates d + j → đ: mlađi (without jotation it looks like the definite adjective 'mladi').
Cijena je već plaćena.
Cijena je već platjena.
platiti → plaćen jotates t + j to ć in the passive participle; the unfused 'tj' is wrong.
Roba je dostavljena na vrijeme.
Roba je dostavljen na vrijeme.
'Dostaviti' → 'dostavljen' jotates the labial v with epenthetic 'lj'; the participle agrees with feminine 'roba'.

Common mistakes

No jotation in the comparative
On je mladji brat.
On je mlađi brat.
d + j fuses to đ in the comparative: mlađi (the spelling 'dj' is wrong here).
Unfused consonant in the passive participle
Knjiga je donesena, a kava nosena.
Knjiga je donesena, a kava nošena.
'Nositi' jotates s → š in the participle: nošen.

B1Vocabulary usage

Word Formation - Basic Suffixes

Tvorba riječi - osnovni sufiksi

Croatian builds a lot of vocabulary by adding suffixes to roots. Learning a few productive suffixes lets you recognise whole word families and guess meanings. The suffix -ač makes a doer or a tool (učitelj is the standard 'teacher', but igrač = player, gledač = viewer). The suffix -ost makes an abstract noun from an adjective (radostan → radost, mlad → mladost, sretan → sreća). The suffix -nje turns a verb into a noun for the action (čitati → čitanje, pisati → pisanje). And -ica often makes a feminine counterpart or a diminutive (učitelj → učiteljica, kuća → kućica). Seeing the suffix tells you the word's type and roughly what it means.

Key rule

Recognise productive suffixes by type: -ač/-telj/-ar (doer), -ost (abstract quality), -nje (action noun), -ica (feminine/diminutive), -ski/-ni (relational adjective).

Examples

Naša učiteljica je vrlo strpljiva.
Naša učiteljka je vrlo strpljiva.
The standard feminine of 'učitelj' is 'učiteljica' with -ica, not the eastern-flavoured 'učiteljka'.
Čitanje mi je najdraža razonoda.
Čitati mi je najdraža razonoda.
As a subject naming the activity, Croatian uses the verbal noun 'čitanje', not the infinitive 'čitati'.
Mladost je prošla prebrzo.
Mladnost je prošla prebrzo.
The abstract noun from 'mlad' is 'mladost' (-ost), not 'mladnost'.

Common mistakes

Wrong feminine-agent suffix
Moja teta je učiteljka.
Moja teta je učiteljica.
Croatian uses -ica for the feminine of -telj/-č agents: učiteljica.
Inventing -nost instead of -ost
Cijenim njegovu mladnost.
Cijenim njegovu mladost.
The abstract suffix is -ost added to the adjective stem: mlad → mladost.

B1Orthography

Comma Rules

Pravila o zarezu

Croatian comma placement follows fairly clear rules. You put a comma before a subordinate clause that comes after the main clause only when needed for clarity, but you always set off a subordinate clause that comes first: 'Kad dođem kući, javit ću ti.' You set off the vocative with commas ('Ivane, dođi ovamo!'), and you set off an apposition ('Zagreb, glavni grad Hrvatske, velik je'). You separate items in a list and parts joined by 'a', 'ali', 'nego', 'no', 'već'. You do NOT put a comma before 'i', 'ili', 'te', 'pa' when they simply join, and you do not split a subject from its verb. The 'inverted order' rule — subordinate clause first — is the one learners forget most.

Key rule

Always put a comma after a fronted subordinate clause, around a vocative and an apposition, and before adversative conjunctions (a, ali, nego, no, već); never before joining i/pa/te/ili or between subject and verb.

Examples

Kad dođem kući, odmah ću te nazvati.
Kad dođem kući odmah ću te nazvati.
A fronted time clause must be set off with a comma (inverted order).
Ivane, dođi ovamo!
Ivane dođi ovamo!
The vocative is always separated by a comma.
Učio je cijelu noć, ali nije položio ispit.
Učio je cijelu noć ali nije položio ispit.
A comma is required before the adversative 'ali'.

Common mistakes

No comma after a fronted clause
Iako je kasno još radim.
Iako je kasno, još radim.
A subordinate clause before the main clause is always followed by a comma.
Missing comma with the vocative
Hvala prijatelju na pomoći.
Hvala, prijatelju, na pomoći.
The vocative must be set off by commas on both sides when mid-sentence.

Ekavian as Contrast - Recognition

Ekavica kao kontrast - prepoznavanje

Standard Croatian is ijekavian: the old jat vowel appears as 'ije' or 'je' (dijete, mlijeko, vrijeme, lijep). In Serbian, the same words usually appear in the ekavian form, with a plain 'e' (dete, mleko, vreme, lep). This is purely a recognition skill for learners of Croatian: you should be able to spot ekavian forms when you meet them in Serbian texts, subtitles or songs, and understand that they correspond to your ijekavian words. But you should NEVER produce ekavian forms in Croatian — in Croatian you always write and say dijete, mlijeko, vrijeme. Ekavian is not a style choice within Croatian; it marks a different standard.

Key rule

Croatian is always ijekavian (dijete, mlijeko, vrijeme); ekavian forms (dete, mleko, vreme) belong to Serbian and are for recognition only — never produce them in Croatian.

Examples

Malo dijete spava u krevetu.
Malo dete spava u krevetu.
Croatian uses the ijekavian 'dijete'; 'dete' is the Serbian ekavian form.
Svako jutro pijem mlijeko.
Svako jutro pijem mleko.
'Mlijeko' is the Croatian standard; 'mleko' is ekavian (Serbian).
Vrijeme je danas lijepo.
Vreme je danas lepo.
Croatian uses ijekavian 'vrijeme' and 'lijepo'; 'vreme' and 'lepo' are the ekavian (Serbian) forms.

Common mistakes

Producing the ekavian noun in Croatian
Imam jedno dete.
Imam jedno dijete.
In Croatian, jat surfaces as 'ije' here: dijete, never the ekavian 'dete'.
Ekavian 'mleko'
Kupi litru mleka.
Kupi litru mlijeka.
Croatian standard is 'mlijeko/mlijeka', the ijekavian form.

B1Clitics

Clitic Cluster — Full Ordering (AUX–DAT–ACC–se–je)

Redoslijed naslonjenica — cjelovito

When several Croatian clitics meet in one sentence, they line up in a single fixed order, all sitting together in second position (right after the first stressed word or phrase). The order never changes: first the auxiliary verb (sam, si, je, smo, ste, su; ću, ćeš…), then the dative pronoun, then the accusative or genitive pronoun, then the reflexive se, and finally je. So you say 'Dao mi ga je' (he gave it to me) — auxiliary issues aside, the dative 'mi' comes before the accusative 'ga'. You cannot reorder these little words for emphasis; if you want to stress something, you move a full stressed form instead. Learning this single chain solves most clitic-placement problems at once.

Key rule

Clitics cluster in second position in the unchangeable order AUX → DAT → ACC/GEN → se → je, with je always last.

Examples

Dao mi ga je.
Dao ga mi je.
Dative 'mi' must precede accusative 'ga'; the order is fixed.
Ivan mi je to rekao.
Ivan je mi to rekao.
The auxiliary 'je' comes before the dative 'mi'; aux opens the cluster.
Knjigu sam ti već vratio.
Knjigu ti sam već vratio.
The auxiliary 'sam' precedes the dative clitic 'ti'.

Common mistakes

Putting accusative before dative
Dao ga mi je.
Dao mi ga je.
The fixed order is dative before accusative: mi (DAT) precedes ga (ACC).
Placing the auxiliary after the pronoun
Ivan mi to je rekao.
Ivan mi je to rekao.
The auxiliary clitic opens the cluster and must precede the pronominal clitics.

B1Clitics

je-Drop with se (nasmijao se, not se je)

Ispadanje je uz se

In the 3rd person singular perfekt (past tense), the auxiliary 'je' normally sits at the very end of the clitic cluster: 'Vidio ga je.' But there is one important exception: when the verb is reflexive and the cluster contains the reflexive 'se', the auxiliary 'je' simply disappears. So you say 'Nasmijao se' (he laughed), not 'nasmijao se je'. The same happens with 'Vratila se' (she came back) and 'Dogodilo se' (it happened). This je-drop occurs ONLY in the 3rd person singular and ONLY with 'se' — every other person keeps its auxiliary (Nasmijao sam se, Nasmijala si se). Remembering this prevents the very common learner mistake of adding an extra 'je'.

Key rule

In the 3rd person singular perfekt with se, the auxiliary je is dropped: nasmijao se, never *nasmijao se je.

Examples

Nasmijao se.
Nasmijao se je.
In 3sg reflexive perfekt the auxiliary 'je' drops; 'se je' is not allowed.
Ana se vratila kasno.
Ana se vratila je kasno.
With 'se' the 3sg 'je' disappears; the verb stands without an auxiliary.
To se dogodilo prošle godine.
To se dogodilo je prošle godine.
Impersonal 3sg reflexive also drops 'je'.

