učiti / naučiti (to learn / study) | Croatian Grammar

Učiti ("to learn / study") packs two English verbs into one and adds an aspect twist on top. The imperfective učiti covers both "to study" (put in the work) and "to learn" (the process of acquiring); its perfective partner naučiti zeroes in on the result — "to learn [for good], master". The aspect contrast here is unusually meaningful for learners, because it maps onto the difference between trying to learn and succeeding: učio sam "I studied (maybe it didn't stick)" versus naučio sam "I learned it (it stuck)".

Aspect

	Imperfective	Perfective
Verb	učiti	naučiti
Core sense	study, be learning (effort, process)	learn [and retain], master (result)
Typical use	Učim hrvatski. "I'm studying Croatian."	Naučio sam pjesmu. "I've learned the poem."
Implies	activity, not necessarily success	success — it's now known

This is the crucial nuance: učiti za ispit ("to study for an exam") describes the work; naučiti gradivo ("to learn the material") describes mastering it. You can učiti something for hours and still not naučiti it. English blurs this with "study" vs "learn", but neither English verb forces the completion the way naučiti does. The general aspect logic is on aspect overview.

💡

Think of učiti as the camera rolling on you at your desk, and naučiti as the moment the knowledge clicks into place. Učio sam, ali nisam naučio — "I studied, but I didn't learn it" — is a perfectly sensible (and very relatable) Croatian sentence.

Present tense (i-class)

Učiti is a regular i-class verb: stem uč-, endings -im, -iš, -i, -imo, -ite, -e. The 3rd-person plural is the bare -e (uče), not -aju.

Person	učiti (impf)	naučiti (pf — future/subordinate sense)
ja	učim	naučim
ti	učiš	naučiš
on/ona/ono	uči	nauči
mi	učimo	naučimo
vi	učite	naučite
oni/one/ona	uče	nauče

Učim hrvatski već dvije godine.

I've been studying Croatian for two years already.

Što učiš za sutra?

What are you studying for tomorrow?

Kad naučim ovih dvadeset riječi, idem van.

Once I've learned these twenty words, I'm going out. — perfective present 'naučim' has future sense after 'kad'.

The l-participle

Regular for an -iti verb: stem uči- + endings. Masculine učio shows the vocalised -l.

Gender / number	učiti	naučiti
masculine singular	učio	naučio
feminine singular	učila	naučila
neuter singular	učilo	naučilo
masculine plural	učili	naučili
feminine plural	učile	naučile
neuter plural	učila	naučila

Perfect tense (perfekt)

The clearest place to feel the aspect: učila sam "I was studying / used to study"; naučila sam "I learned / mastered it". Clitic biti + l-participle.

Person	učiti (masc.)	naučiti (masc.)
ja	učio sam	naučio sam
ti	učio si	naučio si
on / ona	učio / učila je	naučio / naučila je
mi	učili smo	naučili smo
vi	učili ste	naučili ste
oni / one	učili su	naučili su

Učio sam cijelu noć, ali sam svejedno pao na ispitu.

I studied all night, but I still failed the exam. — imperfective: effort, no guaranteed result.

Napokon sam naučila voziti bicikl s pet godina.

I finally learned to ride a bike at the age of five. — perfective: a mastered skill, feminine speaker.

Future I (futur prvi)

Učiti drops its -i before the clitic: učit ću; likewise naučit ću.

Person	učiti	naučiti
ja	učit ću	naučit ću
ti	učit ćeš	naučit ćeš
on/ona/ono	učit će	naučit će
mi	učit ćemo	naučit ćemo
vi	učit ćete	naučit ćete
oni/one/ona	učit će	naučit će

Cijeli vikend ću učiti za prijemni.

I'll be studying for the entrance exam all weekend. — imperfective future: the ongoing effort.

Imperative

i-class imperatives end in -i, -imo, -ite. The perfective nauči! says "learn it (master it)"; the imperfective uči! says "study / keep studying".

Person	učiti	naučiti
ti	uči	nauči
mi	učimo	naučimo
vi	učite	naučite

Nauči ovo napamet do petka.

Learn this by heart by Friday. — perfective: get it mastered.

Uči redovito, ne sve zadnju noć.

Study regularly, not all on the last night. — imperfective: habitual activity.

Conditional I (kondicional prvi)

bih-clitics + l-participle.

