Adjective–Noun Agreement — Nominative (suur maja, suured majad)
Omadussõna ühildumine — nimetav
In Estonian an attributive adjective AGREES with its noun in both NUMBER and CASE. In the nominative this means: a singular noun gets a singular adjective (suur maja = a big house), and a plural noun gets a PLURAL adjective with the same -d ending (suured majad = big houses). The adjective stands directly before the noun, and there is no gender to worry about — Estonian has none, so the same form ilus works for a boy, a girl or a thing (ilus poiss, ilus tüdruk, ilus auto). The one thing English speakers forget is the plural -d on the adjective: it is NOT suur majad but suured majad. So whenever the noun is plural in the nominative, the adjective copies the plural too: punased õunad (red apples), väikesed lapsed (small children), uued autod (new cars).
Key rule
An attributive adjective agrees with its noun in number AND case. In the nominative: singular adjective + singular noun (suur maja), plural adjective + plural noun (suured majad) — the -d goes on BOTH. No gender, so one form fits all.
Examples
- See on suur maja.See on suured maja.
A singular noun (maja) takes a singular adjective (suur), not the plural suured.
- Need on suured majad.Need on suur majad.
A plural noun (majad) needs a plural adjective: suured, not suur — the -d copies onto both.
- Mul on punased kingad.Mul on punane kingad.
Kingad is plural, so the adjective must be plural too: punased.
Common mistakes

Agreement in Genitive & Partitive (suure maja, suurt maja)
Ühildumine — omastav ja osastav
When a noun goes into the genitive or partitive, its adjective copies the SAME case. In the GENITIVE the adjective takes the genitive ending too: suur maja → suure maja (of the big house), ilus tüdruk → ilusa tüdruku. In the PARTITIVE the adjective takes the partitive ending: suur maja → suurt maja, külm vesi → külma vett (cold water). This matters a lot, because the partitive object and the total (genitive) object are everywhere in Estonian. So you say Ma ostsin suure maja (total: I bought THE big house, genitive) but Ma joon külma vett (partial: I drink some cold water, partitive). The adjective and noun simply travel together in the same case — never mix a nominative adjective with a partitive noun.
Key rule
The adjective takes the SAME case as its noun. Genitive: suure maja (total object / possession). Partitive: suurt maja, külma vett (partial object, after numbers, after negation). Never leave the adjective in the nominative.
Examples
- Ma ostsin suure maja.Ma ostsin suur maja.
A completed total object is genitive on BOTH words: suure maja, not suur maja.
- Ma joon külma vett.Ma joon külm vett.
The partial object is partitive on both: külma vett, not nominative külm.
- See on suure maja katus.See on suur maja katus.
Possession needs the genitive: suure maja katus (the big house's roof).
Common mistakes
Leaving the adjective in the nominative with a genitive noun
suur maja katussuure maja katusPossession is genitive on both words: suure maja katus.
Nominative adjective with a partitive object
Ma joon külm vett.Ma joon külma vett.Both adjective and noun take the partitive: külma vett.
Agreement in the Locative Cases (suures majas, suurel laual)
Ühildumine kohakäänetes
In the six place-cases (the -sse / -s / -st 'inside' series and the -le / -l / -lt 'on/surface' series), BOTH the adjective and the noun take the same ending. So 'in the big house' is suures majas (not suur majas), 'onto the high table' is kõrgele lauale, 'on the beautiful lake' is ilusal järvel. The pattern is regular: whatever case the noun is in, the adjective copies it exactly. This produces long matching endings that look repetitive but are correct: ilusas linnas (in a beautiful city), suurest majast (out of the big house), väikesele lapsele (to the little child). Just remember that the locative endings build on the GENITIVE stem of each word: suur → suure → suures; ilus → ilusa → ilusas.
Key rule
In the six place-cases both adjective and noun take the SAME locative ending, built on each word's genitive stem: suures majas (in the big house), kõrgele lauale (onto the high table), ilusast linnast (out of the beautiful city).
Examples
- Ma elan suures majas.Ma elan suur majas.
The inessive (in) goes on both words: suures majas, not nominative suur.
- Lapsed mängivad ilusas pargis.Lapsed mängivad ilus pargis.
Ilus must copy the inessive: ilusas pargis.
- Pane raamat kõrgele riiulile.Pane raamat kõrge riiulile.
The allative (onto) goes on both: kõrgele riiulile, not the genitive kõrge.
Common mistakes

suur majassuures majasThe adjective must copy the inessive ending: suures majas.
Genitive adjective instead of the locative
uue koolisuues koolisBoth words take the inessive -s here, not the genitive: uues koolis.
Plural Nominative Formation (-d: raamatud, majad)
Mitmuse nimetav
The nominative plural in Estonian is formed by adding -d — but NOT to the dictionary form. You add -d to the GENITIVE stem. So first find the genitive singular, then add -d: raamat (book) → genitive raamatu → plural raamatud; maja → maja → majad; auto → auto → autod; koer (dog) → koera → koerad. This is why the plural can look different from the dictionary word: õpetaja → õpetajad, but laps (child) → genitive lapse → plural lapsed, and tüdruk → tüdruku → tüdrukud. The -d plural is used for subjects (Raamatud on laual = the books are on the table) and for total plural objects (Ostsin raamatud = I bought the books). The single most useful tip: learn the genitive, and the plural is just genitive + d.
Key rule
Nominative plural = genitive stem + -d: raamat → raamatu → raamatud; laps → lapse → lapsed. It is the plural subject AND the plural total object (Ostsin raamatud), and an agreeing adjective copies it (suured majad).
Examples
- Raamatud on laual.Raamatd on laual.
The plural adds -d to the GENITIVE stem raamatu, giving raamatud — not -d to the bare nominative.
- Lapsed mängivad õues.Lapsd mängivad õues.
laps → genitive lapse → plural lapsed; the stem changes before -d.
- Mu sõbrad tulevad külla.Mu sõberad tulevad külla.
sõber gradates to sõbra in the genitive, so the plural is sõbrad, not *sõberad.
Common mistakes
Adding -d to the nominative instead of the genitive stem
raamatdraamatudThe plural attaches -d to the genitive stem raamatu: raamatud.
Not applying the genitive stem change
sõberadsõbradsõber → genitive sõbra; the plural is sõbra + d = sõbrad.
Plural Genitive & Partitive (raamatute, raamatuid)
Mitmuse omastav ja osastav
Beyond the -d plural you need two more plural forms: the GENITIVE plural and the PARTITIVE plural. The genitive plural usually ends in -te or -de and is the base for almost all other plural cases: raamat → raamatute, laps → laste, maja → majade. The partitive plural ends in -id, -sid, -e or -u and is used after numbers and for partial/indefinite plural objects: raamatuid, lapsi, maju, õunu. Compare: Mul on palju raamatuid (I have many books — partitive plural) vs raamatute kapp (the bookcase, literally 'cupboard of books' — genitive plural). These forms are partly unpredictable, so the smart approach is to learn each noun's plural genitive and plural partitive together with its singular three stems.
Key rule
Genitive plural = -te/-de (raamatute, laste), the base of all other plural cases. Partitive plural = -id/-sid/-e/-u (raamatuid, lapsi, maju), used after numbers, for partial plural objects, and after negation.
Examples
- Mul on palju raamatuid.Mul on palju raamatud.
After palju the plural object is partitive plural raamatuid, not the nominative plural raamatud.
- Toas on palju inimesi.Toas on palju inimesed.
Quantity word palju + partitive plural inimesi; the nominative plural inimesed is wrong here.
- See on laste mänguväljak.See on lapsete mänguväljak.
The genitive plural of laps is the irregular laste, not *lapsete.
Common mistakes
Nominative plural after a quantity word
palju raamatudpalju raamatuidQuantity words take the partitive plural: palju raamatuid.
Wrong genitive-plural ending
lapsetelastelaps has the irregular genitive plural laste, not *lapsete.
Plural in the Locative Cases (majades, kätele)
Mitmus kohakäänetes
Once you know the GENITIVE PLURAL, all the plural place-cases follow easily, because they are built on it. Take the genitive plural, drop the final -e, and add the case ending: maja → genitive plural majade → inessive majades (in the houses), allative majadele (onto the houses), elative majadest (out of the houses). The marker -de- or -te- runs through the whole plural: raamatutes (in the books), lastele (to the children), koolidest (from the schools), kätele (onto the hands). So the recipe is always the same: genitive plural stem + locative ending. An adjective with the noun agrees in the plural too: suurtes majades (in the big houses).
Key rule
Plural place-cases are built on the genitive plural stem: majades (in the houses), majadele (onto the houses), majadest (out of the houses); raamatutes, lastele, koolidest. The adjective agrees in the plural too: suurtes majades.
Examples
- Raamatud on riiulites.Raamatud on riiulis.
Plural inessive of riiul is riiulites (built on the genitive plural riiulite), not the singular riiulis.
- Ma ostan kingitusi sõpradele.Ma ostan kingitusi sõbrale.
Plural allative 'to friends' = sõpradele; sõbrale is the singular 'to a friend'.
- Lapsed mängivad väljakutel.Lapsed mängivad väljakul.
Plural adessive 'on the squares' = väljakutel; the singular väljakul means one square.
Common mistakes
Singular locative for a plural meaning
Raamatud on riiulis.Raamatud on riiulites.Several shelves → plural inessive riiulites, built on the genitive plural riiulite.
Building the plural locative on the wrong stem
majatesmajadesThe genitive plural is majade, so the inessive is majade + s = majades.
Comparative Degree (-m: suurem, ilusam)
Keskvõrre
To say 'bigger, smaller, more beautiful', Estonian adds -m to the GENITIVE stem of the adjective: suur → genitive suure → suurem (bigger); ilus → ilusa → ilusam (more beautiful); väike → väikese → väiksem (smaller); pikk → pika → pikem (longer/taller). There is no separate word like English 'more' — the -m does it all. To say 'than', use kui: Tallinn on suurem kui Tartu (Tallinn is bigger than Tartu); Ta on pikem kui mina (he is taller than me). A few common comparatives are irregular: hea → parem (better), halb → halvem (worse), palju → rohkem (more). The comparative itself can also decline like any adjective (suuremas majas = in a bigger house).
Key rule
Comparative = genitive stem + -m: suur → suurem, ilus → ilusam, väike → väiksem. 'Than' = kui (suurem kui Tartu) or the elative (minust suurem). No separate 'more'. Irregular: hea → parem, halb → halvem.
Examples
- Tallinn on suurem kui Tartu.Tallinn on rohkem suur kui Tartu.
The comparative is the single word suurem; Estonian does not add 'rohkem' (more) before the adjective.
- See raamat on huvitavam.See raamat on huvitavm.
-m attaches to the genitive stem huvitava, giving huvitavam, not *huvitavm.
- Ta on minust pikem.Ta on minust pikm.
pikk → genitive pika → pikem; -m on the genitive stem, not the bare root.
Common mistakes
Adding 'rohkem' before the adjective (English 'more')
rohkem suursuuremEstonian forms the comparative with -m, not with a separate 'more': suurem.
Attaching -m to the nominative stem
ilusmilusam-m goes on the genitive stem ilusa: ilusam.
Superlative Degree (kõige suurem / suurim)
Ülivõrre
Estonian has TWO ways to say 'the biggest, the most beautiful'. The easy, everyday way is ANALYTIC: put kõige in front of the comparative — kõige suurem (the biggest), kõige ilusam (the most beautiful), kõige parem (the best). kõige never changes; the comparative after it declines normally (kõige suuremas majas = in the biggest house). The second way is SYNTHETIC: add -im to the genitive stem — suurim (the biggest), ilusaim (the most beautiful), parim (the best, irregular). The synthetic form is shorter and more bookish; the kõige form is safe and always works. At A2, use kõige + comparative for everything and recognise the most common -im superlatives (parim, suurim, uusim).
Key rule
Superlative = kõige + comparative (kõige suurem, kõige parem) — the safe everyday form; or synthetic -im on the genitive stem (suurim, parim). kõige never changes; the comparative/-im form declines.
Examples
- See on kõige suurem maja.See on kõige suur maja.
kõige combines with the COMPARATIVE (suurem), not the positive (suur).
- Ta on klassi kõige parem õpilane.Ta on klassi kõige hea õpilane.
The superlative of hea is kõige parem (irregular comparative), not *kõige hea.
- Tallinn on Eesti suurim linn.Tallinn on Eesti kõige suurim linn.
Use EITHER the synthetic suurim OR kõige suurem — never kõige + the synthetic -im form together.
Common mistakes
kõige + positive instead of comparative
kõige suurkõige suuremkõige combines with the comparative form: kõige suurem.
Inflecting kõige
kõiges suuremas majaskõige suuremas majaskõige is invariable; only the comparative declines (suuremas).
The Genitive Stem - Foundation of Declension
Omastava tüvi - käänamise alus
In Estonian, ten of the fourteen cases are built on the GENITIVE STEM, not the dictionary (nominative) form. The genitive singular always ends in a vowel and has no case ending: raamat -> raamatu, sõber -> sõbra, jalg -> jala. Once you know the genitive, you just add the case endings to it: raamatu + le = raamatule, raamatu + s = raamatus, raamatu + ga = raamatuga. So the single most useful form to memorise for any new noun is NOT the nominative but the genitive. Notice consonant gradation often happens here too (jalg -> jala, the g weakens). The two forms that do NOT use the genitive stem are the nominative itself and the partitive, which can be unpredictable. Learn nouns as a pair: nominative + genitive.
Key rule
Ten of Estonia's fourteen cases are built on the GENITIVE STEM, so memorise every noun as a nominative+genitive pair (raamat, raamatu) and add case endings to the genitive: raamatule, raamatus, raamatuga - never to the nominative.
Examples
- Ma annan raamatu sõbrale.Ma annan raamatu sõberle.