Common mistakes

Adding je after se in 3sg perfekt
Vratio se je sinoć.
Vratio se sinoć.
The 3sg auxiliary je is obligatorily deleted when se is present.
Dropping the auxiliary in non-3sg persons (intending 1sg feminine 'I laughed')
Nasmijala se.
Nasmijala sam se.
The je-drop applies only to 3sg; 1sg keeps the auxiliary sam, so 'I laughed' (fem.) is 'nasmijala sam se'.

B1Clitics

The Interrogative li — Separate from the Cluster

Upitna čestica li — odvojeno od niza

The little question word 'li' turns a statement into a yes/no question, but it behaves differently from the pronoun clitics. 'Li' is NOT a member of the AUX–DAT–ACC–se–je chain. Instead it attaches directly after the word that is fronted or focused — usually the verb or an auxiliary: 'Dolaziš li sutra?' (Are you coming tomorrow?), 'Vidiš li ovo?' (Do you see this?). With biti you get the fixed pattern 'Je li…?' (Je li on doma?). 'Li' always comes immediately after that first stressed word and pushes any pronoun clitics after itself: 'Vidiš li ga?' Don't try to slot 'li' into the pronoun chain — it lives on its own, glued to the focused element.

Key rule

li is a question particle that clings to the fronted/focused word and precedes the pronoun clitics — it is never a slot inside the AUX–DAT–ACC–se–je chain.

Examples

Dolaziš li sutra?
Li dolaziš sutra?
li attaches AFTER the focused verb and can never start the clause.
Vidiš li ga?
Vidiš ga li?
li comes immediately after the host verb, before the pronoun clitic ga.
Jesi li mu to rekao?
Si li mu to rekao?
Questions with biti use the full jesi, not the clitic si; li follows jesi.

Common mistakes

Starting a question with li
Li ideš s nama?
Ideš li s nama?
li is enclitic and cannot open a clause; it must follow the focused word.
Using the clitic auxiliary with li
Si li umoran?
Jesi li umoran?
Yes/no questions with biti require the full form jesi, then li.

B1Pronouns

koji — Full Declension & Relative Use

Sklonidba i relativna uporaba zamjenice koji

'Koji' (which, who, that) is the main word for joining a relative clause to a noun. It always agrees in GENDER and NUMBER with the noun it refers to (its antecedent), but its CASE is decided by the job it does inside the relative clause — not by the case of the antecedent. So in 'čovjek kojeg vidim' (the man whom I see), 'koji' is masculine singular (matching čovjek) but accusative 'kojeg' because it is the object of 'vidim'. In 'kuća u kojoj živim' (the house in which I live), it is feminine singular but locative after 'u'. Decline koji like a definite adjective: koji, kojeg(a), kojem(u), kojim, etc. Get the gender/number from the noun, the case from the verb or preposition inside the clause.

Key rule

koji agrees in gender and number with its antecedent but takes its case from its role inside the relative clause.

Examples

Čovjek kojeg vidim je moj susjed.
Čovjek koji vidim je moj susjed.
koji is the object of 'vidim', so it must be accusative (animate kojeg), not nominative.
Kuća u kojoj živim je stara.
Kuća u koju živim je stara.
After 'u' meaning location, koji is locative (kojoj), not accusative.
Prijateljica koju poznajem dolazi sutra.
Prijateljica koja poznajem dolazi sutra.
koji is the object of 'poznajem', so it is accusative koju, not nominative koja.

Common mistakes

Taking the case from the antecedent instead of the clause
Čovjeka kojeg vidim. (as subject of main clause)
Čovjek kojeg vidim.
The main-clause noun keeps its own case; koji's case comes from its role in the relative clause.
Assuming koji must change for an inanimate object
Čovjek koji gledam.
Čovjek kojeg gledam.
Inanimate masculine accusative equals the nominative form (film koji gledam), but an animate masculine object takes the genitive-like accusative kojeg: čovjek kojeg gledam.

B1Pronouns

Relative tko / što / čiji

Odnosne zamjenice tko, što, čiji

Besides 'koji', Croatian has three other relativisers. 'Tko' (who) is used for an unspecified person, usually after the pointing word 'onaj': 'Onaj tko radi, uspije' (Whoever works, succeeds). 'Što' (what / that) is used after 'ono' for an unspecified thing — 'Ono što vidim…' (What I see…) — and also to refer back to a WHOLE preceding clause: 'Zakasnio je, što me naljutilo' (He was late, which annoyed me). 'Čiji' (whose) introduces a possessive relative clause and agrees with the thing possessed: 'čovjek čija kći studira' (the man whose daughter studies). 'Tko' and 'što' decline like the question words (tko–koga–komu…; što–čega–čemu…); 'čiji' declines like a possessive adjective.

Key rule

Use tko for an indefinite person (with onaj), što for an indefinite thing or a whole-clause antecedent (with ono), and čiji ('whose') agreeing with the possessed noun.

Examples

Onaj tko mnogo radi, mnogo i postigne.
Onaj koji tko mnogo radi, mnogo i postigne.
After 'onaj' for a generic person, use 'tko' alone, not 'koji tko'.
Ono što tražiš nalazi se ovdje.
Ono koji tražiš nalazi se ovdje.
For an indefinite thing after 'ono', use 'što', not 'koji'.
Zakasnio je, što me jako naljutilo.
Zakasnio je, koji me jako naljutilo.
Referring back to the whole clause requires 'što', never 'koji'.

Common mistakes

Using koji instead of što for a clause antecedent
Kasnio je, koji me naljutilo.
Kasnio je, što me naljutilo.
When the antecedent is a whole clause, only 'što' is possible.
Using koji after onaj/ono for a generic referent
Onaj koji laže...
Onaj tko laže...
A generic person introduced by 'onaj' takes 'tko', not 'koji'.

Indefinite Pronouns — Full Set (netko, gdjekoji, bilo tko, svatko)

Neodređene zamjenice — cjelovito

Croatian builds indefinite pronouns from the question words tko/što/koji/čiji by adding small elements. The 'ne-' series means 'some-': netko (someone), nešto (something), neki (some), nečiji (someone's). The 'sva-' series means 'every-': svatko (everyone), svašta (all sorts of things), svaki (each). The 'bilo-' series (and the suffix -god) means 'any-': bilo tko (anyone at all), bilo što (anything), tkogod, štogod. There is also 'gdjekoji' / 'pokoji' meaning 'the odd one, a few here and there'. These pronouns still decline like the base word: netko → nekoga, nekomu; nešto → nečega, nečemu. Choosing the right series — some / every / any — is the key, and each keeps the case forms of its root pronoun.

Key rule

Build indefinites on tko/što/koji by series: ne- = 'some-', sva- = 'every-', bilo-/-god = 'any-'; each keeps the case forms of its base word.

Examples

Netko te traži na vratima.
Neko te traži na vratima.
Standard Croatian uses 'netko'; 'neko' is colloquial/eastern.
Trebam nešto pojesti.
Trebam nešta pojesti.
The form is 'nešto'; 'nešta' is non-standard colloquial.
Svatko zna odgovor na to pitanje.
Svako zna odgovor na to pitanje.
For 'everyone' (a person) standard Croatian uses 'svatko', not 'svako'.

Common mistakes

Using the eastern short forms neko/svako
Neko je zvao.
Netko je zvao.
Standard Croatian person-indefinites are netko/svatko, not neko/svako.
Failing to decline bilo tko / bilo što
Daj to bilo tko.
Daj to bilo komu.
The base pronoun still declines; 'bilo' stays fixed while komu carries the dative.

B1Pronouns

Negative Pronouns — Full Set + Prepositions (ni od koga)

Niječne zamjenice + prijedlozi (ni od koga)

The negative pronouns are built with 'ni-': nitko (nobody), ništa (nothing), nikoji/nijedan (no, not any), ničiji (nobody's), nikakav (no kind of). Two rules are essential. First, OBLIGATORY double negation: a ni-word always needs 'ne' on the verb — 'Nitko ne zna' (Nobody knows), 'Ništa ne vidim' (I see nothing). Leaving out 'ne' is wrong. Second, when a preposition is involved, it SPLITS the ni-word and goes in the middle: not 'od nikoga' but 'ni od koga'; not 's nikim' but 'ni s kim'; not 'o ničemu' but 'ni o čemu'. The ni-part stays at the front, the preposition sits between ni and the case form. These two habits — keep the 'ne' on the verb and split the ni- around the preposition — are what learners most often miss.

Key rule

Negative ni-pronouns require 'ne' on the verb (double negation) and split around any preposition: ni od koga, ni s kim, ni o čemu.

Examples

Nitko ne zna istinu.
Nitko zna istinu.
A ni-word obligatorily needs 'ne' on the verb; double negation is required in Croatian.
Ništa ne razumijem.
Ništa razumijem.
'ne' on the verb is mandatory with ništa.
Ne ovisim ni o kome.
Ne ovisim o nikome.
The preposition splits the ni-word: 'ni o kome', not 'o nikome'.

