English gets by with three verbs — "study," "learn," "teach" — and lets context sort out the rest. Russian splits the same territory across four verbs whose difference is not vocabulary but government and meaning: each one demands a particular case after it, and each one frames the activity differently (memorizing, attending, researching, practising). Choosing wrongly is not a small slip — saying учи́ть фи́зику instead of изуча́ть фи́зику, or занима́ться ру́сский instead of занима́ться ру́сским, instantly marks a sentence as non-native. The good news: once you tie each verb to its case and its core idea, the choice becomes mechanical. This page gives you that decision procedure.
The decision in one table
Run the situation through this lookup. The case the verb governs is half of getting it right.
| You mean… | Verb | Government | Example |
|---|---|---|---|
| commit to memory | учи́ть |
| учи́ть слова́ |
| teach (impart to someone) | учи́ть |
| учи́ть дете́й матема́тике |
| be a student / learn how to | учи́ться | where (в/на) or + infinitive | учи́ться в университе́те; учи́ться пла́вать |
| study a subject in depth | изуча́ть |
| изуча́ть фи́зику |
| work on / practise / engage in | занима́ться | занима́ться ру́сским, спо́ртом |
Учи́ть: memorize — or teach
This is the trickiest of the four because it does two opposite jobs depending on what cases surround it.
Учи́ть + accusative of a thing = memorize, learn by heart. Here you are loading something into your head: words, a poem, the rules, a role. The action is the act of committing to memory, not understanding deeply.
Мне ещё на́до вы́учить э́ти слова́ к за́втрашнему уро́ку.
I still need to learn these words by heart for tomorrow's lesson. — учи́ть/вы́учить + accusative слова́ = memorize.
Он це́лый ве́чер учи́л стихотворе́ние наизу́сть.
He spent the whole evening learning the poem by heart. — учи́ть + accusative = memorize.
Учи́ть + accusative person + dative subject = teach. The same verb flips to "teach" when there is a person in the accusative (the learner) and a subject in the dative (what you teach them). The dative on the subject is the part English speakers forget — there is no preposition, just a bare dative.
Ба́бушка у́чит вну́чку пе́нию.
Grandma teaches her granddaughter singing. — учи́ть + accusative person (вну́чку) + dative subject (пе́нию).
Кто учи́л тебя́ води́ть маши́ну?
Who taught you to drive? — учи́ть + accusative тебя́ + infinitive води́ть (teaching a skill can take an infinitive instead of a dative noun).
Учи́ться: be a student, learn how to do something
Add the reflexive -ся and the focus turns back on the learner. Учи́ться means "to study" in the sense of being a student / being enrolled, or "to learn how to" do something (with an infinitive). It does not take a direct object — you cannot учи́ться something; you study somewhere or learn to do something.
Моя́ сестра́ у́чится в медици́нском университе́те на тре́тьем ку́рсе.
My sister is studying at medical university, in her third year. — учи́ться + location: being a student there.
В де́тстве я до́лго учи́лся ката́ться на велосипе́де.
As a kid it took me ages to learn to ride a bike. — учи́ться + infinitive ката́ться: learning how to.
Учи́ться никогда́ не по́здно.
It's never too late to learn / to study. — учи́ться used absolutely, no object.
Изуча́ть: study a subject seriously, in depth
Изуча́ть + accusative is the academic verb: to study a field, subject, or phenomenon thoroughly — what a scholar, researcher, or serious student does. It implies depth and a body of knowledge, not just exposure. This is the right verb for naming your major, your field, or anything you are investigating.
Она́ изуча́ет кита́йскую филосо́фию в аспиранту́ре.
She studies Chinese philosophy as a postgraduate. — изуча́ть + accusative: a serious academic subject.
Учёные мно́го лет изуча́ли пове́дение э́тих птиц.
Scientists studied the behaviour of these birds for many years. — изуча́ть = research / investigate in depth.
The perfective изучи́ть means to have studied something to the point of mastering or thoroughly knowing it: Я изучи́л все докуме́нты ("I've studied all the documents [completely]").
Занима́ться: work on it, practise it, engage in it
Занима́ться + instrumental is the broadest of the four and the one whose government surprises everyone. It means "to be occupied with / engage in / work on / practise" — an activity, a hobby, a sport, a subject you are putting effort into. The thing you do goes in the instrumental, with no preposition.
По вечера́м я занима́юсь ру́сским языко́м с репети́тором.
In the evenings I work on Russian with a tutor. — занима́ться + instrumental ру́сским языко́м.