The allative -le attaches to the genitive stem sõbra-, giving sõbrale, not to the nominative sõber.
- Auto seisab maja ees.Auto seisab majas ees.
The genitive (maja) precedes the postposition ees; the locative majas would mean 'in the house'.
- Ma panen võtme lauale.Ma panen võtme laudle.
Genitive of laud is laua (gradation d->∅), so the allative is lauale, not *laudle.
Common mistakes
Adding endings to the nominative instead of the genitive
Ma lähen sõberle.Ma lähen sõbrale.Case endings attach to the genitive stem (sõbra-), not the dictionary form sõber.
Ignoring consonant gradation in the genitive
Ma istun jalg peal.Ma istun jala peal.The genitive of jalg is jala (g drops), and the postposition governs the genitive.
The Partitive Stem - Unpredictable Forms
Osastava tüvi - ettearvamatus
The PARTITIVE singular (osastav) is the hardest form in Estonian because it has several possible endings and you cannot reliably predict which one a word takes. The common endings are: -t (vett, kätt, ööd), -d, -∅ (no ending, raamatut becomes raamatut but kohvi has bare -i? no: kohvi), or a vowel with no consonant (kohvi, autot). Some very frequent words are irregular: vesi -> vett, käsi -> kätt, öö -> ööd, laps -> last, mees -> meest, uus -> uut. Because the partitive is needed constantly - after numbers (kaks raamatut), after negation (ei joo vett), for partial objects and mass quantities (joon vett) - you simply have to learn it for each word. Treat it as the third form to memorise, alongside the nominative and genitive.
Key rule
The partitive singular is unpredictable (-t, -d, bare vowel, or irregular: vett, kätt, last, meest, ööd), so memorise every noun as a three-form set - nominative, genitive, partitive - because the partitive is needed after numbers, after negation, and for partial objects.
Examples
- Ma joon vett.Ma joon vesi.
Mass-quantity object is partitive; the partitive of vesi is the irregular vett, not the nominative.
- Mul on kaks last.Mul on kaks laps.
After numbers above one the noun is partitive singular; laps -> last.
- Ma näen kolme meest.Ma näen kolme mees.
Number governs the partitive singular; mees -> meest.
Common mistakes
Using the nominative after a number
Mul on kaks laps.Mul on kaks last.Numbers above one require the partitive singular; laps -> last.
Using the nominative for a mass object
Ma joon vesi.Ma joon vett.An indefinite quantity is a partitive object; vesi -> vett.
Three Stems Overview (Nominative, Genitive, Partitive)
Kolm tüve
Every Estonian noun has THREE basic forms you must learn together: the nominative (dictionary form), the genitive, and the partitive. Estonian dictionaries always list them as a triple: raamat - raamatu - raamatut; käsi - käe - kätt; laps - lapse - last. From these three you can build the whole case system. The nominative is the subject and the citation form. The GENITIVE is the stem for ten more cases (raamatule, raamatus, raamatuga). The PARTITIVE is the partial/quantity form (joon vett, kaks last). The plural is built from these stems too. So instead of memorising fourteen separate forms per noun, you learn just these three keys, and the rest follows. Whenever you meet a new noun, find its three stems first.
Key rule
Learn every Estonian noun as a three-form key - nominative, genitive, partitive (raamat - raamatu - raamatut) - because the nominative is the subject, the genitive is the stem for ten more cases, and the partitive is the partial/quantity form; the whole case grid hangs off these three.
Examples
- Raamat on huvitav.Raamatu on huvitav.
The subject is the nominative raamat, the first of the three stems.
- See on õpetaja raamat.See on õpetajat raamat.
Possession uses the genitive õpetaja, not the partitive.
- Ma loen raamatut.Ma loen raamat.
The ongoing/partial object is the partitive raamatut, the third stem.
Common mistakes
Learning only the nominative
Ma annan raamat sõber.Ma annan raamatu sõbrale.Without the genitive stem you cannot form the object or the allative; learn the three-form key.
Confusing genitive and partitive roles
Ma loen raamatu (intending ongoing 'reading').Ma loen raamatut.Ongoing/partial object = partitive (raamatut); completed = genitive (raamatu).
Translative Case (-ks) - Becoming / Change of State
Saav kääne - muutumine
The TRANSLATIVE case (saav kääne) ends in -ks and means BECOMING or TURNING INTO something. It answers kelleks? (into whom?) or milleks? (into what?). You add -ks to the genitive stem: arst -> arsti -> arstiks, õpetaja -> õpetajaks, külm -> külmaks. Use it with verbs of change and becoming: saama (to become), muutuma (to change into), jääma (to remain/get). 'Ta saab arstiks' = he becomes a doctor. 'Ilm muutub külmaks' = the weather turns cold. 'Jäin haigeks' = I got sick. Compare it with the essive (-na), which is the STATE you are already in (töötab õpetajana = works as a teacher) versus the translative, which is the CHANGE into a new state (õpib õpetajaks = is studying to become a teacher).
Key rule
The translative -ks means BECOMING or turning into something (saab arstiks, muutub külmaks, jäin haigeks); add -ks to the genitive stem, and contrast it with the essive -na, which is the existing state (töötab õpetajana).
Examples
- Ta tahab saada arstiks.Ta tahab saada arst.
Becoming requires the translative arstiks, not the nominative.
- Ilm muutub külmaks.Ilm muutub külm.
Change of state = translative külmaks.
- Ma jäin haigeks.Ma jäin haige.
jääma in the 'become/get' sense governs the translative haigeks.
Common mistakes
Using the nominative after saama (become)
Ta saab arst.Ta saab arstiks.Becoming requires the translative -ks: arstiks.
Confusing translative (becoming) with essive (being)
Ta õpib õpetajana.Ta õpib õpetajaks.Studying to become = translative -ks; working as = essive -na.
Translative for Purpose, Time-by and Set Phrases
Saav kääne - otstarve ja tähtaeg
Besides 'becoming', the translative -ks has several other very useful meanings. (1) PURPOSE / 'for': milleks? - 'Milleks see on?' (What is this for?), 'kingituseks' (as a gift), 'tasuks' (as payment). (2) DEADLINE / 'by a time': 'Töö peab valmis olema kella viieks' (The work must be ready by five o'clock), 'esmaspäevaks' (by Monday). (3) DURATION / 'for a period': 'Sõitsin Tartusse kaheks päevaks' (I went to Tartu for two days). (4) Many SET PHRASES: 'õnneks' (luckily), 'näiteks' (for example), 'kokkuvõtteks' (in summary), 'esiteks' (firstly). Note: 'in Estonian' (the language one speaks) is NOT the translative - it is 'eesti keeles' (inessive). Use the translative for purpose, deadlines and these fixed expressions.
Key rule
The translative -ks also means 'for / as' (kingituseks), 'by a deadline' (kella viieks, esmaspäevaks) and 'for a planned period' (kaheks päevaks), and appears in set phrases (õnneks, näiteks); but 'speak in Estonian' is the inessive eesti keeles, not the translative.
Examples
- See lill on sulle kingituseks.See lill on sulle kingitus.
Purpose 'as a gift' = translative kingituseks.
- Töö peab valmis olema kella viieks.Töö peab valmis olema kell viis.
Deadline 'by five o'clock' = translative kella viieks.
- Esita essee esmaspäevaks.Esita essee esmaspäeval.
Deadline 'by Monday' = translative; the adessive esmaspäeval would mean 'on Monday'.
Common mistakes
Using the nominative instead of the purpose translative
See on kingitus sulle (intending 'as a gift').See on sulle kingituseks.'As / for a gift' = translative kingituseks.
Using the adessive for a deadline
Tee see valmis esmaspäeval (intending 'by Monday').Tee see valmis esmaspäevaks.'On Monday' = adessive; 'by Monday' (deadline) = translative.
Terminative Case (-ni) - Up to / Until
Rajav kääne - kuni
The TERMINATIVE case (rajav kääne) ends in -ni and marks the LIMIT or end-point of something - 'up to', 'as far as', 'until'. It answers milleni? (up to what?), kauaks?/mis ajani? (until when?). Add -ni to the genitive stem: lõpp -> lõpu -> lõpuni (to the end), kael -> kaela -> kaelani (up to the neck), Tartu -> Tartuni (as far as Tartu). With time: 'kella viieni' (until five o'clock), 'õhtuni' (until evening), 'esmaspäevani' (until Monday). It is often paired with 'kuni' (until/up to): 'kuni lõpuni'. Use it for both spatial limits (jooksin metsani = I ran as far as the forest) and time limits (töötasin hilisõhtuni = I worked until late evening).
Key rule
The terminative -ni marks the end-point or limit 'up to / until' - spatial (Tartuni, kaelani) and temporal (kella viieni, õhtuni) - on the genitive stem; ranges combine it with the elative: esmaspäevast reedeni.
Examples
- Sõitsime Tartuni.Sõitsime Tartusse (intending 'as far as Tartu').
'As far as' the limit = terminative Tartuni; the illative Tartusse means 'into Tartu' as the destination.
- Töötasin kella viieni.Töötasin kella viis.
Time limit 'until five' = terminative kella viieni.
- Vesi ulatus kaelani.Vesi ulatus kael.
Spatial limit 'up to the neck' = terminative kaelani.
Common mistakes
Using the illative for a spatial limit
Sõitsime Tartusse (intending 'as far as Tartu').Sõitsime Tartuni.'As far as / up to' = terminative -ni; the illative -sse means the final destination 'into'.
Using the adessive for a time limit
Töötasin viiel (intending 'until five').Töötasin kella viieni.'Until' a time = terminative -ni.
Essive Case (-na) - As / In the Capacity Of
Olev kääne - kellena
The ESSIVE case (olev kääne) ends in -na and means 'AS' or 'in the role/capacity of' - the state someone is currently in. It answers kellena? (as whom?), millena? (as what?). Add -na to the genitive stem: õpetaja -> õpetajana (as a teacher), laps -> lapse -> lapsena (as a child), noor -> noore -> noorena (when young). 'Ta töötab arstina' = he works as a doctor. 'Lapsena elasin maal' = as a child I lived in the countryside. The key contrast is with the translative (-ks), which is BECOMING: 'õpib õpetajaks' (studying to become a teacher) vs 'töötab õpetajana' (works as a teacher). The essive is BEING/acting AS; the translative is BECOMING.
Key rule
The essive -na means 'as / in the capacity of' an existing state (töötab arstina, lapsena, väsinuna) on the genitive stem; contrast it with the translative -ks (becoming) and the nominative predicate (identity: ta on arst).
Examples
- Ta töötab arstina.Ta töötab arst.
Role/capacity 'as a doctor' = essive arstina, not the nominative.
- Lapsena elasin maal.Laps elasin maal.
Life stage 'as a child' = essive lapsena.
- Tulin koju väsinuna.Tulin koju väsinud.
Temporary state = essive väsinuna; the bare participle väsinud would be a predicate, not the 'in a tired state' adverbial.
Common mistakes
Using the nominative for a role/capacity
Ta töötab õpetaja.Ta töötab õpetajana.Role/function requires the essive -na: õpetajana.
Confusing essive (being) with translative (becoming)
Ta õpib õpetajana (intending 'to become a teacher').Ta õpib õpetajaks.Becoming = translative -ks; working/acting as = essive -na.
Comitative Case (-ga) - With / By Means Of
Kaasaütlev kääne - kellega, millega
The COMITATIVE case (kaasaütlev kääne) ends in -ga and is one of the most frequent Estonian cases. It has two main meanings. (1) ACCOMPANIMENT - 'with' a person: kellega? - 'Ma lähen sõbraga' (I go with a friend), 'Ta elab koeraga' (she lives with a dog). (2) INSTRUMENT / MEANS - 'with / by': millega? - 'Ma sõidan bussiga' (I travel by bus), 'Ma kirjutan pliiatsiga' (I write with a pencil), 'Ma lõikan noaga' (I cut with a knife). Add -ga to the genitive stem: sõber -> sõbra -> sõbraga, buss -> bussi -> bussiga, nuga -> noa -> noaga. The -ga ending never changes form (no vowel harmony in Estonian). A special quirk: when an adjective modifies the noun, only the noun takes -ga; the adjective stays in the genitive: 'suure autoga' (with a big car), not *suurega autoga.
Key rule
The comitative -ga means 'with' (accompaniment: sõbraga) and 'by means of' (instrument: bussiga, noaga) on the genitive stem; the ending never changes form, and with an adjective only the noun takes -ga while the adjective stays genitive (suure autoga).
Examples
- Ma lähen kinno sõbraga.Ma lähen kinno sõber.
Accompaniment 'with a friend' = comitative sõbraga.
- Ma sõidan tööle bussiga.Ma sõidan tööle buss.
Means of transport = comitative bussiga.
- Ta lõikab leiba noaga.Ta lõikab leiba nuga.
Instrument = comitative; the genitive of nuga is noa, so noaga.
Common mistakes
Using the nominative instead of the comitative for 'with'
Ma lähen sõber.Ma lähen sõbraga.Accompaniment 'with' = comitative -ga: sõbraga.
Using the nominative for an instrument
Ma kirjutan pliiats.Ma kirjutan pliiatsiga.Instrument/means = comitative -ga: pliiatsiga.
Consonant Gradation — Concept & Strong/Weak Grade
Astmevaheldus — sissejuhatus
Consonant gradation (astmevaheldus) is the heartbeat of Estonian word forms. Many words have TWO versions of their stem: a STRONG grade (tugev aste) and a WEAK grade (nõrk aste). As you add case or person endings, the stem flips between them, so a single word looks different across its forms: linn (city) but linna, jalg (leg) but jala, kott (bag) but koti. The strong grade usually appears in the nominative singular and the partitive singular; the weak grade typically appears in the genitive singular and most of the forms built on it. There are two kinds: QUANTITATIVE gradation, where a doubled stop shortens (kk→k, pp→p, tt→t), and QUALITATIVE gradation, where a consonant changes or disappears (b→v, d→j, g vanishes). You do not need to predict every word at once — but you must EXPECT the stem to change, and learn the genitive form alongside the dictionary form.