Common mistakes

Omitting ne on the verb (no double negation)
Nitko dolazi.
Nitko ne dolazi.
Croatian has obligatory negative concord; the ni-pronoun and the verbal 'ne' must both appear.
Not splitting the ni-word around a preposition
Ne družim se s nikim.
Ne družim se ni s kim.
A preposition is inserted between ni- and the base: ni s kim, ni o čemu, ni od koga.

Possessive Dative (Majka mi je…) vs Possessive Pronoun

Posvojni dativ vs posvojna zamjenica

Croatian has two ways to show that something belongs to someone. The full possessive pronoun (moj, tvoj, njegov…) is the neutral choice: 'Moja majka je bolesna' (My mother is ill). But very often, especially with family members, body parts and close personal things, Croatian uses a short DATIVE clitic pronoun instead: 'Majka mi je bolesna' (literally 'Mother is ill to-me'). The clitic mi/ti/mu/joj sits in second position and points to the possessor. This possessive (or 'sympathetic') dative is extremely common for inalienable possession — 'Boli me glava' (My head hurts), 'Drago mi je' (I'm glad). It sounds warmer and more idiomatic than a heavy possessive pronoun. Learn to recognise when natives prefer the dative clitic over moj/tvoj.

Key rule

For close (inalienable) possession — family, body parts, personal states — Croatian prefers a second-position dative clitic (Majka mi je…) over a heavy possessive pronoun (Moja majka je…).

Examples

Majka mi je bolesna.
Majka mi je bolesna mene.
The dative clitic 'mi' alone signals the possessor; adding a stressed pronoun is redundant.
Sin joj studira medicinu.
Njezin sin joj studira medicinu.
Either the possessive pronoun OR the dative clitic — using both together is redundant.
Boli me glava.
Boli moja glava.
Body-part pain uses the experiencer pronoun (me), not a possessive 'moja glava'.

Common mistakes

Combining a possessive pronoun and a possessive dative
Moja mi je majka bolesna.
Majka mi je bolesna.
Use either the possessive pronoun or the dative clitic, not both for the same possessor.
Possessive pronoun for body-part pain
Boli moja glava.
Boli me glava.
Croatian expresses pain with the experiencer pronoun (me), not a possessive adjective.

Relative Clauses with koji

Odnosne rečenice s koji

Relative clauses let you add information about a noun without starting a new sentence. The main tool in Croatian is the relative pronoun koji ('who/which/that'). The trick that confuses learners is this: koji takes its GENDER and NUMBER from the noun it refers back to, but it takes its CASE from the job it does inside the relative clause itself. So if you talk about a man and koji is the subject of its own clause, it stays nominative (čovjek koji radi). If that same man is the object, koji becomes accusative (čovjek kojeg vidim). A comma normally separates the relative clause from the main clause.

Key rule

koji agrees in gender and number with its antecedent but takes its case from its role inside the relative clause.

Examples

Ovo je čovjek koji živi pokraj nas.
Ovo je čovjek kojeg živi pokraj nas.
koji is the subject of 'živi', so it must be nominative koji, not accusative kojeg.
Knjiga koju čitam je odlična.
Knjiga koja čitam je odlična.
Inside the clause koji is the direct object of čitam, so feminine accusative koju, not nominative koja.
Grad u kojem sam odrastao je malen.
Grad koji sam odrastao u je malen.
The preposition u must stand before koji and governs the locative kojem; Croatian does not strand prepositions at the end.

Common mistakes

Using nominative for an object role
Pjesma koja slušam je nova.
Pjesma koju slušam je nova.
Inside the clause koji is the direct object of slušam, so feminine accusative koju is required, not nominative koja.
Animacy ignored in masculine accusative
Dječak koji sam vidio plače.
Dječak kojeg sam vidio plače.
Animate masculine accusative takes the genitive-like form kojeg, not the bare koji.

B1Syntax

Relative što for a Whole-Clause Antecedent

Odnosno što za cijelu rečenicu

Sometimes the thing you want to comment on is not a single noun but a whole idea — the entire previous statement. English uses 'which' for this: 'He was late, which annoyed me.' Croatian does NOT use koji here, because there is no noun to agree with. Instead it uses što. So: Zakasnio je, što me naljutilo ('He was late, which annoyed me'). The rule is simple to remember: koji points back to a noun, but što points back to a whole clause or general idea. A comma always comes before this što.

Key rule

Use što (not koji) when the relative clause refers back to a whole clause or general idea rather than a single noun.

Examples

Zakasnio je na sastanak, što me jako naljutilo.
Zakasnio je na sastanak, koji me jako naljutilo.
The relative refers to the whole event of being late, not a noun, so što, not koji.
Dobila je posao, čemu se jako veseli.
Dobila je posao, koji se jako veseli.
Radovati/veseliti se takes the dative, so sentential što appears in the dative čemu.
Ono što me najviše muči je nesigurnost.
Koje me najviše muči je nesigurnost.
Headless relative 'the thing that' uses ono što, not koji.

Common mistakes

Using koji for a whole-clause antecedent
Pao je na ispitu, koji ga je rastužilo.
Pao je na ispitu, što ga je rastužilo.
There is no noun to agree with; the antecedent is the whole event, so što is required.
Wrong participle gender after sentential što
Otišla je, što me iznenadila.
Otišla je, što me iznenadilo.
Sentential što is neuter, so the past participle is neuter iznenadilo.

B1Syntax

Indirect Questions (Ne znam gdje je / dolazi li)

Zavisno-upitne rečenice

An indirect question is a question buried inside another sentence: 'I don't know where he is.' Croatian handles two types. For wh-questions, keep the question word (gdje, kada, tko, zašto…) and attach the clause: Ne znam gdje je. For yes/no questions, there is no Croatian word for 'whether/if' as a conjunction — instead you use the particle li placed right after the verb: Ne znam dolazi li ('I don't know whether he is coming'). Unlike a direct question, the indirect clause does NOT keep question intonation and does not get a question mark. Word order stays normal statement order in wh-questions.

Key rule

Embed wh-questions with the question word kept in place; embed yes/no questions with li after the verb — Croatian has no 'whether' conjunction.

Examples

Ne znam gdje stanuje.
Ne znam gdje stanuje li.
li is only for yes/no questions; a wh-question already has the question word gdje, so no li.
Pitam se dolazi li sutra.
Pitam se ako dolazi sutra.
There is no 'whether' conjunction; yes/no embedding uses verb + li, not ako.
Reci mi je li sve u redu.
Reci mi da li je sve u redu?
Standard Croatian uses je li (verb + li); also the sentence is a statement, so no question mark.

Common mistakes

Using ako for 'whether'
Ne znam ako dolazi.
Ne znam dolazi li.
Ako means 'if' in conditionals; embedded yes/no questions use verb + li, not ako.
Adding li to a wh-question
Pitam se gdje je li.
Pitam se gdje je.
li only embeds yes/no questions; wh-questions already carry their question word.

B1Syntax

Reported Speech (Rekao je da…)

Neupravni govor

Reported (indirect) speech is when you tell what someone said without quoting them word for word: 'He said that he was tired' → Rekao je da je umoran. Croatian uses da to introduce the reported statement. The good news for English speakers: Croatian does NOT shift the tense backwards. If the original words were 'I am tired' (present), the report keeps the present: Rekao je da je umoran — literally 'He said that he IS tired.' What does change are the pronouns and possessives, exactly as in English (I → he, my → his). Questions are reported with question words or li (see indirect questions), and commands with da + present or neka.

Key rule

Report statements with da and KEEP the original tense — Croatian shifts pronouns, not tenses.

Examples

Rekao je da je umoran.
Rekao je da je bio umoran.
His original words were present ('Umoran sam'), so the report keeps the present je umoran; no backshift.
Rekla je da dolazi sutra.
Rekla je da je dolazila sutra.
Original present dolazim stays present dolazi; Croatian has no sequence-of-tenses shift.
Tvrdi da će sve biti gotovo.
Tvrdi da bi sve biti gotovo.
A future statement stays future će biti; bi (conditional) is wrong here.

Common mistakes

Backshifting the tense like English
Rekao je da je bio sretan.
Rekao je da je sretan.
When he is still happy, Croatian keeps the original present; there is no sequence of tenses.
Using da for reported questions
Pitao je da gdje smo bili.
Pitao je gdje smo bili.
Reported wh-questions keep the question word without da.

B1Syntax

Conditional Sentences — Real vs Unreal

Pogodbene rečenice — stvarne i nestvarne

Croatian has two clearly different 'if' patterns. REAL conditions (things that may well happen) use ako + present or future: Ako padne kiša, ostat ćemo doma ('If it rains, we'll stay home'). UNREAL conditions (hypothetical or contrary to fact) use da + present in the if-clause and the conditional (bih, bi, bismo…) in the main clause: Da imam vremena, došao bih ('If I had time, I would come'). The key choice: ako for realistic conditions, da for imagined ones. Mixing them up — using ako with the conditional, or da for a realistic future — is the classic mistake.