Person	učiti (masc.)	naučiti (masc.)
ja	učio bih	naučio bih
ti	učio bi	naučio bi
on/ona/ono	učio bi	naučio bi
mi	učili bismo	naučili bismo
vi	učili biste	naučili biste
oni/one/ona	učili bi	naučili bi

Brže bih naučio da imam dobrog učitelja.

I'd learn faster if I had a good teacher.

Other forms

Passive participle: učen, učena, učeno ("learned, taught") and perfective naučen, naučena, naučeno ("learned [by heart]"). As an adjective učen means "learned, erudite": učen čovjek "a learned man". Naučena lekcija "a lesson learned".
Present verbal adverb (učiti only): učeći ("[while] studying"). Perfectives form a past verbal adverb instead: naučivši ("having learned"), literary.
Reflexive učiti se: with the dative of a thing, "to study / learn (a skill)" — učiti se strpljenju "to learn patience". More common today is the plain transitive.

On je vrlo učen, doktorirao je u Beču.

He's very learned, he did his doctorate in Vienna. — 'učen' as an adjective.

Učeći jezik, najviše naučiš slušajući.

When learning a language, you learn the most by listening. — verbal adverb 'učeći'.

Government

1. učiti + accusative — "to study a subject"

The thing studied takes the accusative: učiti matematiku, povijest, hrvatski. See the accusative direct object.

Sestra mi uči medicinu, a ja pravo.

My sister is studying medicine, and I'm studying law. — accusative objects.

2. učiti / naučiti + infinitive (or da-clause) — "to learn to do"

To say "learn to [do something]", naučiti takes an infinitive: naučiti plivati "to learn to swim". In many contexts a da-clause is an everyday alternative — naučiti da plivam; the choice is treated on da vs the infinitive.

Naučila sam kuhati od bake.

I learned to cook from my grandmother. — 'naučiti' + infinitive 'kuhati'.

Moraš naučiti reći ne.

You have to learn to say no. — 'naučiti' + infinitive 'reći'.

3. učiti also = "to teach"

A trap for English speakers: in informal and standard usage učiti can mean "to teach", with the learner in the accusative and the subject taught in the dative or accusative: Učim ga matematiku "I'm teaching him maths". For "teach" in a school setting, the unambiguous verbs are predavati ("to lecture, teach a subject", impf) and poučavati ("to instruct"). When you mean "study/learn", staying with učiti + the subject in the accusative keeps you clear.

Baka me učila plesti dok sam bila mala.

Grandma taught me to knit when I was little. — 'učiti' = teach: accusative learner 'me' + infinitive.

For "to study at university", Croatian uses studirati: studiram na faksu "I study at uni". Učiti is the day-to-day "study/cram"; studirati is "to be a student of / pursue a degree in".

Studiram informatiku, ali večeras moram učiti statistiku.

I study computer science, but tonight I have to study statistics. — 'studirati' (be enrolled) vs 'učiti' (cram).

Common Mistakes

❌ Oni učiju za ispit.

Incorrect — the i-class 3pl is the bare -e: 'uče', not '*učiju'.

✅ Oni uče za ispit.

They're studying for the exam.

❌ Naučio sam cijeli dan, ali ne znam ništa.

Aspect clash — studying all day (effort, no result) is imperfective 'učio sam'.

✅ Učio sam cijeli dan, ali ne znam ništa.

I studied all day, but I don't know anything.

❌ Studiram za ispit večeras.

False friend — 'studirati' = be enrolled at university; for 'cram for an exam' use 'učiti'.

✅ Učim za ispit večeras.

I'm studying for the exam tonight.

❌ Naučio sam plivanje.

Awkward — 'learn to do' takes the infinitive: 'naučiti plivati', not the noun.

✅ Naučio sam plivati.

I learned to swim.

❌ Učim u sveučilištu.

Wrong verb for 'study at university'; use 'studirati': 'studiram na fakultetu'.

✅ Studiram na fakultetu.

I study at university.

Key Takeaways

Učiti (impf, "study / be learning") vs naučiti (pf, "learn / master") — the perfective adds the result: učio sam (tried) vs naučio sam (succeeded).
Regular i-class: učim, učiš, uči, učimo, učite, uče — bare -e in the 3pl.
Government: accusative subject (učim hrvatski); infinitive for "learn to" (naučiti plivati).
Učiti can also mean "to teach" (learner in accusative); for university enrolment use studirati, for classroom teaching predavati / poučavati.
Passive/adjective učen ("learned"); future učit ću.