Key rule
Many Estonian stems alternate between a STRONG grade (nominative & partitive singular: linn, kott) and a WEAK grade (genitive and the cases built on it: linna, koti); always learn the genitive form, because that is where the grade flips.
Examples
- Linn on suur, aga linna keskus on väike.Linn on suur, aga linn keskus on väike.
Nominative linn (strong grade) but genitive linna (weak grade) before keskus; the genitive form is required for the possessor.
- See on minu jalg; ma murdsin jala ära.See on minu jalg; ma murdsin jalg ära.
Nominative jalg keeps the strong grade, but the total object 'jala' is genitive in the weak grade (g disappears).
- Kott on raske; koti sang on katki.Kott on raske; kott sang on katki.
Quantitative gradation: nominative kott (tt) → genitive koti (single t) before sang.
Common mistakes
Using the nominative (strong) stem where the genitive (weak) is required
Linn keskus on ilus.Linna keskus on ilus.A genitive attribute must be in the weak grade (linna), not the strong nominative stem (linn).
Inventing gradation for a word that has none
See on minu aut.See on minu auto.Many words (auto, raamat, kohv) never gradate; only specific stems alternate, so do not shorten or change a stable stem.
Quantitative Gradation: kk/k, pp/p, tt/t
Vältevaheldus — kk/k, pp/p, tt/t
Quantitative gradation (vältevaheldus) is the easiest type to see, because it is written. A word that ends its stem in a DOUBLED stop — kk, pp, tt — keeps the double letter in the STRONG grade (nominative and partitive singular) but drops to a SINGLE letter in the WEAK grade (genitive and everything built on it). So kk→k, pp→p, tt→t: sukk→suka, kapp→kapi, kott→koti, lukk→luku, sepp→sepa. The sound also shortens (from the overlong third quantity degree to the long second degree), but the spelling change is the reliable signal: one consonant in the genitive instead of two. This is extremely common, so once you spot a -kk, -pp or -tt noun, you can predict that its genitive will have a single k, p or t.
Key rule
A stem ending in kk, pp or tt keeps the double letter in the strong grade (nominative & partitive: kott, kappi) but shortens to a single k, p, t in the weak grade (genitive & cases built on it: koti, kapi).
Examples
- See sukk on katki; teise suka kaotasin ära.See sukk on katki; teise sukk kaotasin ära.
Genitive of sukk is suka (single k); the second total object 'suka' is in the weak grade.
- Kapp on suur; kapi uks ei käi kinni.Kapp on suur; kapp uks ei käi kinni.
Genitive kapi (single p) is required before uks; nominative kapp keeps pp.
- Kott on raske; koti põhi rebenes.Kott on raske; kott põhi rebenes.
Quantitative gradation: kott (tt) → genitive koti (single t).
Common mistakes
Keeping the double stop in the genitive
Kott põhi on katki.Koti põhi on katki.The weak grade shortens tt→t: genitive koti, not kott.
Shortening the stop in the partitive after a number
Ma ostsin kolm paki.Ma ostsin kolm pakki.The partitive singular keeps the strong grade (pakki); numbers govern the partitive, which is strong here.
Qualitative Gradation: k/g, p/b, t/d Change & Loss
Laadivaheldus — k/g, p/b, t/d
Qualitative gradation (laadivaheldus) is harder than the doubling type, because the consonant CHANGES its quality or disappears rather than just shortening. Single stops weaken in the weak grade: the letters g, b, d in the strong stem often turn into v, j, or vanish, and stems with k, p, t can lose them too. Common patterns: leib→leiva (b→v), selg→selja and jalg→jala (g→j or g lost), sada→saja (d→j), sild→silla (d→l). The strong grade still lives in the nominative and partitive singular, while the weak grade shows up in the genitive. These changes are less predictable from spelling than kk/pp/tt, so the safest strategy is to learn each word's genitive form by heart.
Key rule
In qualitative gradation a single stop changes or disappears in the weak grade (genitive): b→v (leib→leiva), g→j or lost (selg→selja, jalg→jala), d→j/l/lost (sada→saja, sild→silla) — learn each word's genitive by heart.
Examples
- Leib on värske; leiva koorik on krõbe.Leib on värske; leib koorik on krõbe.
Genitive of leib is leiva (b→v) before koorik; the nominative leib stays strong.
- Selg valutab; selja taga on uks.Selg valutab; selg taga on uks.
Genitive selja (g→j) is required by the postposition taga; nominative selg keeps the g.
- Mu jalg on haige; jala sõrmed on külmad.Mu jalg on haige; jalg sõrmed on külmad.
Genitive of jalg is jala (g lost); the attribute must be in the weak grade.
Common mistakes
Keeping the strong consonant in the genitive
Leib koorik on krõbe.Leiva koorik on krõbe.The weak grade changes b→v: genitive leiva, not leib.
Failing to drop g in the weak grade
Jalg sõrmed valutavad.Jala sõrmed valutavad.In the weak grade g of jalg disappears: genitive jala.
Gradation: Loss of d / t (sõda → sõja, tuba → toa)
Astmevaheldus — d, t kadu
The most opaque kind of gradation is when a stop simply DISAPPEARS between vowels, and the remaining vowels squeeze together. Here the weak grade has no visible consonant where the strong grade had one: sõda→sõja (d becomes j), tuba→toa (b vanishes, ua→oa), sada→saja, pidu→peo (d lost, contraction), nägema→näen (g lost). In verbs this is just as common: lugema→loen (g lost in the present), pidama→pean. Because a whole consonant goes missing and the vowels merge, you usually cannot reconstruct the form from the dictionary entry — these are the cases you must memorise individually. Expect a short, contracted weak grade and a fuller strong grade.
Key rule
In the most opaque gradation a stop disappears entirely and the vowels contract: tuba→toa, sõda→sõja, pidu→peo (nouns); lugema→loen, pidama→pean (verbs) — these must be memorised, not predicted.
Examples
- Tuba on soe; toa põrand on puhas.Tuba on soe; tua põrand on puhas.
Genitive of tuba is toa (b lost, u+a → oa), not 'tua'.
- Sõda on kohutav; sõja lõpp tuli alles 1945.Sõda on kohutav; sõda lõpp tuli alles 1945.
Genitive of sõda is sõja (d→j); the attribute must be in the weak grade.
- Pidu oli lõbus; peo lõpus tantsisime.Pidu oli lõbus; pidu lõpus tantsisime.
Genitive of pidu is peo (d lost, contraction); 'pidu lõpus' would be ungrammatical.
Common mistakes
Keeping the consonant in the weak grade
Sõda lõpp tuli hilja.Sõja lõpp tuli hilja.In the weak grade d→j: genitive sõja, not sõda.
Wrong vowel after consonant loss
Tua põrand on puhas.Toa põrand on puhas.When b drops in tuba the vowels contract to oa: genitive toa, not 'tua'.
Gradation with s / h and Other Consonants (käsi → käe)
Astmevaheldus — s, h jt
Beyond the stop alternations, a small but very common set of words gradates around s and h, often with surprising results. The word käsi (hand) loses its s in the genitive: käe — but its partitive is kätt, with a doubled t! Other key examples: uks→ukse (s kept, vowel added), mees→mehe (s→h), kuus→kuue (s lost), küüs→küüne, vesi→vee, susi→soe. These are mostly high-frequency core words, so even though they are irregular you will meet them constantly. Because the changes are dramatic — a sound becoming h, or disappearing, or a different consonant appearing in the partitive — each of these words is best memorised as a full set: nominative, genitive and partitive together.
Key rule
A frequent class of s-stems gradates dramatically: käsi→käe (gen)→kätt (part), vesi→vee→vett, mees→mehe→meest, uks→ukse→ust — learn the nominative, genitive AND partitive together, since none predicts the others.
Examples
- Mu käsi valutab; käe sõrmed on külmad.Mu käsi valutab; käsi sõrmed on külmad.
Genitive of käsi is käe (s lost); the attribute must be in the weak/genitive grade.
- Ma pesen käsi; pesen kätt seebiga.Ma pesen käsi; pesen käe seebiga.
The partitive singular of käsi is kätt (double t), not the genitive käe.
- Vesi on külm; klaasis on vett.Vesi on külm; klaasis on vee.
Partitive of vesi is vett (the mass object), not the genitive vee.
Common mistakes
Using the nominative stem as the genitive
Käsi sõrmed on külmad.Käe sõrmed on külmad.Genitive of käsi is käe (s lost), needed for the attribute.
Confusing the partitive with the genitive
Ma pesen käe.Ma pesen kätt.The partitive of käsi is kätt (double t); käe is the genitive.
Which Case Takes Which Grade (Nominative vs Genitive)
Tugev ja nõrk aste käänetes
Once you know a word gradates, the next question is WHICH case takes which grade. The reliable rule for most gradating words: the NOMINATIVE singular has the strong grade, the GENITIVE singular has the weak grade, and the PARTITIVE singular usually has the strong grade too. Then every case built on the genitive stem (inessive, elative, allative, adessive, ablative, comitative, etc.) inherits the WEAK grade, because they are all formed from the genitive. So for jalg: nominative jalg (strong), partitive jalga (strong), genitive jala (weak), inessive jalas (weak), adessive jalal (weak). A useful shortcut: 'strong in nominative and partitive, weak everywhere built on the genitive'. The short illative is an exception — it often re-strengthens (jalga, tuppa, lukku).
Key rule
For most gradating words the nominative and partitive singular are STRONG, while the genitive singular and every case built on it (inessive, allative, adessive, comitative…) are WEAK — but the short illative often re-strengthens (jalga, tuppa).
Examples
- Jalg valutab, aga ma kõnnin jalal edasi.Jalg valutab, aga ma kõnnin jalgal edasi.
Adessive builds on the weak genitive stem jala-: jalal, not the strong 'jalgal'.
- Linn on suur; ma elan linnas.Linn on suur; ma elan linnnas.
Inessive linnas builds on the genitive stem linna-; the nominative is linn.
- See on kott; raamat on kotis.See on kott; raamat on kottis.
Inessive builds on the weak genitive stem koti-: kotis (single t), not 'kottis'.
Common mistakes
Using the strong stem in genitive-based cases
Ma kõnnin jalgal.Ma kõnnin jalal.Local cases build on the weak genitive stem jala-: adessive jalal.
Doubling the consonant in the inessive
Raamat on kottis.Raamat on kotis.The inessive uses the weak stem koti-: kotis (single t).
Gradation in Verb Forms (hakkan → hakata, loen → lugeda)
Astmevaheldus pöördsõnades
Gradation does not only affect nouns — it splits a VERB's forms into two grades as well, and the dividing line runs between the two infinitives. For a gradating verb, the ma-infinitive and the present tense usually share one grade, while the da-infinitive often takes the other. Classic pairs: hakkama → hakkan (present, strong kk) but hakata (da-infinitive, weak k); lugema → loen (present, g lost) but lugeda (da-infinitive, g kept); andma → annan but anda; hüppama → hüppan but hüpata. Sometimes the strong grade is in the present, sometimes in the da-infinitive, so you must learn the verb's principal parts (ma-infinitive, present 1sg, da-infinitive, past). The good news: once you know whether the present is strong or weak, the rest of the present tense follows it.
Key rule
In a gradating verb the present tense and the da-infinitive stand in OPPOSITE grades — sometimes the present is strong (hakkan / hakata), sometimes the da-infinitive is (loen / lugeda) — so learn each verb's principal parts.
Examples
- Ma hakkan kohe tööle; ma pean hakkama tööle.Ma hakkan kohe tööle; ma pean hakata tööle.
After pidama the ma-infinitive is required: hakkama (strong), not the da-infinitive hakata.
- Ma loen raamatut; mulle meeldib lugeda.Ma lugen raamatut; mulle meeldib loeda.
Present loen (weak, g lost) vs da-infinitive lugeda (strong, g kept) — the two grades are opposite.
- Ma hakkan õppima eesti keelt.Ma hakkan õpida eesti keelt.
Hakkama takes the ma-infinitive (õppima), not the da-infinitive.
Common mistakes
Using the da-infinitive after pidama/hakkama
Ma hakkan õpida.Ma hakkan õppima.Hakkama governs the ma-infinitive (õppima), which carries its own grade.
Keeping the full stem in the present
Ma lugen raamatut.Ma loen raamatut.The present of lugema is weak (g lost): loen.
Verbs & Nouns Without Gradation
Astmevahelduseta sõnad
Not every Estonian word gradates — and knowing when NOT to apply gradation is just as important as knowing when to. Many extremely common words have a STABLE stem that never changes grade: the verbs elama (elan, elada), mängima (mängin, mängida), küsima (küsin, küsida) do not gradate; the nouns raamat (raamatu), auto (auto), kohv (kohvi), pere (pere), tee (tee) keep one stem throughout. Words with a stable consonant cluster (like the l in elama, the ng in mängima) simply add endings without any change. The practical lesson: do not 'correct' a stable stem by inventing a weak grade — keep raamat as raamatu, auto as auto, elan as elad. Gradation is a property of SPECIFIC words, not a blanket rule.
Key rule
Many high-frequency words never gradate — raamat→raamatu, auto→auto, elama→elan→elada keep one stem throughout — so do not invent a weak grade; gradation belongs to specific words, not to all of them.
Examples
- Raamat on huvitav; raamatu kaas on punane.Raamat on huvitav; raama kaas on punane.
Raamat does not gradate: genitive raamatu (stable t), never 'raama'.
- See on minu auto; auto värv on sinine.See on minu auto; aut värv on sinine.
Auto has a stable stem: genitive auto, not 'aut'.
- Ma elan Tartus; sa elad Tallinnas.Ma elan Tartus; sa elsad Tallinnas.