Key rule

Real conditions use ako + present/future; unreal conditions use da + present in the if-clause with the conditional (bih/bi…) in the main clause.

Examples

Ako padne kiša, ostat ćemo kod kuće.
Ako bi pala kiša, ostat ćemo kod kuće.
A realistic future condition uses ako + present (padne), not ako + conditional.
Da imam vremena, došao bih.
Ako imam vremena, došao bih.
A hypothetical condition uses da + present with the conditional, not ako.
Ako budeš imao vremena, nazovi me.
Ako ćeš imati vremena, nazovi me.
A future condition after ako standardly uses futur II (budeš imao), not futur I.

Common mistakes

Using ako with the conditional
Ako bih imao vremena, došao bih.
Da imam vremena, došao bih.
Standard Croatian forms the unreal if-clause with da + present, not ako + bih.
Using da for a realistic future condition
Da padne kiša, ostat ćemo doma.
Ako padne kiša, ostat ćemo doma.
Realistic, likely conditions use ako, not the hypothetical da.

B1Syntax

Purpose Clauses with da / kako bi

Namjerne rečenice (da, kako bi)

A purpose clause answers 'why / for what purpose?' — 'I study (in order) to pass the exam.' Croatian has two main patterns. (1) da + present: Učim da položim ispit. (2) kako bi + the conditional (or da bih): Učim kako bih položio ispit. Both mean 'in order to'. When the subject of both clauses is the same, Croatian often just uses da + present, which is the most natural everyday choice. kako bi is slightly more formal/explicit. Watch out: Croatian does NOT use a bare infinitive 'to pass' here in the standard way English does — it uses a full clause with da or kako bi.

Key rule

Express purpose with da + present (neutral) or kako bi + conditional (more formal) — not with a bare infinitive.

Examples

Učim hrvatski da bolje razumijem ljude.
Učim hrvatski razumjeti ljude bolje.
Purpose needs a da-clause (da razumijem), not a bare infinitive tacked on.
Govori sporije kako bih te razumio.
Govori sporije kako bih te razumjeti.
kako bi takes the past participle (razumio), not the infinitive.
Dao sam mu ključ da otključa vrata.
Dao sam mu ključ da otključati vrata.
After da the verb is the present (otključa), not the infinitive.

Common mistakes

Using a bare infinitive of purpose
Idem u trgovinu kupiti kruh za jesti.
Idem u trgovinu da kupim kruh.
Standard purpose is da + present; za + infinitive is non-standard.
Infinitive after da
Učim da položiti ispit.
Učim da položim ispit.
After da the verb is in the present, not the infinitive.

B1Syntax

Concessive Clauses (iako, premda, makar)

Dopusne rečenice (iako, premda, makar)

A concessive clause expresses 'although / even though' — it sets up something you'd expect to block the main action, but the main action happens anyway: 'Although it was raining, we went out.' Croatian uses iako, premda (a bit more formal), and makar/mada. Example: Iako je padala kiša, izašli smo. The main clause sometimes has the 'echo' word ipak ('still, nevertheless'): Iako je umoran, ipak radi. Note that, unlike English, Croatian normally does NOT put a second conjunction in the main clause — there is no 'although… but…' pairing; the comma and ipak do that job.

Key rule

Use iako / premda / makar for 'although'; mark the contrast with ipak in the main clause — never a second conjunction like ali.

Examples

Iako je padala kiša, izašli smo van.
Iako je padala kiša, ali izašli smo van.
Croatian uses only one subordinator; the main clause must not add ali.
Premda je bio umoran, nastavio je raditi.
Premda je bio umoran, no nastavio je raditi.
No second connector (no) is added in the main clause of a concessive sentence.
Iako mnogo zarađuje, nije sretan.
Iako on mnogo zarađuje, nije sretan ipak ali.
One concession marker is enough; stacking ipak and ali is wrong.

Common mistakes

Doubling with 'but' (English pattern)
Iako je teško, ali pokušat ću.
Iako je teško, pokušat ću.
Croatian allows only one subordinator; do not add ali in the main clause.
Doubling with no/ipak ali
Premda pada kiša, no ipak idemo.
Premda pada kiša, ipak idemo.
Use one contrast marker (ipak); no/ali stacked on top is incorrect.

B1Connectors

Temporal Connectors — Advanced (čim, prije nego, nakon što, otkad)

Vremenski veznici — prošireno

Beyond the basic kad ('when'), Croatian has precise time connectors. čim = 'as soon as' (Čim stignem, javit ću ti). prije nego (što) = 'before' (Operi ruke prije nego što jedeš). nakon što / pošto = 'after' (Nakon što sam završio, otišao sam). otkad / otkako = 'since' (Otkad živim ovdje, sretniji sam). dok = 'while/until'. The big thing to get right is aspect: with 'as soon as' and 'after', use the perfective (one completed event); with 'while', use the imperfective (ongoing background). A comma separates the time clause from the main clause.

Key rule

Match aspect to the connector: čim / nakon što / prije nego što take the perfective; dok ('while') takes the imperfective; 'until' is dok ne + perfective.

Examples

Čim stignem kući, javit ću ti se.
Čim stižem kući, javit ću ti se.
'As soon as' marks a single completed arrival → perfective stignem, not imperfective stižem.
Operi ruke prije nego što jedeš.
Operi ruke prije jedeš.
Standard Croatian uses prije nego (što) before a clause; bare prije + clause is wrong.
Nakon što smo večerali, prošetali smo.
Nakon što večeramo, prošetali smo.
A completed prior event → perfective past smo večerali, matching the past main clause.

Common mistakes

Imperfective after čim
Čim dolazim, zovem te.
Čim dođem, zvat ću te.
'As soon as' marks one completed event → perfective dođem.
Bare prije + clause
Nazovi me prije ideš.
Nazovi me prije nego što odeš.
'Before' a clause requires prije nego (što), not bare prije.

Cause & Consequence (budući da, stoga, zbog toga)

Uzrok i posljedica (budući da, stoga)

To link a reason to a result in good Croatian you have several tools. For the CAUSE: jer ('because', most common, follows the main clause) and budući da / pošto ('since/as', often FRONTED at the start). For the CONSEQUENCE: zato, stoga, zbog toga, dakle ('therefore/so'). Example: Budući da je padala kiša, ostali smo doma ('Since it was raining, we stayed home'); or Padala je kiša, stoga smo ostali doma. A key style rule: jer normally cannot start a sentence, but budući da typically does. zbog + genitive expresses cause with a noun (zbog kiše = 'because of the rain'), while jer/budući da introduce a whole clause.

Key rule

Use jer (post-posed) or budući da (fronted) for the cause, and stoga / zato / zbog toga for the consequence; use zbog + genitive for cause expressed by a noun.

Examples

Ostao sam kod kuće jer je padala kiša.
Jer je padala kiša, ostao sam kod kuće.
jer does not begin a sentence in standard style; front the cause with budući da instead.
Budući da je padala kiša, ostali smo kod kuće.
Budući je padala kiša, ostali smo kod kuće.
The conjunction is budući DA; the da cannot be dropped.
Padala je kiša, stoga smo ostali doma.
Padala je kiša, stoga što smo ostali doma.
stoga alone introduces the consequence; stoga što would mean 'because' and is wrong here.

Common mistakes

Starting a sentence with jer
Jer je kasno, idem spavati.
Budući da je kasno, idem spavati.
jer does not begin a sentence in standard Croatian; front the cause with budući da.
Dropping da from budući da
Budući je hladno, obuci jaknu.
Budući da je hladno, obuci jaknu.
The conjunction is the fixed phrase budući da; da is obligatory.

B1Connectors

Paired Connectors (i… i; ili… ili; ni… ni; ne samo… nego i)

Višestruki veznici (i…i, ili…ili, ni…ni)

Croatian has 'paired' (correlative) connectors that come in two parts, one before each item. i… i = 'both… and' (i Ana i Marko = 'both Ana and Marko'). ili… ili = 'either… or'. ni… ni = 'neither… nor'. ne samo… nego i = 'not only… but also'. The tricky one is ni… ni: because Croatian uses double negation, the verb must ALSO be negated: Ne volim ni kavu ni čaj ('I like neither coffee nor tea' — literally 'I don't like nor coffee nor tea'). With i… i joining two subjects, the verb is usually plural. Each part of the pair stands directly before the element it introduces.

Key rule

Place each correlative marker before its item; with ni… ni the verb MUST also be negated (double negation), and after a negation use nego/već, not ali.

Examples

I Ana i Marko vole more.
Ana i Marko i vole more.
In i… i ('both… and') each i stands before its conjunct: I Ana i Marko, not after them.
Ne pijem ni kavu ni čaj.
Pijem ni kavu ni čaj.
ni… ni requires the verb to be negated: ne pijem; Croatian uses double negation.
Ili ćeš doći ili ćeš nazvati.
Ili doći ili nazvati ćeš.
Each ili introduces a full parallel clause with its own verb; the clitic ćeš stays in second position in each.