Мой брат серьёзно занима́ется пла́ванием и хо́дит на трениро́вки ка́ждый день.
My brother does swimming seriously and goes to training every day. — занима́ться + instrumental спо́рт/пла́вание.
Не меша́й, я занима́юсь.
Don't disturb me, I'm studying / busy working. — занима́ться used absolutely = 'do one's studies / be busy'.
Notice that занима́ться also stands alone to mean "do one's studies / be busy working" — Я це́лый день занима́лся ("I studied / worked all day"). For its full range, see заниматься.
"I'm studying Russian" — three correct answers
The English sentence "I'm studying Russian" maps onto three Russian verbs, and the choice signals how you are studying it:
| Russian | Nuance |
|---|---|
| Я изуча́ю ру́сский (язы́к). | I study Russian as a subject / academically (the most neutral and formal). |
| Я учу́ ру́сский. | I'm learning Russian (everyday, often the practical "learning words/phrases" sense). |
| Я занима́юсь ру́сским (языко́м). | I'm working on / practising Russian (the activity of studying, often regularly). |
All three are correct; none is interchangeable with учу́сь ру́сский, which simply does not exist. Note that учи́ть in the everyday "learn a language" sense (учу́ ру́сский) is common in speech but takes the language as a direct *accusative — distinct from учи́ться, which takes no object at all.
— Что ты сейча́с изуча́ешь? — Я учу́ коре́йский и понемно́гу занима́юсь япо́нским.
— What are you studying these days? — I'm learning Korean and dabbling a bit in Japanese. — all three verbs, each with its own government.
The distinguishing insight: it is government, not vocabulary
The reason this set is hard is that English chose to make "study / learn / teach" do everything, while Russian distributes the work and welds a case onto each verb. So the reliable strategy is not "which word means study?" but "which frame am I in?" — and each frame comes with its case pre-attached: учи́ть pulls the accusative (a thing to memorize) or acc. + dative (teach someone a subject); учи́ться pulls a location or an infinitive, never an object; изуча́ть pulls the accusative of a field; занима́ться pulls the instrumental. Learn the verb together with its case, the way you learn a noun together with its gender, and the four stop blurring.
Common Mistakes
❌ Я учу́сь ру́сский язы́к в университе́те.
Wrong — учи́ться takes no direct object. Use изуча́ю ру́сский (subject) or занима́юсь ру́сским (activity).
✅ Я изуча́ю ру́сский язы́к в университе́те.
I study Russian at university. — изуча́ть + accusative for a subject.
❌ Я занима́юсь ру́сский язы́к ка́ждый день.
Wrong case — занима́ться governs the instrumental, not the accusative: ру́сским языко́м.
✅ Я занима́юсь ру́сским языко́м ка́ждый день.
I work on Russian every day. — занима́ться + instrumental.
❌ Учи́тель у́чит нас матема́тику.
Wrong case — in the 'teach' sense the subject goes in the dative: матема́тике.
✅ Учи́тель у́чит нас матема́тике.
The teacher teaches us maths. — учи́ть + accusative person (нас) + dative subject (матема́тике).
❌ Учёные у́чат пове́дение живо́тных.
Wrong verb — for serious, in-depth study of a subject you need изуча́ть, not учи́ть (which is 'memorize' or 'teach').
✅ Учёные изуча́ют пове́дение живо́тных.
Scientists study animal behaviour. — изуча́ть for in-depth research.
❌ Я хочу́ изуча́ть пла́вать.
Wrong — 'learn how to do something' is учи́ться + infinitive, not изуча́ть.
✅ Я хочу́ научи́ться пла́вать.
I want to learn to swim. — учи́ться/научи́ться + infinitive.
Key Takeaways
- учи́ть + accusative = memorize (учи́ть слова́); учи́ть + acc. person + dative subject = teach (учи́ть дете́й матема́тике).
- учи́ться = be a student / learn how to; it takes a location or an infinitive and never a direct object (учи́ться в шко́ле, учи́ться чита́ть).
- изуча́ть + accusative = study a subject in depth, academically (изуча́ть фи́зику).
- занима́ться + instrumental = work on / practise / engage in (занима́ться ру́сским, спо́ртом) — the instrumental is the most-missed government.
- "I study Russian" has three correct verbs by nuance: изуча́ю (academic), учу́ (everyday learning), занима́юсь (the activity) — but never *учу́сь ру́сский.
- Learn each verb together with the case it governs, not just its English gloss.