Elama does not gradate: elan, elad, elab keep the stable l.
Common mistakes
Inventing a weak grade for a stable noun
Raama kaas on punane.Raamatu kaas on punane.Raamat does not gradate; the genitive is raamatu, with the stem intact.
Shortening a stable stem like auto
See on aut värv.See on auto värv.Auto keeps its stem in all forms: auto, never 'aut'.
Palatalisation Across Forms (kott vs koti)
Palatalisatsioon vormides
Palatalisation (palatalisatsioon) is a 'soft' colouring that a consonant gets when an i once stood next to it. It is NOT written in standard Estonian, but it is real and meaningful in speech. The same letters can be pronounced soft or hard depending on the word: pal'k (a beam) vs palk (wages) differ only by palatalisation; sool 'intestine' (gen soole) has a soft l, sool 'salt' (gen soola) a hard l; koli (junk) has a soft l, kola (clatter) a hard l. Be careful not to confuse this with consonant length: kott and koti differ mainly because kott has an OVERLONG tt while koti has a short t — that is QUANTITY (välde), not palatalisation. For an A2 learner the goal is mostly RECOGNITION: know that two written-identical words may sound different, that this softness lives near i and j, and that you cannot see it on the page — you learn it by listening.
Key rule
Palatalisation is an unwritten 'soft', i-coloured pronunciation of consonants (palk 'wages' vs pal'k 'beam'; sool 'salt' hard l vs sool 'intestine' soft l) tied to a historical front i in the stem — you can hear it but not see it, so learn it by ear; do not confuse it with consonant length (kott vs koti is QUANTITY, not palatalisation).
Examples
- Palk tuleb iga kuu; palga eest ostan toidu.Palk tuleb iga kuu; palgi eest ostan toidu.
Here 'palk' means 'wages', whose genitive is palga; palgi is the genitive of the homograph pal'k 'beam' (palatalised l), so it is the wrong word. The two homographs sound different through palatalisation (heard, not written) but only their genitive forms (palga vs palgi) reveal the contrast on the page.
- Raamat on kotis.Raamat on kots.
The inessive kotis is built on the weak-grade stem koti-; the spelling stays kotis (the single t is short — quantity, not palatalisation).
- Kott ja koti erinevad kaashääliku pikkuse poolest.Kott ja koti erinevad palatalisatsiooni poolest.
The difference between kott and koti is one of QUANTITY (overlong tt vs short t), i.e. vältevaheldus — it is NOT palatalisation, which is a separate, lexical softness.
Common mistakes
Picking the wrong genitive of homograph palk/pal'k
Palk tuleb iga kuu, aga palgi eest ei saa midagi.Palk tuleb iga kuu, aga palga eest ei saa midagi.'palk' here means 'wages', whose genitive is palga; palgi is the genitive of the homograph pal'k 'beam' (palatalised l). The two are distinguished in speech by palatalisation (heard, not written) and on the page only by their genitive forms.
Using a hard-l genitive for soft-l 'sool'
Sool on soolestiku osa ja soola haigus on ohtlik.Sool on soolestiku osa ja soole haigus on ohtlik.'intestine' (palatalised soft l) has the genitive soole; soola is the genitive of the homograph sool 'salt' (hard l). The two words differ in speech by palatalisation, which standard Estonian does not write.
Total Object vs Partial Object — Concept
Täis- ja osasihitis — mõiste
Estonian marks its direct object (sihitis) in two completely different ways depending on the MEANING. A 'total object' (täissihitis) signals that the whole thing is fully affected and the action is completed: it goes into the genitive in the singular (Ostsin raamatu = I bought the/a book — all of it, done) and the nominative in the plural (Ostsin raamatud). A 'partial object' (osasihitis) signals an ongoing, incomplete, negated, or quantitatively vague action: it always goes into the partitive (Lugesin raamatut = I was reading a book; Ma ei osta raamatut = I am not buying a book). English has none of this — 'a book' looks the same whether you read it or finished it — so you must learn to choose the case from how complete and how bounded the action is.
Key rule
Choose object case by meaning: completed & whole = total object (genitive in the singular, nominative in the plural); ongoing, mass, vague, or negated = partial object (always partitive).
Examples
- Ostsin raamatu.Ostsin raamat.
A completed singular total object is the GENITIVE (raamatu), not the bare nominative raamat.
- Lugesin raamatut.Lugesin raamatu.
An ongoing/process reading takes the partitive (raamatut); the genitive raamatu would mean 'read it to the end'.
- Ma ei ostnud raamatut.Ma ei ostnud raamatu.
Under negation the object MUST be partitive (raamatut), never genitive.
Common mistakes
Using the bare nominative for a singular total object
Ostsin raamat.Ostsin raamatu.A completed singular object is the GENITIVE (raamatu), not the dictionary/nominative form.
Using the genitive object under negation
Ma ei lugenud raamatu.Ma ei lugenud raamatut.Negation always forces the partitive object, overriding completion.
Total Object in the Singular = Genitive (Ostsin raamatu)
Täissihitis ainsuses — omastav
When a singular object is completely affected and the action is finished, Estonian puts it in the GENITIVE — the same form you use for possession. Ostsin raamatu (I bought the book), Sõin õuna (I ate the/an apple), Lugesin kirja läbi (I read the letter through). The object looks identical to the genitive: raamat → raamatu, õun → õuna, kiri → kirja, auto → auto. This often surprises learners, because the genitive is 'the of-form', yet here it marks a fully consumed object. It is NOT the dictionary/nominative form (not *Ostsin raamat) and NOT the partitive (raamatut would mean an ongoing or negated reading). Estonian differs from Finnish here: Finnish would use an accusative -n, but Estonian simply re-uses the genitive. Whenever you can say 'and now it's done — the whole thing', use the genitive.
Key rule
An affirmative, completed singular object goes into the GENITIVE (Ostsin raamatu, Sõin õuna, Lugesin kirja läbi) — not the nominative, not the partitive.
Examples
- Ostsin raamatu.Ostsin raamat.
The completed singular object is the genitive raamatu, not the bare nominative raamat.
- Sõin õuna ära.Sõin õun ära.
Genitive õuna marks the fully-eaten apple; õun is the nominative.
- Lugesin kirja läbi.Lugesin kiri läbi.
The finished reading takes the genitive kirja; kiri is the nominative.
Common mistakes
Using the nominative for a completed singular object
Ostsin auto... ostsin raamat.Ostsin raamatu.A finished singular object is the GENITIVE (raamatu), never the dictionary/nominative form.
Using the partitive for a clearly finished action
Lugesin raamatut läbi.Lugesin raamatu läbi.With läbi (completion) the object is the genitive total object; the partitive contradicts the completion.
Total Object in the Plural = Nominative (Ostsin raamatud)
Täissihitis mitmuses — nimetav
In the SINGULAR a completed object is the genitive (Ostsin raamatu), but in the PLURAL a completed object is the NOMINATIVE plural — the -d form: Ostsin raamatud (I bought the books), Sõin õunad ära (I ate the apples). This means the total object plural looks exactly like a plural subject (raamatud, õunad, lapsed), which surprises learners. The clause must be affirmative and the action complete; the whole set is fully affected. Under negation it switches to the plural partitive (Ma ei ostnud raamatuid), and for an ongoing or indefinite plural amount you also use the partitive (Lugesin raamatuid = I was reading books / some books). So: completed whole set in the plural → nominative plural -d; everything else → partitive plural.
Key rule
An affirmative, completed PLURAL object is the NOMINATIVE PLURAL (-d): Ostsin raamatud, Sõin õunad ära — not the genitive (that is singular) and not the partitive (that is negated/ongoing/indefinite).
Examples
- Ostsin raamatud.Ostsin raamatute.
The completed plural object is the nominative plural raamatud, not the genitive plural raamatute.
- Sõin õunad ära.Sõin õunu ära.
A completed whole set is the nominative plural õunad; the partitive plural õunu suggests an indefinite/ongoing amount.
- Pesin nõud ära.Pesin nõusid ära.
All the dishes done = nominative plural nõud; nõusid is the partitive plural.
Common mistakes
Using the genitive plural for a completed plural object
Ostsin raamatute.Ostsin raamatud.The plural total object is the NOMINATIVE plural (raamatud); the genitive plural raamatute is never an object.
Using the partitive plural for a completed whole set
Sõin õunu ära.Sõin õunad ära.A fully-eaten, definite set of apples is the nominative plural õunad.
Partitive Object under Negation (Ma ei ostnud raamatut)
Osasihitis eituses
Negation is the strongest object rule in Estonian: whenever the clause is negative, the object goes into the PARTITIVE — no matter how complete or bounded the action would otherwise be. Ostsin raamatu (I bought the book, genitive) but Ma ei ostnud raamatut (I did not buy a/the book, partitive). The same applies in every tense and to every object: Ma ei söö leiba (I don't eat bread), Ta ei näinud filmi (he didn't see the film), Me ei ostnud autot (we didn't buy a car). It also applies in the plural: Ma ei ostnud raamatuid. The negator ei never changes form (ma ei…, ta ei…); the verb loses its personal ending, and the object turns partitive. This is the single most reliable object rule — if there is an ei, look for the partitive.
Key rule
Any negated clause takes a PARTITIVE object, overriding completion and definiteness: Ostsin raamatu → Ma ei ostnud raamatut; the negator ei never changes form.
Examples
- Ma ei ostnud raamatut.Ma ei ostnud raamatu.
Negation forces the partitive raamatut; the genitive raamatu is only for affirmative completion.
- Ta ei söö leiba.Ta ei söö leiva.
Negated object = partitive leiba; the genitive leiva is wrong under ei.
- Me ei näinud filmi.Me ei näinud film.
Even a 'whole film' becomes partitive filmi under negation; not the nominative film.
Common mistakes
Keeping the genitive object under negation
Ma ei ostnud raamatu.Ma ei ostnud raamatut.Negation always switches the object to the partitive (raamatut).
Using the nominative object under negation
Ta ei näinud film.Ta ei näinud filmi.The negated object is partitive filmi, never the bare nominative.
Partitive for Ongoing / Incomplete Action (Lugesin raamatut)
Osasihitis kestva tegevuse korral
Even in an affirmative sentence, the object is PARTITIVE when the action is ongoing, in progress, or not carried to a result. Compare Lugesin raamatut (I was reading a book / I read at a book — process, maybe unfinished) with Lugesin raamatu läbi (I read the whole book — finished). The partitive describes the activity without an endpoint; the genitive (total object) describes a completed, bounded result. This is how Estonian expresses the difference English shows with 'was reading' vs 'read (finished)'. Many everyday descriptions of activity therefore use the partitive: Kirjutasin kirja (I was writing a/the letter), Ehitasin maja (I was building a/the house, working on it), Vaatasin telekat (I was watching TV). Add a resultative particle (läbi, ära, valmis) or a clear result, and you switch to the genitive total object.
Key rule
An affirmative action seen as a PROCESS (ongoing, no asserted endpoint) takes a partitive object; add completion (a result or a particle like läbi/ära/valmis) and it becomes the genitive total object.
Examples
- Lugesin raamatut.Lugesin raamatu, aga ei lõpetanud.
An unfinished/ongoing reading is partitive (raamatut); the genitive raamatu asserts completion, which contradicts 'didn't finish'.
- Kirjutasin kirja.Kirjutasin kirja valmis, aga jätsin pooleli.
An ongoing/process writing is partitive (kirja); claiming completion with valmis and then saying 'left it unfinished' is a contradiction.
- Terve õhtu vaatasin telekat.Terve õhtu vaatasin teleka.
Duration + ongoing activity = partitive telekat; the genitive teleka is wrong for an open-ended activity.
Common mistakes
Using a total object for an ongoing action
Terve päeva ehitasin maja valmis.Terve päeva ehitasin maja.The learner means 'I was working on the house all day' (a process), but valmis ('finished') asserts completion. A process with no asserted result is partitive (maja, here syncretic with the genitive); valmis/the genitive force a completion reading that clashes with terve päeva.
Using the partitive with a resultative particle
Lugesin raamatut läbi.Lugesin raamatu läbi.läbi asserts completion, so the object must be the genitive total object raamatu.
Partitive for Indefinite Quantity (Jõin vett vs Jõin vee)
Osasihitis umbmäärase koguse korral
When the object is an unspecified amount — 'some water', 'bread', 'money' — Estonian uses the PARTITIVE: Jõin vett (I drank some water), Sõin leiba (I ate some bread), Ostsin piima (I bought milk). When you mean a definite, bounded amount or the whole specific thing, you use the total object instead: Jõin vee (I drank the (specific/whole) water), Sõin leiva (I ate the whole loaf). This is especially important for mass nouns (vesi, leib, raha, kohv, suhkur), which are partitive by default whenever the quantity is open. So the partitive answers 'some / an unspecified amount', while the genitive total object answers 'the whole specific portion'. With explicit measures the partitive also appears: klaas vett (a glass of water), tükk leiba (a piece of bread).
Key rule
An indefinite/open amount (esp. mass nouns: vett, leiba, raha) is the PARTITIVE object; a definite, bounded, fully-consumed amount is the genitive total object (vee, leiva). Measures and quantifiers govern the partitive (klaas vett, palju raha).
Examples
- Jõin vett.Jõin vee.
An unspecified amount of water = partitive vett; the genitive vee means a definite, whole portion.
- Sõin leiba.Sõin leib.
Some bread (mass, open amount) = partitive leiba; leib is the nominative, never an object here.
- Ostsin piima ja juustu.Ostsin piim ja juust.
Indefinite quantities of milk and cheese = partitive piima, juustu; not the nominatives.
Common mistakes
Using the genitive for an indefinite amount
Jõin vee.Jõin vett.For the intended 'I drank some water', an open, unspecified amount is the partitive vett; the genitive vee means a definite whole portion.
Using the nominative for a mass object
Sõin leib.Sõin leiba.Mass nouns as objects take the partitive (leiba); the nominative is only the subject/citation form.