Common mistakes

No verb negation with ni… ni
Volim ni kavu ni čaj.
Ne volim ni kavu ni čaj.
Croatian uses concord negation: the verb must be negated alongside ni… ni.
Using ali after a negation instead of nego/već
Ne samo da uči nego ali i radi.
Ne samo da uči nego i radi.
After a negative, the adversative is nego/već, not ali.

B1Connectors

Additive & Adversative (osim toga, međutim, naprotiv, štoviše)

Suprotni i dodatni veznici (međutim, naprotiv)

These are written-register linking words that join sentences smoothly. ADDITIVE (adding more): osim toga ('besides/moreover'), štoviše ('what's more, indeed'), također ('also'), uz to ('on top of that'). ADVERSATIVE (contrast): međutim ('however'), naprotiv ('on the contrary'), ipak ('nevertheless'), s druge strane ('on the other hand'). These usually stand at the START of a new sentence (or after a semicolon), set off by a comma: Bilo je hladno. Međutim, izašli smo. Unlike ali ('but'), which joins clauses inside one sentence, međutim typically begins a fresh sentence. naprotiv is strong: it cancels and reverses the previous statement ('on the contrary'), not just contrasts.

Key rule

Use osim toga / štoviše to add and međutim / naprotiv to contrast at the start of a new sentence, set off by a comma — they replace, not accompany, ali.

Examples

Stan je malen. Međutim, vrlo je svijetao.
Stan je malen, međutim vrlo je svijetao i to.
međutim opens a new sentence and is set off by a comma; the trailing i to is unnecessary.
Hrana je bila odlična. Osim toga, cijena je bila niska.
Hrana je bila odlična, osim toga cijena je bila niska.
osim toga normally begins a new sentence with a following comma, not a mid-sentence comma splice.
Nije bilo dosadno; naprotiv, svi smo uživali.
Nije bilo dosadno; naprotiv, bilo je malo dosadno.
naprotiv reverses the previous claim, so what follows must be the opposite, not a partial repeat.

Common mistakes

Stacking ali with međutim
Skupo je, ali međutim isplati se.
Skupo je. Međutim, isplati se.
Use ali (in-sentence) OR međutim (new sentence), not both; međutim then needs a comma.
Comma splice with međutim
Bilo je kasno, međutim ostali smo.
Bilo je kasno. Međutim, ostali smo.
međutim is a sentence connector; join with a period/semicolon and set it off with a comma.

B1Syntax

Word Order for Emphasis — Introduction

Red riječi i naglašavanje (uvod)

Croatian word order is flexible because the case endings show who does what, not the position. The neutral order is Subject–Verb–Object (Marko čita knjigu), but you can move words around to EMPHASISE them. The general rule: known/old information comes first, NEW or important information comes later — or you front a word to put a spotlight on it. Knjigu čita Marko ('It's Marko who reads the book' / 'As for the book, Marko reads it'). The one thing that does NOT move freely is the clitics (je, su, sam, me, ga, mu, se, ću…): they must stay in SECOND position in the clause, no matter how you rearrange the rest.

Key rule

Reorder major constituents for emphasis (front a word to spotlight it; new information goes later), but always keep clitics in second position.

Examples

Marko je kupio auto.
Je Marko kupio auto.
Neutral SVO order; the clitic je cannot begin the clause — it sits in second position.
Auto je kupio Marko.
Auto kupio je Marko.
Fronting the object is fine, but the clitic je must stay in second position, right after auto.
Tebe sam zvao, a ne njega.
Sam zvao tebe, a ne njega.
Contrastive fronting of tebe is correct; the clitic sam stays second, after tebe, never first.

Common mistakes

Clitic in first position
Je kupio Marko auto.
Marko je kupio auto.
Enclitics cannot start a clause; they must occupy the second position.
Clitic pushed out of second position by fronting
Auto kupio je Marko.
Auto je kupio Marko.
When you front the object, the clitic je must still come immediately after the first element.

B1Verb tenses

Futur II — Formation (budem + l-participle)

Futur drugi — tvorba (budem + glagolski pridjev radni)

Futur II (the 'second future') is the tense Croatian uses inside subordinate clauses to talk about an action that will happen before, or at the same time as, the main future action. You build it with the present of 'budem' (budem, budeš, bude, budemo, budete, budu) plus the l-participle, which agrees with the subject in gender and number — exactly like the perfekt participle. You almost never start a sentence with it: it lives after words like 'kad', 'ako', 'čim', 'dok'. The main clause then carries futur I. So you say 'Kad budem došao, javit ću ti' — 'When I arrive, I'll let you know.' Aspect matters: a perfective participle means a completed action, an imperfective one an ongoing background.

Key rule

Use the present of 'budem' plus the l-participle (agreeing in gender/number) for future actions inside subordinate clauses; the main clause stays in futur I.

Examples

Kad budem došao, javit ću ti.
Kad ću doći, javit ću ti.
Standard Croatian forbids futur I after 'kad' for the future; the subordinate clause needs futur II (budem došao).
Ako budeš imala vremena, pomozi mi.
Ako budeš imao vremena, pomozi mi.
The l-participle must agree with a feminine subject: imala, not imao.
Čim budemo stigli, nazvat ćemo te.
Čim budemo stignuli, nazvat ćemo te.
The participle of 'stići' is 'stigli', not the regularized '*stignuli'.

Common mistakes

Using futur I in a temporal/conditional clause
Kad ću doći, javit ću ti.
Kad budem došao, javit ću ti.
After 'kad', 'ako', 'čim', 'dok' the future must be futur II; futur I belongs only in the main clause.
Infinitive instead of l-participle after budem
Ako budeš imati vremena.
Ako budeš imala vremena.
Futur II is 'budem' + l-participle, which agrees with the subject; the infinitive is never used here.

B1Verb tenses

Pluskvamperfekt — Past-before-Past

Pluskvamperfekt

The pluskvamperfekt (pluperfect) is Croatian's 'past-before-past': it marks an action already completed before another past event. You build it with the perfekt of 'biti' — that is, 'bio sam / bila sam / bilo je' — plus the l-participle of the main verb, both agreeing with the subject in gender and number. So 'Bio sam već otišao kad je nazvala' means 'I had already left when she called.' It is less common than in English; in casual speech Croatian often just uses the ordinary perfekt with a word like 'već' (already) or 'prije' (before). But you'll meet it in narrative, and it's the precise way to order two past events.

Key rule

Form the pluperfect with the perfekt of biti (bio/bila + sam/si/je…) plus the main verb's l-participle, both agreeing with the subject, for an action completed before another past event.

Examples

Bio sam već otišao kad je nazvala.
Bio sam već otišla kad je nazvala.
Both participles must agree with a masculine speaker: bio… otišao, not otišla.
Kad smo stigli, vlak je već bio otišao.
Kad smo stigli, vlak je već otišao.
The pluperfect needs 'bio' + participle to mark the train left before our arrival; plain perfekt loses the ordering.
Ana je bila zaspala prije ponoći.
Ana je bio zaspala prije ponoći.
The auxiliary participle agrees in gender: feminine 'bila', not 'bio'.

Common mistakes

Auxiliary participle not agreeing with subject
Ona je bio otišla.
Ona je bila otišla.
'bio/bila/bilo' agrees with the subject; a feminine subject needs 'bila'.
Using plain perfekt where ordering matters
Kad sam stigao, vlak je otišao.
Kad sam stigao, vlak je već bio otišao.
To show the train left before arrival, the pluperfect (bio + participle) is needed.

B1Verb tenses

Aorist — Formation & Use

Aorist — tvorba i uporaba

The aorist is a simple (one-word) past tense built mostly from perfective verbs. It tells of a single completed action and gives narration a vivid, immediate feel — 'reče' (he said), 'dođe' (he came), 'rekoh' (I said). You form it from the infinitive stem with endings -h, -∅/-e, -∅/-e, -smo, -ste, -še. In modern everyday speech the aorist is largely replaced by the perfekt, but it stays alive in storytelling, exclamations ('Odoh ja!' — I'm off!), and set phrases. As a learner you mostly need to recognise it, and to produce a handful of high-frequency forms like 'reče', 'dođe', 'bî' from biti.

Key rule

Form the aorist from the (usually perfective) infinitive stem plus -h, -e/-∅, -e/-∅, -smo, -ste, -še to express a single completed past action with vivid, narrative force.

Examples

Reče mi istinu i ode.
Reko mi istinu i ode.
The 3sg aorist of 'reći' is 'reče' (palatalized), not '*reko'.
Dođosmo kući kasno navečer.
Dođesmo kući kasno navečer.
The 1pl aorist of 'doći' is 'dođosmo', with the connecting -o-, not '*dođesmo'.
Rekoh ti da ne ideš.
Rekao ti da ne ideš.
The 1sg aorist is 'rekoh'; 'rekao' is the l-participle and needs an auxiliary.

Common mistakes

Confusing l-participle with the aorist
Rekao ti da odeš.
Rekoh ti da odeš.
The aorist is a finite one-word form (rekoh); the l-participle (rekao) needs an auxiliary.
Wrong connecting vowel in plural
Dođesmo kući.
Dođosmo kući.
Verbs like 'doći' take -osmo/-oste/-oše in the plural: dođosmo.

B1Verb tenses

Imperfekt — Formation & Use

Imperfekt — tvorba i uporaba

The imperfekt is a simple (one-word) past built from imperfective verbs to describe an ongoing or repeated past action — the background against which something else happened. It is the aorist's imperfective counterpart, and it sounds archaic or literary today; in modern Croatian the imperfective perfekt ('govorio sam') does the same job. You'll meet it mostly in older literature, the Bible, and elevated style. The form to know is the imperfekt of 'biti' — bijah, bijaše, bijasmo… (or the short bjeh, bješe). As a learner you mainly need to recognise the imperfekt and understand it marks duration in the past.

Key rule

The imperfekt is a one-word past formed from imperfective verbs (-ah/-jah; biti → bijah/bjeh) marking an ongoing or repeated past action; it is archaic/literary, replaced in speech by the imperfective perfekt.

Examples

Sunce sjaše, a ptice pjevahu.
Sunce sja, a ptice pjevaju.
In a past-tense narrative the imperfekt (sjaše, pjevahu) marks ongoing background; the present tense would change the time frame.
Bijah mlad i bezbrižan.
Bijo mlad i bezbrižan.
The 1sg imperfekt of biti is 'bijah'; '*bijo' is not a form.
Dijete spavaše dok je majka radila.
Dijete spavaše dok je majka radio.
Imperfekt 'spavaše' for the background; the other clause's participle must agree (radila for a feminine subject).

Common mistakes

Building an imperfekt from a perfective verb
Napisah pismo cijeli dan.
Pisah pismo cijeli dan.
The imperfekt comes only from imperfective verbs; a perfective base heads the aorist instead.
Wrong biti-imperfekt form
Bijo sam mlad.
Bijah mlad.
The imperfekt is a one-word finite form 'bijah'; '*bijo sam' mixes a non-form with an auxiliary.

B1Verb tenses

Kondicional I — Formation (bih + l-participle)

Kondicional prvi (bih + glagolski pridjev radni)

Kondicional I (the present conditional) is how Croatian says 'I would…'. You build it with the conditional clitic 'bih' (bih, bi, bi, bismo, biste, bi) plus the l-participle, which agrees with the subject in gender and number — 'Radio bih' (I would work, masc.), 'Radila bih' (fem.). It's used for hypotheticals ('Da imam vremena, čitao bih'), polite requests ('Htio bih kavu'), wishes, and advice. The 'bih' clitic obeys second-position rules, so it usually leans on the first word: 'Ja bih to učinio' / 'To bih učinio'. Watch out: in casual speech people overuse 'bi' for all persons, but the standard keeps bih/bismo/biste distinct.

Key rule

Form the present conditional with the clitic auxiliary bih/bi/bi/bismo/biste/bi (in second position) plus the l-participle agreeing with the subject, for hypotheticals, polite requests, and advice.

Examples

Rado bih ti pomogao.
Rado bi ti pomogao.
The 1sg auxiliary is 'bih', not 'bi'; standard Croatian keeps the persons distinct.
Da imam vremena, čitala bih više.
Da imam vremena, čitao bih više.
The participle must agree with a feminine speaker: čitala, not čitao.
Mi bismo to rado učinili.
Mi bi to rado učinili.
The 1pl conditional auxiliary is 'bismo', not the colloquial leveled 'bi'.

Common mistakes

Leveling all persons to 'bi'
Mi bi došli.
Mi bismo došli.
Standard Croatian keeps bih/bismo/biste; only 3sg/3pl use 'bi'.
Participle not agreeing with subject
Ana bi došao.
Ana bi došla.
The l-participle agrees in gender and number; a feminine subject needs 'došla'.

Kondicional II — Past Counterfactual

Kondicional drugi

Kondicional II (the past conditional) is how Croatian says 'I would have…' — an unreal or missed possibility in the past. You build it from kondicional I of biti ('bio bih', 'bila bih') plus the l-participle of the main verb: 'Bio bih došao da sam znao' — 'I would have come if I had known.' Both participles agree with the subject. It is typically paired with a 'da'-clause stating the unreal past condition. In everyday Croatian it is receding: speakers very often use plain kondicional I instead ('Došao bih da sam znao'). So you should recognise it confidently and pair it with 'da', but kondicional I will usually do the job.

Key rule

Form the past conditional with kondicional I of biti (bio bih / bila bih…) plus the l-participle, both agreeing with the subject, usually paired with a 'da'-clause for an unreal past condition.

Examples

Da sam znao, bio bih došao.
Da sam znao, bio bi došao.
The 1sg auxiliary is 'bih', so 'bio bih došao'; 'bio bi došao' would be 3sg.
Da je imala vremena, bila bi nazvala.
Da je imala vremena, bio bi nazvala.
Both participles agree with a feminine subject: bila… nazvala, not 'bio'.
Bili bismo otišli da nije padala kiša.
Bili bi otišli da nije padala kiša.
The 1pl auxiliary is 'bismo', so 'bili bismo'; leveled 'bi' is non-standard.

Common mistakes

Leveling 'bih/bismo' to 'bi'
Mi bi bili došli.
Mi bismo bili došli.
Standard Croatian keeps bih/bismo/biste in kondicional II too.
biti-participle not agreeing
Ona bi bio došla.
Ona bi bila došla.
The auxiliary participle 'bio/bila/bilo' must match the subject's gender.

B1Verb tenses

Passive Voice — trpni pridjev (Kuća je sagrađena)

Pasiv s trpnim pridjevom

The periphrastic passive uses 'biti' plus the passive participle (trpni pridjev), which behaves like an adjective and agrees with the subject in gender and number: 'Kuća je sagrađena' (The house is/was built), 'Pisma su napisana'. The subject is the thing the action is done to; the doer, if mentioned at all, goes in 'od strane' + genitive ('od strane vlade'), but Croatian usually leaves it out. You can put it in different tenses by changing 'biti': present 'je napisana', past 'bila je napisana', future 'bit će napisana'. Croatian very often prefers the se-passive ('Kuće se grade') in speech, so the trpni passive is more formal and written.

Key rule

Form the periphrastic passive with 'biti' (in the needed tense) plus the passive participle, which agrees with the subject in gender and number; the agent is usually omitted or expressed with 'od strane' + genitive.

Examples

Kuća je sagrađena prošle godine.
Kuća je sagrađen prošle godine.
The participle agrees with feminine 'kuća': sagrađena, not 'sagrađen'.
Pisma su napisana i poslana.
Pisma su napisane i poslane.
'Pisma' is neuter plural, so the participle is 'napisana', not feminine-plural 'napisane'.
Vrata su bila zatvorena cijeli dan.
Vrata su zatvorili cijeli dan.
The passive uses biti + participle (su bila zatvorena); 'zatvorili' is the active l-participle.

Common mistakes

Participle not agreeing with subject
Kuća je sagrađen.
Kuća je sagrađena.
The passive participle is adjectival and agrees in gender/number with the subject.
Wrong participle for neuter plural
Pisma su napisane.
Pisma su napisana.
'Pisma' is neuter plural, taking -a (napisana), not feminine-plural -e.

B1Verb tenses

Se-Passive / Impersonal (Ovdje se govori hrvatski)

Pasiv i bezličnost s se

The se-construction is Croatian's everyday agentless passive and impersonal. With a verb plus the clitic 'se', you describe an action without naming who does it: 'Ovdje se govori hrvatski' (Croatian is spoken here), 'Kuće se grade brzo' (Houses are built quickly), 'Tu se ne puši' (No smoking here). When there's a patient, the verb agrees with it as if it were the subject ('Knjige se prodaju'). When there's no patient at all, the verb stays 3rd singular impersonal ('Ovdje se radi', 'Kako se kaže…?'). The clitic 'se' obeys second-position rules. This is much more common in speech than the biti-passive.

Key rule

Use verb + 'se' for an agentless passive (verb agrees with the patient: Knjige se prodaju) or impersonal (no patient, verb stays 3sg: Ovdje se radi); never add an explicit agent.

Examples

Ovdje se govori hrvatski.
Ovdje se govore hrvatski.
With the singular patient 'hrvatski' the verb is 3sg 'govori', not plural 'govore'.
Knjige se prodaju u toj trgovini.
Knjige se prodaje u toj trgovini.
The plural patient 'knjige' triggers plural agreement: prodaju, not 'prodaje'.
Tu se ne puši.
Tu se ne pušiti.
The impersonal se-form uses the finite present 'puši', never the infinitive.

Common mistakes

Verb not agreeing with the plural patient
Knjige se prodaje.
Knjige se prodaju.
In the passive-like se-construction the verb agrees with the patient as subject.
Pluralizing an impersonal (no-patient) verb
Ovdje se rade do kasno.
Ovdje se radi do kasno.
Without a patient the verb stays 3rd person singular.