Halfway there — imagine actually using all of this.

Verbs that Always Take a Partitive Object (armastama, ootama, otsima)
Osasihitist nõudvad verbid
Some Estonian verbs ALWAYS take a partitive object, no matter how 'complete' the situation seems, because their meaning is inherently open-ended (loving, waiting, fearing, searching never reach a 'finished whole'). The most important: armastama (to love), ootama (to wait for), otsima (to look for), kartma (to fear), aitama (to help), kuulama (to listen to), vaatama (to watch), mängima (to play), õppima (to study), tundma (to know/feel). So: Armastan sind (I love you), Ootan bussi (I'm waiting for the bus), Otsin võtmeid (I'm looking for the keys), Kardan koera (I'm afraid of the dog). These never take the genitive total object — *armastan sinu and *ootan bussi-as-genitive are wrong. Learn these verbs as 'partitive verbs': their object is partitive even in the affirmative and even when the situation is durative or specific.
Key rule
A class of verbs (armastama, ootama, otsima, kartma, aitama, kuulama, vaatama, õppima, mängima, tundma…) always takes a PARTITIVE object in the affirmative; the genitive total object is impossible with them.
Examples
- Armastan sind.Armastan sinu.
armastama always takes the partitive (sind); the genitive sinu is ungrammatical here.
- Ootan bussi.Ootan bussiga.
ootama governs the partitive object bussi (waiting FOR the bus); the comitative bussiga 'with the bus' is wrong.
- Otsin võtmeid.Otsin võtmed.
otsima takes the partitive (here plural võtmeid); the nominative plural võtmed would be a completed total object, impossible with otsima.
Common mistakes
Genitive total object with a partitive verb
Armastan sinu.Armastan sind.armastama inherently governs the partitive; the genitive object is impossible.
Nominative object with otsima/kartma
Otsin võtmed / Kardan koer.Otsin võtmeid / Kardan koera.These verbs require the partitive (võtmeid, koera), never the nominative.
Object with the Imperative (Ava uks!)
Sihitis käskivas kõneviisis
In a positive command (imperative), a completed singular object goes into the NOMINATIVE, not the genitive: Ava uks! (Open the door!), Tee töö ära! (Finish the work!), Pane raamat lauale! (Put the book on the table!). This is special: in a normal statement the same completed object would be the genitive (Avasin ukse, Tegin töö ära), but the 2nd-person singular imperative uses the nominative for the total object. The plural total object is the nominative plural as usual (Sulge aknad!). Negative commands behave like all negation — the object becomes partitive: Ära ava ust!, Ära tee tööd!, Ära unusta võtit!. So: positive imperative + whole singular object = nominative; negative imperative = partitive.
Key rule
A positive command takes the NOMINATIVE for a complete singular object (Ava uks!, Tee töö ära!) — not the genitive; a negative command (ära/ärge) takes the partitive (Ära ava ust!).
Examples
- Ava uks!Ava ukse!
A positive imperative uses the nominative for a complete singular object (uks), not the genitive ukse used in statements.
- Tee töö ära!Tee tööd ära!
A positive command with a completed object → nominative töö; the partitive tööd is only for negative or ongoing.
- Pane raamat lauale!Pane raamatu lauale!
Positive imperative total object = nominative raamat, not the genitive raamatu.
Common mistakes
Using the genitive object in a positive command
Ava ukse!Ava uks!A positive imperative uses the nominative for a complete singular object (uks), unlike the indicative.
Using the partitive in a positive command
Tee tööd ära!Tee töö ära!A completed positive command takes the nominative total object (töö); the partitive is for negation/ongoing.
Verb-Second after Fronted Adverbials (Homme lähen…)
Sõnajärg — öeldis teisel kohal
Estonian likes the finite verb in SECOND position (V2), like German and unlike English. In a neutral sentence the order is Subject–Verb: 'Ma lähen homme koju' (I'm going home tomorrow). But the moment you FRONT a time or place word for emphasis, the verb still wants to stay second, so the subject jumps AFTER the verb: 'Homme lähen ma koju' or, very naturally, with the pronoun dropped, 'Homme lähen koju'. So you do NOT say '*Homme ma lähen koju' in careful, written-style Estonian — that puts the verb in third place. The pattern is: fronted element + VERB + (subject) + rest. This inversion is most visible with adverbials like 'eile' (yesterday), 'homme' (tomorrow), 'siin' (here), 'siis' (then), 'nüüd' (now).
Key rule
Estonian is V2: the finite verb stays in second position. Front a time/place word and the subject moves AFTER the verb — 'Homme lähen ma koju' / 'Homme lähen koju', NOT '*Homme ma lähen koju' in careful style.
Examples
- Homme lähen ma koju.Homme ma lähen koju.
After a fronted adverbial the verb stays second; the subject moves after it (inversion).
- Eile käisin ma kinos.Eile ma käisin kinos.
Fronted 'eile' forces verb-second, so 'käisin' precedes the subject 'ma'.
- Eile käisin kinos.Eile käisin mina kinos rõhutult tavalises lauses.
The unstressed subject pronoun is normally dropped after inversion; the verb ending already shows '1sg'.
Common mistakes
Keeping subject before the verb after a fronted adverbial
Homme ma lähen koju.Homme lähen ma koju. / Homme lähen koju.Estonian is V2: a fronted time/place word forces subject–verb inversion.
Putting the verb in third position
Eile ma raamatut lugesin.Eile lugesin ma raamatut. / Eile lugesin raamatut.The finite verb must stay in the second slot after the fronted element.
Time Clauses with kui (when)
Ajalause — kui
To say 'when' about a time or an event, Estonian uses the subordinator 'kui'. 'Kui ma olin laps, elasin Tartus' = When I was a child, I lived in Tartu. The kui-clause can come first or second, but there is ALWAYS a comma between the two clauses: 'Kui ma tulin koju, sajas vihma' / 'Sajas vihma, kui ma tulin koju'. Estonian does not have a special future tense, so for future 'when' you use the present: 'Kui ma jõuan koju, helistan sulle' = When I get home, I'll call you. Note that the question word 'when?' is NOT kui — it is 'millal' ('Millal sa tulid?'). And 'kui' can also mean 'if' (open condition), so context tells you which: time vs condition.
Key rule
Temporal 'when' = kui + clause, with a comma between the clauses; verb order is normal SVO. Future 'when' uses the present tense ('Kui ma jõuan koju, helistan'). The QUESTION 'when?' is millal, not kui.
Examples
- Kui ma olin laps, elasin Tartus.Kui ma olin laps elasin Tartus.
A comma is obligatory between the kui-clause and the main clause.
- Sajas vihma, kui ma tulin koju.Sajas vihma kui ma tulin koju.
Even when the kui-clause comes second, the comma before 'kui' is required.
- Kui ma jõuan koju, helistan sulle.Kui ma jõuda koju, helistan sulle.
Future 'when' uses the present 'jõuan', not the da-infinitive 'jõuda'.
Common mistakes
Omitting the comma between the clauses
Kui ma tulin koju sajas vihma.Kui ma tulin koju, sajas vihma.Estonian requires a comma between a kõrvallause (kui-clause) and the main clause.
Using kui as the question word 'when?'
Kui sa sündisid?Millal sa sündisid?The interrogative 'when?' is millal; kui only introduces subordinate clauses.
Open Conditional with kui (if)
Tingimuslause — kui
The same word 'kui' that means 'when' also means 'if' for everyday, realistic conditions. 'Kui sajab, jään koju' = If it rains, I'll stay home. This is the OPEN (real) conditional: the condition might well happen, and both verbs are in the INDICATIVE present (no special mood needed). As with time clauses, the main clause can optionally start with 'siis': 'Kui sa tahad, (siis) tule kaasa' = If you want, come along. There is always a comma between the clauses. For a FUTURE result you still use the present tense: 'Kui ma jõuan õigeks ajaks, ostan piletid' = If I'm on time, I'll buy the tickets. Hypothetical/unreal 'if' (If I were rich…) uses the conditional mood (-ksin) and comes later; here we stay with simple, real conditions.
Key rule
Open (real) conditional = kui + indicative, comma, main clause (optionally with 'siis'). Both verbs are indicative present, even for a future result: 'Kui sajab, jään koju.' Unreal 'if' uses the -ksin conditional, taught later.
Examples
- Kui sajab, jään koju.Kui sajaks, jään koju.
An open, likely condition uses the indicative 'sajab', not the conditional 'sajaks'.
- Kui sa tahad, tule kaasa.Kui sa tahad tule kaasa.
A comma is obligatory between the kui-clause and the main clause.
- Kui ma saan palka, ostan uue telefoni.Kui ma saaksin palka, ostan uue telefoni.
Realistic future condition stays indicative present (saan), not conditional (saaksin).
Common mistakes
Using the conditional mood for a real condition
Kui sajaks, jään koju.Kui sajab, jään koju.An open/likely condition takes the indicative; -ks is for unreal hypotheticals.
Omitting the comma
Kui sa tahad tule kaasa.Kui sa tahad, tule kaasa.A comma is required between the kui-clause and the main clause.
Cause Connectors: sest, kuna, sellepärast et
Põhjuse sidesõnad
To say WHY, Estonian gives you a few 'because' words. 'Sest' is the everyday one and always introduces a reason that FOLLOWS the result: 'Ma jään koju, sest ma olen haige' = I'm staying home because I'm sick. 'Kuna' also means 'because/since' and is more flexible: it can open the sentence — 'Kuna ma olen haige, jään koju'. The longer 'sellepärast et' ('for the reason that') is emphatic. There is always a comma before the reason clause. Word order inside the reason clause is normal SVO: 'sest ma olen haige', not '*sest ma haige olen'. Don't confuse cause with consequence: 'sest/kuna' give the CAUSE; 'sellepärast / seega' give the RESULT.
Key rule
Cause = sest / kuna ('because, since'); the reason clause takes a comma before it and SVO order. Sest follows the main clause; kuna can also front it. Emphatic 'sellepärast, et …'. Don't mix these (cause) with seega/sellepärast = therefore (result).
Examples
- Ma jään koju, sest ma olen haige.Ma jään koju sest ma olen haige.
A comma is obligatory before the reason clause introduced by 'sest'.
- Kuna ma olen haige, jään koju.Sest ma olen haige, jään koju.
A fronted reason clause uses 'kuna'; 'sest' does not naturally open the sentence.
- Ma ei tulnud, sest mul oli palju tööd.Ma ei tulnud, sest ma palju tööd oli.
Use SVO inside the reason clause ('mul oli palju tööd'), not scrambled/verb-final order.
Common mistakes
Starting a sentence with 'sest'
Sest ma olen haige, jään koju.Kuna ma olen haige, jään koju. / Jään koju, sest ma olen haige.Sest introduces a following reason; a fronted reason clause uses kuna.
Omitting the comma before the reason clause
Ma jään koju sest olen haige.Ma jään koju, sest olen haige.A comma must precede the kõrvallause introduced by sest/kuna.
Contrast Connectors: aga, kuid, ent
Vastandavad sidesõnad
To say 'but', Estonian has a small family of words at different registers. 'Aga' is the everyday, spoken 'but': 'Ma olen väsinud, aga õnnelik' = I'm tired but happy. 'Kuid' means the same and is neutral-to-bookish, common in writing. 'Ent' is clearly literary/formal 'yet, however'. All three are COORDINATING (they join two equal clauses or phrases) and take a COMMA before them: 'Tahtsin tulla, aga ei jõudnud'. Unlike subordinators, they don't change the word order of what follows — it stays normal SVO. A useful relative: 'vaid' means 'but rather' and is used only after a negation ('mitte täna, vaid homme' = not today, but tomorrow). Don't use 'aga' where you need 'vaid'.
Key rule
'But' = aga (spoken/neutral), kuid (neutral/written), ent (literary); all coordinate equals, take a comma before them, and keep SVO after them. Corrective 'but rather' after a negation is 'vaid', not aga.
Examples
- Ma olen väsinud, aga õnnelik.Ma olen väsinud aga õnnelik.
A comma precedes the contrasting 'aga'.
- Ilm oli külm, kuid päike paistis.Ilm oli külm, kuid paistis päike rõhutult ümberpööratuna.
Kuid coordinates equals; the following clause keeps normal SVO order ('päike paistis').
- Ma ei taha teed, vaid kohvi.Ma ei taha teed, aga kohvi.
Corrective 'but rather' after a negation is 'vaid', not 'aga'.
Common mistakes
Using aga instead of vaid for corrective 'but rather'
Ma ei taha teed, aga kohvi.Ma ei taha teed, vaid kohvi.After a negation, the correcting 'but rather' is 'vaid', not aga.
Omitting the comma before aga/kuid
Ma olen väsinud aga õnnelik.Ma olen väsinud, aga õnnelik.A comma precedes the adversative coordinator.
Consequence Connectors: seega, niisiis, järelikult
Järelduse sidesõnad
These words mean 'so / therefore / consequently' — they introduce a RESULT or conclusion that follows from what was just said. 'Seega' = therefore/so, neutral and common: 'Sajab, seega jään koju' = It's raining, so I'm staying home. 'Niisiis' = so/well then, a bit more conversational and conclusive. 'Järelikult' = consequently/it follows, more logical and formal. They link two main clauses with a comma before them: '…, seega …'. Because they begin the result clause (a fronted element), Estonian's V2 rule applies, so the verb comes right after: 'Sajab, seega jään ma koju'. Don't confuse these (result) with sest/kuna (cause): cause answers WHY, result answers SO-WHAT.
Key rule
Consequence = seega / niisiis / järelikult ('so, therefore, consequently'); a comma precedes them and, since they front the result clause, V2 inversion follows ('Sajab, seega jään ma koju'). They mark the RESULT — the cause uses sest/kuna.
Examples
- Sajab, seega jään koju.Sajab seega jään koju.