B1Verb tenses

Passive Participle — Formation (-n / -t: napisan, otvoren)

Trpni pridjev — tvorba (-n, -t)

The passive participle (trpni pridjev) is the form you need for the passive and as an adjective: 'napisan' (written), 'otvoren' (open/opened), 'razbijen' (broken). Most verbs form it with -n (a-verbs: pisati → pisan, napisan), -en (many i/e-verbs: nositi → nošen, donijeti → donesen), or -t (short verbs: piti → pijen but biti-type and some monosyllables: oprati → opran, ubiti → ubijen, čuti → čuven; uzeti → uzet). Many -en forms trigger jotation, where the stem consonant softens: nositi → nošen, voziti → vožen, platiti → plaćen. Like any adjective, it then agrees with its noun in gender, number, and case.

Key rule

Form the passive participle with -n (pisan), -en (nošen, often with jotation: platiti→plaćen), or -t (uzet); it then declines and agrees like an adjective.

Examples

Pismo je napisano i poslano.
Pismo je napisan i poslan.
The participle agrees with neuter 'pismo': napisano/poslano, not masculine napisan/poslan.
Račun je plaćen.
Račun je platjen.
'platiti' jotates t→ć: plaćen, not '*platjen'.
Roba je vožena kamionom.
Roba je vozena kamionom.
'voziti' jotates z→ž: vožena, not '*vozena'.

Common mistakes

Missing jotation in -en participles
Račun je platjen.
Račun je plaćen.
The -en suffix triggers t→ć jotation: plaćen.
Wrong suffix (-en for an -t verb)
Torba je uzena.
Torba je uzeta.
Verbs like 'uzeti' form the participle with -t: uzet/uzeta.

B1Verb tenses

Choosing Past Tenses in Narrative

Izbor prošlih vremena u pripovijedanju

When you tell a story in Croatian, you choose among the past tenses to organize events. The perfekt ('radio sam', 'došao je') is the all-purpose past and the backbone of modern narration. The pluskvamperfekt ('bio sam već otišao') marks something that happened before another past event. The aorist ('dođe', 'reče') and imperfekt ('sjaše', 'pjevahu') belong to vivid or literary style — the aorist for punctual completed events, the imperfekt for ongoing background. In everyday storytelling you'll mostly use the perfekt, reaching for the pluskvamperfekt to show order; the aorist and imperfekt give a higher, more dramatic register you should recognise and use sparingly.

Key rule

Use the perfekt as the neutral narrative backbone, the pluskvamperfekt to mark an earlier past event, and the aorist/imperfekt only for a vivid or literary register — keeping the register consistent.

Examples

Ušao sam, sjeo i počeo čitati.
Uđoh, sjeo sam i počeo čitati.
Keep one register: either all perfekt or all aorist; mixing aorist 'uđoh' with perfekt breaks the narrative tone.
Kad sam stigao, vlak je već bio otišao.
Kad sam stigao, vlak je otišao.
To show the train left before arrival, use the pluskvamperfekt 'bio otišao', not a plain perfekt.
Sunce je sjalo dok smo hodali.
Sunce sjaše dok smo hodali.
In a neutral perfekt narration the background is the imperfective perfekt 'je sjalo'; the imperfekt 'sjaše' jars in a colloquial register.

Common mistakes

Mixing aorist and perfekt in one register
Uđoh i sjeo sam.
Uđoh i sjedoh. / Ušao sam i sjeo.
Keep the register consistent — either the vivid aorist throughout or the neutral perfekt throughout.
Plain perfekt where sequence needs the pluperfect
Kad sam došao, oni su otišli.
Kad sam došao, oni su već bili otišli.
To mark that they left before you arrived, use the pluskvamperfekt.

B1Verb usage

Motion Verbs — Prefixed Perfectives (doći, otići, ući, izaći)

Glagoli kretanja — prefigirani svršeni

Croatian does not have the determinate/indeterminate motion-verb system of Russian or Polish. Instead, direction is carried by a prefix added to a base motion verb. The perfective base -ći (as in doći, otići, ući, izaći, preći) names a single completed movement, and its imperfective partner ends in -laziti (dolaziti, odlaziti, ulaziti, izlaziti, prelaziti) for an ongoing or repeated movement. So do- means 'arrive here', od(t)- 'leave', u- 'enter', iz- 'exit', pre- 'cross'. You pick the prefix for the direction and the aspect (perfective vs imperfective) for whether the movement is one finished event or a process/habit. Learn these as ready pairs: doći/dolaziti, otići/odlaziti, ući/ulaziti, izaći/izlaziti, prijeći/prelaziti.

Key rule

Direction comes from the prefix (do-/od-/u-/iz-/pre-) and the perfective in -ći names one completed movement while its -laziti partner is the ongoing or habitual one.

Examples

Sutra ću doći k tebi.
Sutra ću dolaziti k tebi.
A single planned arrival is perfective doći; dolaziti would imply a repeated/habitual coming.
Svako jutro dolazim na posao biciklom.
Svako jutro dođem na posao biciklom.
A daily habit needs the imperfective dolaziti, not the single-event perfective doći.
Kad sam ušao u sobu, svi su šutjeli.
Kad sam ulazio u sobu, svi su šutjeli.
One completed entrance into the room is perfective ušao; ulazio describes an ongoing/repeated entering.

Common mistakes

Using the perfective for a habit
Svaki dan dođem kući u šest.
Svaki dan dolazim kući u šest.
Repeated, habitual motion requires the imperfective dolaziti; the perfective doći can only name a single completed arrival.
Wrong present stem of a -ći verb
Ja dolazim sutra, dođeš li ti?
Ja dolazim danas, hoćeš li ti doći sutra?
Doći has no present-tense meaning of its own; its present dođem heads the future or a da-clause, so a future plan is hoću doći / doći ću.

B1Verb usage

ići vs hodati / šetati (go vs walk)

ići, hodati, šetati

Three imperfective verbs cover 'going on foot' but they are not interchangeable. Ići is the general 'go' — by any means, in any direction (Idem u školu, Idem autobusom). Hodati is specifically 'to walk, to be on foot, to move on one's legs' (Dijete već hoda). Šetati (se) is 'to stroll, to take a walk' for pleasure, with no fixed destination (Šećemo parkom). So ići answers 'where to?', hodati describes the manner of moving (on foot), and šetati describes a leisurely activity. Croatian has no productive 'go often / go once' verb split; ići is just the all-purpose imperfective whose perfective directional partners are the prefixed -ći verbs (doći, otići).

Key rule

Use ići for directed going by any means, hodati for moving on foot as such, and šetati (se) for a leisurely walk — Croatian has no grammatical 'often/once' motion split.

Examples

Svake nedjelje šećemo uz more.
Svake nedjelje idemo uz more.
A leisurely walk along the sea is šetati; idemo would just say 'we go (there)' without the strolling sense.
Naša beba već sama hoda.
Naša beba već sama ide.
Learning to move on one's legs is hodati; ići cannot express the act of walking itself.
Idem na fakultet tramvajem.
Hodam na fakultet tramvajem.
Going by tram is ići; hodati specifically means on foot, so it clashes with tramvajem.

Common mistakes

Using hodati for going somewhere
Sutra hodam u Zagreb na konferenciju.
Sutra idem u Zagreb na konferenciju.
Travelling to a destination is ići; hodati only describes moving on foot, not a journey to a place.
Using ići for strolling
Poslije ručka volimo ići po parku.
Poslije ručka volimo šetati po parku.
A relaxed walk for pleasure is šetati; ići needs a goal and lacks the leisurely sense.

B1Verb usage

Motion Verbs + Direction Prepositions (u/na/k + case)

Glagoli kretanja + prijedlozi smjera

When a motion verb names a goal, Croatian distinguishes 'where to' from 'where'. Toward a place you use u or na + accusative (Idem u školu, Idem na posao); toward a person you use k(a) + dative (Idem k liječniku) or simply put the person in the dative-ish phrase. For 'home' there is a special adverb: kući means 'homeward / at home'. The same u/na that take the accusative for a goal take the locative for a static location (U školi sam). The choice between u and na is largely fixed by the noun: enclosed places and most countries/towns take u (u kući, u Zagreb), while open spaces, surfaces, events and some institutions take na (na stol, na koncert, na fakultet).

Key rule

For a goal use u/na + accusative (and k(a) + dative toward a person, kući for 'home'); the same u/na switch to the locative for a static location.

Examples

Idem u školu.
Idem u školi.
A goal of motion needs the accusative (u školu); the locative (u školi) means 'at school', a static location.
Putujemo na more svako ljeto.
Putujemo u more svako ljeto.
'To the seaside' is fixed as na more + accusative; u more would mean physically into the water.
Idem k liječniku.
Idem u liječnika.
Movement toward a person uses k(a) + dative (k liječniku), not u + a person.

Common mistakes

Locative instead of accusative for a goal
Idem u kući.
Idem u kuću.
A destination after a motion verb takes the accusative (u kuću); the locative (u kući) marks a static location.
Wrong u/na choice
Idemo u more na vikend.
Idemo na more za vikend.
'To the seaside' is the fixed na more; u more would mean into the water itself.