A comma precedes the result connector 'seega'.
- Buss jäi hiljaks, seega ma hilinesin.Buss jäi hiljaks, sest ma hilinesin.
The second clause is the RESULT, so it needs 'seega', not the cause word 'sest'.
- Sajab, seega jään ma koju.Sajab, seega ma jään koju.
Seega fronts the result clause, so V2 puts the verb before the subject.
Common mistakes
Using a cause connector for a result
Buss jäi hiljaks, sest ma hilinesin.Buss jäi hiljaks, seega ma hilinesin.The second clause states the consequence, which needs seega, not sest.
No inversion after seega (verb third)
Sajab, seega ma jään koju.Sajab, seega jään ma koju. / Sajab, seega jään koju.Seega fronts the result clause, so V2 puts the verb in second position.
Prepositions & Their Government (enne, pärast, ilma, üle, läbi, keset)
Eessõnad ja nende rektsioon
Most Estonian adpositions FOLLOW the noun (postpositions) and take the genitive, but a small set come BEFORE the noun like English prepositions — and you must learn which CASE each one governs. The biggest group takes the PARTITIVE: 'enne tundi' (before the lesson), 'pärast lõunat' (after lunch), 'keset linna' (in the middle of the city), 'mööda teed' (along the road), 'vastu seina' (against the wall). A second group takes the GENITIVE: 'üle jõe' (across the river), 'läbi metsa' (through the forest). And 'ilma' ('without') takes the abessive case (-ta): 'ilma rahata' (without money). So the noun after a preposition is NOT in its dictionary form — it carries the case the preposition demands.
Key rule
A minority of Estonian adpositions PRECEDE the noun, each governing a case: PARTITIVE (enne tundi, pärast lõunat, keset linna, vastu seina, mööda teed), GENITIVE (üle jõe, läbi metsa, ümber maja), and ilma + ABESSIVE (ilma rahata).
Examples
- Enne tundi joon kohvi.Enne tund joon kohvi.
'Enne' governs the partitive ('tundi'), not the nominative 'tund'.
- Pärast lõunat läheme jalutama.Pärast lõuna läheme jalutama.
'Pärast' takes the partitive ('lõunat'), not the nominative 'lõuna'.
- Me ujusime üle jõe.Me ujusime üle jõge.
'Üle' governs the genitive ('jõe'), not the partitive 'jõge'.
Common mistakes
Leaving the noun in the nominative after a preposition
enne tundenne tundiPrepositions govern a case; 'enne' requires the partitive (tundi).
Using the partitive after genitive-governing üle/läbi
üle jõge / läbi metsatüle jõe / läbi metsaÜle and läbi govern the genitive, not the partitive.
Large Numbers + Partitive (kakssada eurot)
Suuremad arvud + osastav
Beyond 100, Estonian builds numbers transparently: sada (100), kakssada (200), tuhat (1000), kaks tuhat (2000), miljon (1,000,000). The key grammar rule stays the same as for small numbers: any number bigger than ONE puts the counted noun in the PARTITIVE SINGULAR — and it is the WHOLE number phrase, however long, that does this: 'kakssada eurot' (200 euros), 'tuhat inimest' (1000 people), 'kolm tuhat krooni'. The noun stays SINGULAR, never plural: 'sada raamatut', not '*sada raamatuid'. Only the number 'üks' (1) and round multiples ending in 'üks…' behave like 1 (üks euro), and compound numbers ending in a number above one keep the partitive ('kakskümmend üks' is special — see note). Watch the spelling: small numbers are written as ONE word (kakssada, kakskümmend), big ones with a space (kaks tuhat).
Key rule
Every cardinal greater than 1 governs the PARTITIVE SINGULAR of the counted noun, and so does the whole long number phrase: kakssada eurot, tuhat inimest, kaks tuhat krooni. The noun stays singular; only 'üks' takes the nominative (üks euro).
Examples
- See maksab kakssada eurot.See maksab kakssada eurod.
After a number > 1 the noun is partitive singular ('eurot'), not nominative plural 'eurod'.
- Saalis oli tuhat inimest.Saalis oli tuhat inimesi.
The noun stays SINGULAR partitive ('inimest'), not plural partitive 'inimesi'.
- Ma ostsin sada raamatut.Ma ostsin sada raamatuid.
Number + partitive SINGULAR ('raamatut'); Estonian never pluralises the counted noun after a number.
Common mistakes
Pluralising the counted noun after a number
sada raamatuidsada raamatutA number governs the partitive SINGULAR; the noun never goes plural after it.
Using the nominative after a number > 1
kakssada eurodkakssada eurotAny number above one requires the partitive (eurot).
Ordinal Numbers (esimene, teine, kolmas)
Järgarvud
Ordinals answer 'which one in order?': esimene (1st), teine (2nd), kolmas (3rd), neljas (4th), viies (5th)… From three upward most ordinals end in -s on the genitive stem (kolm → kolmas, neli → neljas, kuus → kuues, seitse → seitsmes), while 'first' and 'second' are special (esimene, teine). Ordinals are ADJECTIVES, so they DECLINE and AGREE with their noun: 'kolmas korrus' (third floor) but 'kolmandal korrusel' (on the third floor) — note the stem 'kolmanda-' in the cases. In writing, an ordinal is shown by a number plus a FULL STOP: 3. korrus = kolmas korrus, 3. korrusel = kolmandal korrusel. That dot is what marks it as an ordinal, so don't forget it.
Key rule
Ordinals are agreeing adjectives: esimene, teine, then cardinal-genitive-stem + -s (kolmas, neljas, viies). They decline (kolmas → kolmanda → kolmandal) and agree with the noun (kolmandal korrusel). Written with digits, an ordinal takes a FULL STOP: 3. = kolmas.
Examples
- Ma elan kolmandal korrusel.Ma elan kolmas korrusel.
The ordinal must agree in the adessive: 'kolmandal' (not the nominative 'kolmas') with 'korrusel'.
- See on minu teine raamat.See on minu kaks raamat.
'Second' is the ordinal 'teine', not the cardinal 'kaks'.
- Ta lõpetas viienda klassi.Ta lõpetas viies klassi.
Genitive agreement: 'viienda klassi' (the ordinal declines to the genitive stem).
Common mistakes
Using a cardinal where an ordinal is needed
kaks raamat (meaning 'the second book')teine raamat'Second' is the ordinal teine; kaks is the cardinal 'two'.
Not declining the ordinal to agree
kolmas korruselkolmandal korruselThe ordinal agrees in case: adessive kolmandal with korrusel.
Dates — Full Format (kolmas märts; 3. märtsil)
Kuupäevad
An Estonian date uses an ORDINAL number for the day plus the month name (lower-case): 'kolmas märts' = the third of March. To say ON a date — the everyday case — you put BOTH the ordinal and the month into the ADESSIVE (-l): 'kolmandal märtsil' = on the third of March. In writing this is '3. märtsil' (note the ordinal dot). The month is lower-case (jaanuar, veebruar, …, detsember). The year is read as a plain cardinal: 1995 = tuhande üheksasaja üheksakümne viiendal aastal when 'in the year' is meant, or just 'tuhat üheksasada üheksakümmend viis'. Question: 'Mis kuupäev täna on?' (What's the date today?) — answer 'Täna on kolmas märts'. To ask 'on what date?': 'Mis kuupäeval?' → 'kolmandal märtsil'.
Key rule
A date = ordinal day + lower-case month: 'kolmas märts'. ON a date puts BOTH day and month in the adessive: 'kolmandal märtsil' (written 3. märtsil). The day is an ORDINAL (kolmas, not kolm); months are lower-case.
Examples
- Täna on kolmas märts.Täna on kolm märts.
The day is an ORDINAL ('kolmas'), not the cardinal 'kolm'.
- Mu sünnipäev on kolmandal märtsil.Mu sünnipäev on kolmas märts. (when 'on' is meant)
'On' a date requires the ADESSIVE on both words: kolmandal märtsil.
- Eksam on kahekümnendal mail.Eksam on kahekümnes mai.
Both day ordinal and month go into the adessive: kahekümnendal mail.
Common mistakes
Using a cardinal for the day
kolm märtskolmas märtsThe day of the month is an ORDINAL (kolmas), not a cardinal (kolm).
Nominative instead of adessive for 'on a date'
Sünnipäev on kolmas märts. (meaning 'on the 3rd')Sünnipäev on kolmandal märtsil.'On a date' puts both day and month in the adessive (-l).
Telling Time — Advanced (veerand, pool, kümne minuti pärast)
Kellaaeg — laiendus
Beyond full hours, Estonian tells time with veerand (quarter), pool (half) and minute counts. Two things surprise English speakers. First, 'half' looks AHEAD to the next hour: 'pool kolm' = half-WAY to three = 2:30 (not 3:30!). 'Veerand kolm' = quarter toward three = 2:15, and 'kolmveerand kolm' = three-quarters toward three = 2:45. Second, for minutes you use clock phrases like 'kümne minuti pärast kaks' (ten minutes before two = 1:50) and 'kümme minutit kaks läbi' / 'viis minutit üle kahe' (a few minutes past two). In everyday speech people also just say the digits: 'kell on kaks viisteist' (2:15). To ask: 'Mis kell on?' (What time is it?) and 'Mis kell?/Mis kellaks?' (At what time? / By what time?).
Key rule
Estonian half/quarter look FORWARD to the next hour: pool kolm = 2:30, veerand kolm = 2:15, kolmveerand kolm = 2:45. 'In X minutes' = X (genitive) minuti pärast (kümne minuti pärast kaks = 1:50); colloquially you can read the digits (kell on kaks viisteist).
Examples
- Kell on pool kolm.Kell on pool kolm tähenduses 3:30.
'Pool kolm' looks forward = 2:30 (half-way to three), NOT 3:30.
- Kell on veerand neli.Kell on veerand neli tähenduses 4:15.
'Veerand neli' = a quarter into the fourth hour = 3:15, not 4:15.
- Kell on kolmveerand viis.Kell on kolm veerand viis.
'Three quarters to five' is the single word 'kolmveerand' (= 4:45).
Common mistakes
Reading 'pool kolm' as 3:30
Kell on pool kolm = 3:30Kell on pool kolm = 2:30Estonian 'half' looks FORWARD: pool kolm = half-way to three = 2:30.
Reading 'veerand kolm' as 3:15
veerand kolm = 3:15veerand kolm = 2:15Veerand also looks forward: a quarter into the coming hour.
Simple Past (lihtminevik) — Regular Verbs (-sin, -sid, -s)
Lihtminevik — korrapärased verbid
The lihtminevik is Estonian's basic past tense — the equivalent of English 'I lived', 'you worked', 'she studied'. For regular verbs you take the past stem (usually the present stem) and insert the marker -si-, then add the personal endings: -n, -d, nothing, -me, -te, -d. With elama (to live): ma elasin, sa elasid, ta elas, me elasime, te elasite, nad elasid. With töötama (to work): töötasin, töötasid, töötas… The third person singular is the shortest form: just stem + -s (ta elas, ta töötas). As in the present, the ending shows the person, so the pronoun is often dropped (Elasin Tartus = 'I lived in Tartu'). There is no vowel harmony, so the marker is always -si-/-s, never anything else.
Key rule
Lihtminevik (regular): past stem + -si- + ending (-n, -d, -∅, -me, -te, -d). Elama → elasin, elasid, elas, elasime, elasite, elasid. The 3sg is bare stem + -s (ta elas); there is no vowel harmony.
Examples
- Ma elasin Tartus.Ma elan Tartus eile.
Past 'elasin' (with -si-) is needed for past time; 'elan' is present.
- Sa töötasid pangas.Sa töötas pangas.
2sg is -sid (töötasid); -s alone is the 3rd person singular.
- Ta mängis jalgpalli.Ta mängisin jalgpalli.
3sg is bare stem + -s (mängis); -sin is the 1st person.
Common mistakes
Using the present tense for past actions
Eile ma elan Tartus.Eile ma elasin Tartus.A past-time adverb (eile) requires the lihtminevik; insert the -si- marker.
Forgetting the -si- past marker
Ma elan eile (intended past)Ma elasin eile.The simple past is built with -si- between stem and ending: ela-si-n.
Simple Past — Stem Changes & Gradation (lugesin, jõin)
Lihtminevik — tüvemuutused
Many common verbs do not keep the same stem in the past. Three things can happen. (1) Consonant gradation: lugema → ma lugesin (the present stem loe- is replaced by the strong past stem luge-), hakkama → ma hakkasin. (2) Contraction in short verbs: tulema → ma tulin, panema → ma panin, tegema → ma tegin. (3) Stems ending in a long vowel that fuse with the past marker: jooma → ma jõin (I drank), sööma → ma sõin (I ate), saama → ma sain (I got). These are very frequent verbs, so it pays to learn their past forms as small paradigms rather than by rule. The personal endings are the same as for regular verbs (-n, -d, -∅, -me, -te, -d); only the stem differs.
Key rule
Frequent verbs change their stem in the past: gradation (lugema → lugesin), contracted -i past (tulema → tulin, tegema → tegin), and long-vowel fusion (jooma → jõin, sööma → sõin, saama → sain). The endings stay -n/-d/-∅/-me/-te/-d; minema → läksin.
Examples
- Ma lugesin raamatut.Ma loesin raamatut.
The past stem is luge- (g restored), giving lugesin, not the present stem loe-.
- Ta jõi kohvi.Ta joois kohvi.
jooma fuses to jõi (oo → õ + i); there is no -s and no double o.
- Ma sõin leiba.Ma söösin leiba.
sööma → sõin (öö → õ + i); the past is not built with -si-.
Common mistakes
Using the present stem in the past
Ma loesin raamatutMa lugesin raamatutlugema restores the g in the past stem (luge-): ma lugesin, not the present stem loe-.