B1Verb usage

Reflexive se — Types (true / reciprocal / middle / inherent)

Vrste povratnih glagola

The little word se does many jobs, all with one form. (1) True reflexive: the subject acts on itself — Perem se ('I wash myself'), Oblačim se. (2) Reciprocal: two or more do it to each other — Vole se ('They love each other'), Gledaju se. (3) Middle/anticausative: something happens by itself, no agent — Vrata se otvaraju ('The door opens'), Led se topi. (4) Inherent: the verb simply always carries se and has no meaning without it — bojati se ('be afraid'), smijati se ('laugh'), nadati se ('hope'). The same se also builds the impersonal/passive (Ovdje se govori hrvatski), covered separately. Se is an enclitic and lands in the second position of the clause, just like other clitics.

Key rule

One clitic se covers true reflexive (self), reciprocal (each other), middle/anticausative (happens by itself) and inherent (verb only exists with se) — and it always sits in the second-position clitic slot.

Examples

Djeca se peru prije večere.
Djeca peru prije večere.
The true reflexive needs se ('wash themselves'); without it the verb would need a separate object.
Ana i Marko se već godinama poznaju.
Ana i Marko se već godinama poznaje.
Reciprocal with a plural subject takes a plural verb: poznaju, not singular poznaje.
Vrata su se sama otvorila.
Vrata su otvorila sama.
The anticausative/middle ('the door opened by itself') requires se; without it the verb sounds transitive and incomplete.

Common mistakes

Dropping se from an inherent verb
Sjećam tog ljeta.
Sjećam se tog ljeta.
Sjećati se is a reflexiva tantum: it has no meaning without se and governs the genitive.
Singular verb with a reciprocal plural subject
Oni se voli.
Oni se vole.
A plural subject takes a plural verb; the reciprocal se does not change agreement.

B1Verb usage

Modal Verbs — Full System (morati, moći, smjeti, trebati)

Modalni glagoli — cjelovito

Croatian has a tidy set of modal verbs, all followed by the infinitive in the standard language. Morati = 'must, have to' (Moram raditi). Moći = 'can, be able' (Mogu doći). Smjeti = 'may, be allowed' (Smijem li ući?). Trebati = 'need / should': it works two ways — personally with an infinitive (Trebam učiti = 'I should study') or impersonally with a dative person (Treba mi odmor = 'I need a rest'). Negation matters a lot: ne moram = 'I don't have to' (no obligation), but ne smijem = 'I must not / am not allowed'. Don't confuse them. With modals you keep the infinitive; da + present is colloquial and avoided in careful Croatian.

Key rule

Modals take the infinitive in standard Croatian, and negation is asymmetric: ne moram = 'don't have to' but ne smijem = 'must not'.

Examples

Moram danas završiti izvještaj.
Moram da završim danas izvještaj.
Standard Croatian uses morati + infinitive (završiti); moram da završim is colloquial/eastern.
Možeš li mi pomoći?
Možeš li me pomoći?
Pomoći governs the dative (mi), not the accusative (me).
Ovdje ne smiješ pušiti.
Ovdje ne moraš pušiti.
A prohibition is ne smjeti ('must not'); ne morati only means 'don't have to'.

Common mistakes

Confusing ne moram and ne smijem
Ne moraš dirati te žice — opasno je!
Ne smiješ dirati te žice — opasno je!
A prohibition is ne smjeti ('must not'); ne morati only removes an obligation ('don't have to').
da + present after a modal
Možemo da idemo sada.
Možemo ići sada.
Standard Croatian takes the infinitive after a modal; da + present is colloquial/eastern.

B1Verb usage

da + Present vs Infinitive — Standard Usage

da + prezent ili infinitiv — standardna uporaba

After modal, phase and wish verbs (morati, moći, htjeti, željeti, početi, voljeti), standard Croatian uses the infinitive: Moram ići, Želim spavati, Počinjem raditi. The construction da + present (Moram da idem, Želim da spavam) is colloquial and characteristic of the eastern variant; in careful Croatian you avoid it for the same subject. Da is correct and required when the two clauses have different subjects (Želim da ti dođeš = 'I want YOU to come') and after verbs of saying/thinking (Mislim da je dobro). There is also a colloquial purpose use idem da kupim ('I'm going to buy'), which standard Croatian renders as idem kupiti or with kako bih. So: same subject after a modal/wish verb → infinitive; different subject or reporting → da + present.

Key rule

Same-subject complements of modal/phase/wish verbs take the infinitive in standard Croatian; da + present is reserved for different subjects and for reporting/cognition clauses.

Examples

Želim naučiti svirati gitaru.
Želim da naučim svirati gitaru.
Same subject after željeti takes the infinitive in standard Croatian; da + present here is colloquial/eastern.
Želim da ti naučiš svirati gitaru.
Želim ti naučiti svirati gitaru.
Different subjects ('I want YOU to learn') require da + present; the infinitive cannot show the new subject.
Moram otići ranije.
Moram da odem ranije.
Modal + infinitive is standard; moram da odem is the eastern/colloquial variant.

Common mistakes

da + present for a same-subject modal complement
Hoću da spavam.
Hoću spavati.
With one subject, standard Croatian uses the infinitive after a wish/modal verb; da + present is eastern/colloquial.
Infinitive where subjects differ
Tražim svima šutjeti.
Tražim da svi šute.
When the complement has a different subject, da + present is obligatory; the infinitive cannot encode the new subject.

B1Verb usage

Verb Government with Prepositions (misliti na, čekati na)

Glagolska rekcija s prijedlozima

Many Croatian verbs demand a particular preposition plus a particular case, and the combination is fixed — you have to learn the verb together with its preposition, just like phrasal verbs in English. For example: misliti na nekoga ('think about someone', na + accusative), čekati na autobus or just čekati autobus ('wait for the bus'), brinuti se o djeci ('take care of the children', o + locative), ovisiti o vremenu ('depend on the weather', o + locative), vjerovati u sebe ('believe in oneself', u + accusative), ljutiti se na nekoga ('be angry at someone', na + accusative). The preposition is often different from what English uses, so never translate the English preposition directly — memorise the Croatian frame.

Key rule

Each governing verb selects a fixed preposition and case as a unit (misliti NA + acc, ovisiti O + loc, vjerovati U + acc) — learn the verb with its frame, never by translating the English preposition.

Examples

Stalno mislim na tebe.
Stalno mislim o tebi.
Misliti 'think about (someone)' governs na + accusative; misliti o exists but means 'have an opinion of', a different nuance.
Čekamo na autobus već pola sata.
Čekamo za autobus već pola sata.
Čekati takes na + accusative (or a bare accusative), never za.
Sve ovisi o vremenu.
Sve ovisi na vremenu.
Ovisiti governs o + locative; the English 'depend on' does not transfer to na.

Common mistakes

English preposition calqued onto Croatian
Ovisi na tebi.
Ovisi o tebi.
Ovisiti governs o + locative; 'depend on' must not be translated as na.
Wrong preposition with čekati
Čekam za rezultate.
Čekam rezultate. / Čekam na rezultate.
Čekati takes a bare accusative or na + accusative, never za.

B1Verb usage

Impersonal Constructions (treba, valja, ima + genitive)

Bezlične konstrukcije (treba, valja, ima)

Some Croatian sentences have no grammatical subject — the verb stays in an invariable 3rd-person-singular form. Treba učiti = 'one should study / it is necessary to study' (impersonal treba + infinitive). Valja reći = 'it should be said' (valja, a more formal 'one ought'). For existence and quantity, ima means 'there is/are' and takes the genitive: Ima kruha ('There is bread'), Ima ljudi koji…; its negative is nema + genitive: Nema vremena ('There's no time'), Nema problema. With these, do NOT put the thing in the nominative — ima/nema governs the genitive. Note the difference from personal trebati: Treba mi odmor ('I need a rest', with a dative person) versus impersonal Treba učiti ('one should study').

Key rule

Impersonal predicates keep an invariable 3sg form: treba/valja take the infinitive, and existential ima/nema govern the genitive (Ima kruha; Nema vremena), never the nominative.

Examples

Treba puno učiti za ovaj ispit.
Trebam puno učiti za ovaj ispit. (as a general statement)
The general 'one should study' is impersonal treba + infinitive; trebam would mean specifically 'I should'.
Ima kruha u košari.
Ima kruh u košari.
Existential ima governs the genitive (kruha), not the nominative (kruh).
Nema više mlijeka.
Nema više mlijeko.
Nema takes the genitive (mlijeka); this is the genitive of negation/existence.

Common mistakes

Nominative after ima/nema
Nema vrijeme za to.
Nema vremena za to.
Existential ima/nema governs the genitive (vremena), never the nominative.
Personal trebati for a general statement
Trebam paziti na cesti.
Treba paziti na cesti.
A general impersonal 'one should' is treba + infinitive; trebam wrongly restricts the statement to 'I'.