Adding -si- to long-vowel verbs
Ta joosis / söösisTa jõi / sõijooma/sööma fuse the stem vowel with -i (jõi, sõi); they do not take the -si- marker.
Simple Past of olema (olin, olid, oli)
Olema lihtminevik
The past of olema (to be) is one of the first things to memorise: ma olin, sa olid, ta oli, me olime, te olite, nad olid (I was, you were, he/she was, we were, you were, they were). Just like the present, the third person plural is NOT a special form — 'nad olid' simply matches the rest of the pattern. The past of olema does everything its present does, but in the past: identity (Ma olin õpilane = 'I was a student'), location (Me olime kodus = 'We were at home'), existence (Laual oli raamat = 'There was a book on the table') and possession (Mul oli auto = 'I had a car'). It is also the auxiliary for the compound past tenses you will meet next (olin teinud = 'I had done'), so these six forms are essential.
Key rule
Past of olema: olin, olid, oli, olime, olite, olid. No -si- (it is the contracted -i past). The 3sg is 'oli', the 3pl 'olid'; the past-negative is 'ei olnud' (polnud), never '*ei olin'.
Examples
- Ma olin eile haige.Ma olesin eile haige.
olema has the contracted -i past (olin); there is no -si- form '*olesin'.
- Ta oli õpetaja.Ta olin õpetaja.
3sg is 'oli'; 'olin' is the 1st person.
- Me olime kodus.Me oli kodus.
1pl is 'olime'; 'oli' is only the 3rd person singular.
Common mistakes
Adding -si- to olema
Ma olesin kodusMa olin kodusolema has the contracted -i past (olin, olid, oli); it never takes the -si- marker.
Using 'oli' for all persons
Ma oli / Me oli kodusMa olin / Me olime kodusEach person has its own form (olin, olid, olime, olite). 'Oli' is only 3rd person singular.
Negation of the Simple Past (ei + -nud)
Lihtmineviku eitus
Past negation in Estonian does NOT use the -si- past form. Instead you use the invariant word 'ei' plus the -nud participle: ma ei elanud, sa ei elanud, ta ei elanud, me ei elanud… The participle (the -nud form) is the SAME for every person, and 'ei' never changes — so the whole negative past has just one verb form for all persons. Examples: ma ei läinud (I did not go), ta ei teadnud (he/she did not know), me ei näinud (we did not see). The -nud participle is the same form you use in the perfect (olen teinud), so it is worth learning per verb. Watch out: it is a very common mistake to keep the -si- form and say '*ma ei elasin' — that is wrong. The rule is simply ei + -nud.
Key rule
Negative past = invariant 'ei' + the -nud participle, one form for all persons: ma/sa/ta/me/te/nad ei elanud. Never use the -si- form after 'ei' (NOT '*ei elasin'). The object becomes partitive (ei lugenud raamatut).
Examples
- Ma ei elanud Tartus.Ma ei elasin Tartus.
Past negation uses ei + -nud (ei elanud); the -si- form is never used after 'ei'.
- Ta ei läinud kooli.Ta ei läks kooli.
The negative past of minema is 'ei läinud' (-nud participle), not the affirmative 'läks'.
- Me ei näinud filmi.Me ei nägime filmi.
Negation requires the -nud participle (näinud); '*nägime' is the affirmative past.
Common mistakes
Keeping the -si- past after 'ei'
Ma ei elasin siinMa ei elanud siinAfter 'ei' Estonian uses the bare -nud participle, never the affirmative -si- form.
Keeping the affirmative 3sg after 'ei'
Ta ei läks kojuTa ei läinud kojuNegative past is ei + -nud; 'läks' is the affirmative past of minema.
Present Perfect (täisminevik) — Formation (olen teinud)
Täisminevik — moodustamine
The täisminevik (present perfect) is Estonian's 'have done' tense. It is a compound tense made of two parts: the present tense of olema + the -nud participle. So 'I have done' = ma olen teinud, 'you have seen' = sa oled näinud, 'he has been' = ta on olnud, 'we have read' = me oleme lugenud, 'they have come' = nad on tulnud. Only the olema part changes for person (olen, oled, on, oleme, olete, on); the -nud participle stays exactly the same. The participle is the same -nud form you use in negative past sentences (ei teinud), so once you know it, you can build both. The negative is 'ei ole … -nud' (ma ei ole teinud / ma pole teinud). This tense is built the same way in English and Estonian, which makes it easier than it looks.
Key rule
Täisminevik = present of olema + the invariant -nud participle: olen teinud, oled teinud, on teinud, oleme teinud, olete teinud, on teinud. Only olema changes for person; negation is 'ei ole / pole … -nud'.
Examples
- Ma olen Eestis käinud.Ma olen Eestis käima.
The perfect needs the -nud participle (käinud), not the infinitive 'käima'.
- Sa oled selle raamatu lugenud.Sa olen selle raamatu lugenud.
The auxiliary must match the subject: 'sa oled', not 'sa olen'.
- Ta on filmi näinud.Ta on filmi nägenud.
nägema → näinud (irregular -nud form); '*nägenud' is wrong.
Common mistakes
Using the infinitive instead of the participle
Ma olen käima EestisMa olen Eestis käinudThe perfect is olema + -nud participle (käinud), never olema + -ma infinitive.
Wrong auxiliary person
Sa olen lugenud raamatuSa oled selle raamatu lugenudThe auxiliary olema must agree with the subject (sa oled).
Present Perfect — Usage (experience, result-now)
Täismineviku kasutus
Knowing how to BUILD the täisminevik is one thing; knowing WHEN to use it is another. Estonian uses the present perfect (olen teinud) much like English 'have done': (1) for life experience without a definite time — Ma olen Eestis käinud ('I have been to Estonia [at some point]'); (2) for a past action whose result matters now — Ta on ära läinud ('He has left' = he is gone now). When you give a specific past time (eile, kell viis, 2010), Estonian normally switches to the simple past (lihtminevik): Ma käisin Eestis 2010. So the contrast is: täisminevik = experience / present relevance, no fixed time; lihtminevik = a specific completed event in the past. This is similar to English, but Estonian uses the simple past a bit more freely, so when in doubt and a time is given, use the lihtminevik.
Key rule
Täisminevik = experience (no fixed time: Olen Eestis käinud) or a result that matters now (Ta on ära läinud). Lihtminevik = a specific past time / narrative event (Käisin Eestis 2010). A definite time adverbial usually selects the simple past.
Examples
- Ma olen Eestis käinud.Ma olen Eestis käinud 2010.
With a specific year use the simple past: Ma käisin Eestis 2010. The perfect is for unspecified experience.
- Ma käisin eile kinos.Ma olen eile kinos käinud.
A definite time (eile) selects the lihtminevik (käisin), not the perfect.
- Ta on ära läinud.Ta läks ära (kui sa tahad öelda, et ta on praegu ära).
For a result that holds now ('he is gone'), the perfect 'on ära läinud' is natural.
Common mistakes
Using the perfect with a specific past time
Ma olen eile käinud kinosMa käisin eile kinosA definite time adverbial (eile) requires the simple past, not the perfect.
Using the simple past for life experience
Sõid sa kunagi eesti toitu? (intended 'ever')Oled sa kunagi eesti toitu söönud?An 'ever in your life' question uses the perfect with kunagi.
Imperative — 2nd Person Singular (Tule! Ära mine!)
Käskiv kõneviis — ainsuse 2. pööre
To tell ONE person (informally) to do something, Estonian uses the bare imperative — it is simply the present stem with no ending: Tule! ('Come!'), Söö! ('Eat!'), Loe! ('Read!'), Vaata! ('Look!'), Oota! ('Wait!'). For most verbs this equals the verb without its -ma/-da, e.g. tulema → Tule!, lugema → Loe!, ootama → Oota!. To tell someone NOT to do something you use the special negative word 'ära' + the same bare form: Ära tule! ('Don't come!'), Ära söö! ('Don't eat!'), Ära mine! ('Don't go!'). Note that the negative imperative does NOT use the ordinary 'ei' — it uses 'ära' for one person. So: positive = bare stem (Tule!); negative = ära + bare stem (Ära tule!).
Key rule
2sg imperative = the bare present stem (Tule! Loe! Mine!). Negative = the special word 'ära' + the bare stem (Ära tule! Ära mine!) — NOT 'ei'. An affirmative total object is nominative (Ava uks!).
Examples
- Tule siia!Tuled siia!
The imperative is the bare stem (tule); '-d' is the present 2sg ending, not a command.
- Loe see lause ette!Loed see lause ette!
lugema → imperative 'loe' (bare stem), not the present 'loed'.
- Ära mine veel!Ei mine veel!
The negative singular imperative uses 'ära', not the ordinary 'ei'.
Common mistakes
Using the present 2sg as a command
Tuled siia!Tule siia!The imperative is the bare stem (tule); the '-d' ending makes it a statement/question.
Using 'ei' instead of 'ära' for a negative command
Ei tule praegu!Ära tule praegu!The singular negative imperative uses the dedicated negator 'ära', not 'ei'.
Imperative — Plural / Formal (Tulge! Ärge minge!)
Käskiv kõneviis — mitmus ja viisakas vorm
To command MORE THAN ONE person, or to address one person politely (with 'teie'), Estonian adds -ge or -ke to the verb stem: Tulge! ('Come!' to several / formally), Sööge! ('Eat!'), Lugege! ('Read!'), Oodake! ('Wait!'), Vaadake! ('Look!'). The ending is -ge after a voiced sound and -ke after a voiceless consonant: tule → tulge, oota → ooda + ke = oodake, võt → võtke. This is the same form you use to be polite to a stranger: Vabandage! ('Excuse me!'), Andke andeks! ('Forgive me!'). The negative uses the word 'ärge' (the plural of 'ära') + the -ge/-ke form: Ärge minge! ('Don't go!'), Ärge muretsege! ('Don't worry!'). So plural/polite positive = stem + -ge/-ke; negative = ärge + -ge/-ke form.
Key rule
Plural/polite imperative = stem + -ge/-ke (Tulge! Oodake! Lugege!), used for several people OR politely for 'teie'. Negative = 'ärge' + the -ge/-ke form (Ärge minge!). -ke after p/t/k/s, -ge otherwise.
Examples
- Lapsed, tulge sööma!Lapsed, tule sööma!
Several addressees need the plural imperative tulge, not the singular tule.
- Vabandage, kus on jaam?Vabanda, kus on jaam? (võõra inimese puhul)
Politely to a stranger use the plural/polite form Vabandage, not the familiar singular.
- Oodake hetk, palun!Ootage hetk, palun!
ootama takes -ke after the voiceless t: oota → oodake (with gradation), not '*ootage'.
Common mistakes
Using the singular imperative for several people / politeness
Tule sisse! (kliendile)Tulge sisse!Address several people or be polite with the -ge/-ke form (tulge).
Wrong ending choice (-ge vs -ke)
Ootage / võtgeOodake / võtke-ke goes after voiceless p/t/k/s (oodake, võtke); -ge elsewhere (tulge, sööge).
Let's… (Lähme! Teeme!) — 1st Person Plural
Üleskutse (lähme, teeme)
To say 'Let's …' — a suggestion that includes yourself — Estonian most often just uses the ordinary present tense 'we' form (the -me ending): Lähme! ('Let's go!'), Teeme! ('Let's do it!'), Sööme! ('Let's eat!'), Vaatame! ('Let's watch!'), Ootame! ('Let's wait!'). It looks identical to the present 'we do' form, but as a stand-alone invitation it means 'let's'. You can add the pronoun for clarity (Lähme me kinno = 'Let's go to the cinema') or leave it out. To suggest NOT doing something, you use the plural negative imperative with 'ärme' (colloquial) or, more formally, 'ärgem': Ärme mine! / Ärgem mingem! ('Let's not go!'). In everyday speech the -me form (Lähme!) and 'ärme …' are by far the most common way to say 'let's' and 'let's not'.
Key rule
'Let's …' = the present 1pl -me form used as an invitation: Lähme! Teeme! Sööme! 'Let's not …' = colloquial 'ärme …' (Ärme mine!) or formal 'ärgem -gem' (Ärgem mingem!). The pronoun 'me' is usually dropped.
Examples
- Lähme kinno!Lähema kinno!
'Let's go' is the 1pl present form lähme (minema → läh- + -me), not an invented '*lähema'.
- Teeme seda koos!Tee seda koos! (kui mõtled 'teeme')
For 'let's do it' (including yourself) use the -me form teeme, not the singular imperative tee.
- Sööme nüüd!Söögem nüüd! (igapäevases kõnes)
Everyday 'let's eat' is sööme; the -gem form (söögem) is formal/literary.
Common mistakes
Using the singular imperative for 'let's'
Mine kinno! (meaning 'let's go')Lähme kinno!'Let's' includes the speaker → the 1pl -me form (lähme), not the singular command (mine).
Inventing a form for the -me hortative
Lähema / teemesLähme / teeme'Let's' is simply the regular present 1pl form: lähme, teeme, sööme.
Pidama (must / should) — Full Use + Conditional peaks
Pidama-verb — täielik kasutus
Pidama means 'must / have to' and expresses obligation. The key thing to remember: pidama takes the MA-INFINITIVE (the dictionary -ma form), not the da-infinitive. So you say 'Ma pean MINEMA' (I must go), not 'Ma pean minna'. Pidama conjugates normally for person: pean, pead, peab, peame, peate, peavad. The verb you must do stays in the ma-form: Ma pean töötama (I must work), Sa pead ootama (you must wait), Ta peab õppima (he/she must study). In the present, pidama also expresses logical assumption ('must be'): Ta peab kodus olema (he must be home). The CONDITIONAL peaks(in) softens it to English 'should': Sa peaksid puhkama (you should rest), Ma peaksin helistama (I should call). Negation is invariant: Ma ei pea minema (I don't have to go).
Key rule
Pidama = must / have to, conjugates normally with a NOMINATIVE subject, and takes the MA-INFINITIVE: Ma pean minema. Conditional peaksin/peaksid/peaks = 'should'. Negation is invariant: Ma ei pea minema.
Examples
- Ma pean homme vara tõusma.Ma pean homme vara tõusta.
Pidama takes the ma-infinitive (tõusma), never the da-infinitive (tõusta).
- Sa pead seda raamatut lugema.Sa pean seda raamatut lugema.
Pidama conjugates for person: 2sg = pead, not pean.
- Ta peab kohe minema.Ta peab kohe minna.
The complement of pidama is the ma-form minema, not minna.
Common mistakes
Using the da-infinitive after pidama
Ma pean minna koju.Ma pean koju minema.Pidama governs the MA-infinitive (minema), not the da-infinitive (minna).
Not conjugating pidama for person
Sa pean ootama.Sa pead ootama.Unlike Finnish, Estonian pidama conjugates normally: pean/pead/peab/peame/peate/peavad.
Choosing ma- vs da-infinitive after Verbs
Ma- ja da-infinitiivi valik
Estonian has two infinitives — the ma-infinitive (minema, tegema, sööma) and the da-infinitive (minna, teha, süüa) — and which one you use depends on the governing verb, not on you. There is no single rule, but there are reliable lists. Verbs of STARTING, GOING-TO-DO and necessity take the MA-infinitive: hakkan tegema (I start doing), pean minema (I must go), lähen ostma (I go to buy). Verbs of WANTING, ABILITY, LIKING and most others take the DA-infinitive: tahan teha (I want to do), oskan ujuda (I can swim), saan tulla (I can come), armastan lugeda (I love to read), püüan aidata (I try to help). The safest strategy is to learn the governing verb together with the infinitive form it requires, the way you learn a verb with its case.
Key rule
The governing verb decides the infinitive. Starting/necessity/purpose-motion → MA-infinitive (hakkan tegema, pean minema, lähen ostma); wanting/ability/liking/trying → DA-infinitive (tahan teha, oskan ujuda, meeldib lugeda).
Examples
- Ma hakkan eesti keelt õppima.Ma hakkan eesti keelt õppida.
Hakkama (to start) governs the ma-infinitive: õppima, not õppida.
- Ma tahan eesti keelt õppida.Ma tahan eesti keelt õppima.
Tahtma (to want) governs the da-infinitive: õppida, not õppima.
- Ta oskab hästi ujuda.Ta oskab hästi ujuma.
Oskama (to be able / know how) takes the da-infinitive: ujuda.
Common mistakes
ma-infinitive after tahtma
Ma tahan minema.Ma tahan minna.Tahtma governs the da-infinitive: tahan minna.
da-infinitive after hakkama
Ma hakkan teha.Ma hakkan tegema.Hakkama governs the ma-infinitive: hakkan tegema.
Hakkama (to start / be going to) + ma-infinitive
Hakkama-verb
Hakkama means 'to start / begin' and is also Estonian's everyday way of saying 'be going to' for the near future. It always takes the MA-infinitive: Ma hakkan õppima (I'm starting to study / I'm going to study), Ta hakkab tööle (he's starting work). Conjugation: hakkan, hakkad, hakkab, hakkame, hakkate, hakkavad; past hakkasin (I started). Because Estonian has no separate future tense, hakkama + ma-infinitive often does the job of English 'will / be going to': Ma hakkan kohe minema (I'm about to leave / I'll leave now). Watch the stem change: the present is hakka-, but the da-infinitive is hakata and the past is hakkasin (consonant gradation kk/k). Negation: Ma ei hakka ootama (I won't start waiting).
Key rule
Hakkama = start / be going to, and ALWAYS takes the ma-infinitive: Ma hakkan tegema. Mind the gradation: present hakka-, da-infinitive hakata, past hakkasin. Negation: Ma ei hakka tegema.
Examples
- Ma hakkan eesti keelt õppima.Ma hakkan eesti keelt õppida.
Hakkama governs the ma-infinitive õppima, never the da-infinitive õppida.
- Varsti hakkab sadama.Varsti hakkab sadada.
Hakkama + ma-infinitive sadama; 'it's going to rain'.
- Me hakkame kohe minema.Me hakkame kohe minna.
The complement is the ma-form minema; minna would follow tahtma, not hakkama.
Common mistakes
Using the da-infinitive after hakkama
Ma hakkan teha.Ma hakkan tegema.Hakkama always governs the ma-infinitive: tegema.
Not applying gradation in the past/da-infinitive
Ma hakkasin õppida.Ma hakkasin õppima.Hakkama governs the ma-infinitive (õppima), not the da-infinitive (õppida); note too that hakkama itself gradates kk/k — present strong hakka-, weak-grade da-infinitive hakata, past hakkasin.
Motion Verbs + Locative Cases (lähen kooli, tulen koju)
Liikumisverbid kohakäänetega
Motion verbs in Estonian decide the case of the place word. Verbs of going TO a place take a 'where-to' case (illative -sse or the short form, or allative -le for surfaces/people): lähen kooli (I go to school), lähen lauale (onto the table), lähen sõbra juurde (to a friend). Verbs of coming/going FROM take a 'from' case (elative -st, ablative -lt): tulen koolist (I come from school), tulen laualt (from the table). Being AT a place takes a 'where' case (inessive -s, adessive -l): olen koolis (I'm at school). Two very common irregular short forms: koju (home, direction) vs kodus (at home), and tuppa (into the room) vs toas (in the room). So: lähen koju, olen kodus, tulen koju, but *lähen kodusse is wrong.
Key rule
Match the case to the motion: going TO → where-to (kooli, lauale, koju); being AT → where (koolis, laual, kodus); coming FROM → where-from (koolist, laualt, kodust). Irregular pairs: koju/kodus, tuppa/toas.
Examples
- Ma lähen kooli.Ma lähen koolis.
Minema is directional → where-to (kooli, short illative); koolis is 'at school'.
- Ma olen koolis.Ma olen kooli.
Olema = location → where (koolis); kooli would be the direction.
- Ma tulen koolist.Ma tulen kooli.
'Come from' → where-from (elative koolist); kooli is 'to school'.
Common mistakes
Location case after a motion verb
Ma lähen koolis.Ma lähen kooli.Minema needs a where-to case; koolis means 'at school' (location).
Direction case after olema
Ma olen koju.Ma olen kodus.Olema marks location → where (kodus); koju is the direction.
The mas-form (olen tegemas) — "in the act of"
Mas-vorm
The mas-form is the ma-infinitive with the inessive ending -s (tege-mas, uju-mas, söö-mas). It means being IN THE MIDDLE OF / AT an activity, usually with a verb of position or motion. Two main patterns: (1) with olema, ongoing action — Ma olen söömas (I'm eating / I'm at a meal), Ta on ujumas (he's swimming). (2) with käima 'go (and come back)', a regular activity — Ma käin ujumas (I go swimming), Ma käin tööl ja õhtul jõusaalis trennis. (3) with minema 'go to do' — Ma lähen ujumas? No — direction uses the plain ma-form ujuma; the mas-form answers KUS? (where), so it pairs with käima/olema. So: lähen ujuma (go to swim, direction) but käin ujumas (go swimming, location/activity). The mas-form is built from the ma-infinitive, so the same stem: õppi-mas, tege-mas, jooks-mas.
Key rule
The mas-form = ma-infinitive + inessive -s (tegemas, ujumas), used with olema (ongoing: olen söömas) and käima (regular: käin ujumas) to mean 'at / in the act of' an activity. It answers KUS?, not KUHU?.
Examples
- Ma olen praegu söömas.Ma olen praegu sööma.
Ongoing activity with olema takes the mas-form (söömas), not the bare ma-form.
- Ma käin igal teisipäeval ujumas.Ma käin igal teisipäeval ujuma.
Käima 'attend/go-and-return' takes the mas-form ujumas (KUS?), not ujuma.
- Ema on aias töötamas.Ema on aias töötama.
Being away at an activity with olema → töötamas.
Common mistakes
Bare ma-form with käima/olema for an activity
Ma käin ujuma.Ma käin ujumas.Käima/olema + activity require the mas-form (KUS?): käin ujumas.
mas-form after minema (direction)
Ma lähen ujumas.Ma lähen ujuma.Minema marks direction (KUHU?) and takes the bare ma-form ujuma, not the inessive mas-form.
The mast-form (tulen tegemast) — "from doing"
Mast-vorm
The mast-form is the ma-infinitive with the elative ending -st (tege-mast, uju-mast, söö-mast). It means coming/returning FROM an activity, and answers KUST? (from where). It is the natural partner of the mas-form: olen ujumas (I'm swimming, at it) → tulen ujumast (I come back from swimming). Main use: with tulema/saabuma — Ma tulen just ujumast (I've just come from swimming), Ta tuli koosolekult? No — koosolekult is a place; from an ACTIVITY verb you use the mast-form: tulen söömast, tulen poest? No, poest is a place too. The mast-form is specifically for the ACTIVITY: tulen trennist treenimast / tulen ujumast. It also follows some verbs of stopping/preventing: Ma loobusin suitsetamast (I gave up smoking), Ta hoidus kommenteerimast (he refrained from commenting).
Key rule
The mast-form = ma-infinitive + elative -st (tegemast, ujumast), meaning 'from doing'. Use it with tulema (tulen ujumast = come from swimming) and after ceasing/preventing verbs (loobusin suitsetamast). It answers KUST?.
Examples
- Ma tulen just ujumast.Ma tulen just ujumas.
Returning FROM an activity uses the mast-form ujumast (KUST?); ujumas is being AT it.
- Lapsed tulid õuest mängimast.Lapsed tulid õuest mängima.
'Came from playing' → mast-form mängimast, not the directional bare ma-form.
- Ma loobusin suitsetamast.Ma loobusin suitsetama.
Loobuma (give up) governs the mast-form: loobusin suitsetamast.
Common mistakes
mas-form where mast is needed
Ma tulen ujumas.Ma tulen ujumast.Tulema = movement from → mast-form (KUST?); mas is being at the activity.
Bare ma-form after loobuma/hoiduma
Ma loobusin suitsetama.Ma loobusin suitsetamast.Ceasing/refraining verbs govern the elative mast-form.
Reflexive Verbs / ennast (pesema end, tundma end)
Enesekohased verbid — ennast
When the action turns back on the doer ('myself, yourself'), Estonian uses the reflexive object ennast (longer) or end (shorter) — they mean the same thing. Ma pesen ennast (I wash myself), Ta tunneb end hästi (he feels well — lit. feels himself well), Vaata ennast peeglist (look at yourself in the mirror). The form ennast/end is the same for all persons in everyday A2 use, though there are personal forms (iseennast etc.) you'll meet later. Many common Estonian verbs are inherently reflexive without a separate object, ending in -uma/-ima: pesema 'wash (sth)' vs the reflexive sense often just adds ennast; riietuma 'get dressed', istuma 'sit down', tundma end 'feel'. Key contrast: Ma pesen autot (I wash the car — object) vs Ma pesen ennast (I wash myself — reflexive).
Key rule
Reflexive object = ennast or end (interchangeable): Ma pesen ennast, Ta tunneb end hästi. Many everyday verbs are inherently reflexive in -uma (riietun = I get dressed) and need NO object. Contrast: pesen autot (sth) vs pesen ennast (myself).
Examples
- Ma pesen ennast.Ma pesen mind.
The reflexive object is ennast/end, not the personal pronoun mind.
- Ta tunneb end täna hästi.Ta tunneb teda täna hästi.
'Feel (a way)' is tundma + end (self); teda would mean 'feels him' (someone else).
- Vaata ennast peeglist!Vaata sind peeglist!
Reflexive ennast, not the pronoun sind.
Common mistakes
Personal pronoun instead of the reflexive
Ma pesen mind.Ma pesen ennast.When subject = object, use the reflexive ennast/end, not mind/sind/teda.
Reflexive object with an -uma middle verb
Ma riietan ennast. (for 'I get dressed')Ma riietun.Riietuma already encodes the reflexive; riietama + object means dressing someone else.
olema + Adessive/Inessive for States (olen tööl, olen kodus)
Olema + kohakääne — seisund
Estonian uses olema (to be) plus a place-case to say where you ARE and, idiomatically, what STATE you are in. Many of these are fixed and you must learn the right case. The 'on/at' series (adessive -l) covers a lot of activity-states: olen tööl (I'm at work), olen koolis? — no, kool is inside (koolis), but olen tööl, puhkusel (on holiday), reisil (travelling), pulmas? (pulmas, inside-event). The 'in' series (inessive -s) covers being inside/at an event or condition: olen kodus (at home), haiglas (in hospital), koosolekul? (adessive — at a meeting), olen heas tujus (in a good mood), olen hädas (in trouble). The case is often unpredictable, so learn these as phrases: tööl, kodus, koolis, puhkusel, haige (just adjective!), väsinud. Note 'I'm sick' is simply Ma olen haige (adjective, no case), but 'I'm at work' is Ma olen tööl (adessive).
Key rule
olema + a fixed locative case expresses states: olen tööl (adessive), olen kodus (inessive), olen heas tujus. Learn the case per phrase. Adjective-states take NO case: olen haige, väsinud, valmis.
Examples
- Ma olen praegu tööl.Ma olen praegu töös.
'At work' is the adessive tööl; töös means 'in progress / being worked on'.
- Ma olen õhtul kodus.Ma olen õhtul koju.
State/location = kodus (inessive); koju is the direction (homeward).
- Ema on sel nädalal puhkusel.Ema on sel nädalal puhkuses.
'On holiday/leave' is fixed as the adessive puhkusel, not inessive.
Common mistakes
Direction case for a state
Ma olen koju.Ma olen kodus.A state/location with olema takes kodus (inessive); koju is the direction.
Wrong series (inessive vs adessive)
Ma olen töös.Ma olen tööl.'At work' is the adessive tööl; töös means 'in progress'.
