This is one of the hardest vocabulary knots in Russian for English speakers, because the mapping is not one-to-one in either direction. English learn, study, and teach scatter across five Russian verbs, and the most frequent of them — учи́ть — is itself dangerously ambiguous, meaning both "memorize" and "teach" depending only on its grammatical objects. The good news is that Russian disambiguates by case government: the case of the object tells you which meaning is active. Once you learn to read the cases, the verbs sort themselves out.

Start with the destination. Here is what each English idea becomes in Russian:
| You mean... | Russian verb | Government |
|---|---|---|
| memorize / learn by heart | учи́ть / вы́учить |
|
| teach someone something | учи́ть / научи́ть | acc. person + dat. subject |
| be a student / learn a skill | учи́ться / научи́ться |
|
| study a subject academically | изуча́ть / изучи́ть |
|
| be engaged in / work on | занима́ться | |
| teach professionally | преподава́ть |

The single most useful habit is to notice that учи́ть appears in the first two rows with opposite meanings, separated only by what follows it. Everything below unpacks that.
учи́ть — the two-faced verb
Учи́ть (impf.; perfectives вы́учить "memorize" / научи́ть "teach") carries two meanings that share no overlap in English:
Sense 1 — memorize / learn by heart, with a direct object in the accusative. You учи́ть the things you commit to memory: vocabulary, a poem, the rules, a role.
Я ка́ждый ве́чер учу́ но́вые слова́.
Every evening I learn new words. — учи́ть + accusative слова́ = memorize.
Она́ всю неде́лю учи́ла стихотворе́ние наизу́сть.
She spent all week learning the poem by heart. — учи́ть + acc. = commit to memory.
Sense 2 — teach someone something, with the person in the accusative and the subject taught in the dative. The dative here is the "thing imparted." This is the construction that most surprises English speakers, because the same verb just meant the opposite.
Де́душка у́чит вну́ка ша́хматам.
Grandfather is teaching his grandson chess. — учи́ть + acc. person (вну́ка) + dat. subject (ша́хматам) = teach.
Кто научи́л тебя́ так гото́вить?
Who taught you to cook like that? — научи́ть + acc. person (тебя́) + infinitive (гото́вить) = teach to do.
учи́ться — to be a student, to learn a skill
Add the reflexive -ся and the meaning turns inward: учи́ться is what the learner does. It covers two everyday English ideas:
- be a student / study (somewhere) — учи́ться в университе́те ("study at university"), with the place in the prepositional;
- learn (to do something) — either учи́ться + dative (учи́ться му́зыке "learn music") or учи́ться + infinitive (учи́ться пла́вать "learn to swim").
The perfective научи́ться ("learn (to), master") is used for the completed acquisition of a skill.
Я учу́сь в университе́те на тре́тьем ку́рсе.
I'm a third-year student at the university. — учи́ться = be a student.
Сын у́чится игра́ть на гита́ре.
My son is learning to play the guitar. — учи́ться + infinitive = learn to do.
В э́том году́ я наконе́ц научи́лся води́ть.
This year I finally learned to drive. — научи́ться, the completed acquisition of a skill.
Note the neat symmetry with sense 2 of учи́ть: Я учу́ сы́на пла́вать ("I teach my son to swim") and Сын у́чится пла́вать ("My son learns to swim") are two sides of the same lesson — the -ся simply turns the teacher's verb into the learner's verb.
изуча́ть — to study a subject in depth
Изуча́ть (impf.; pf. изучи́ть) means to study a subject academically, systematically, in depth. It takes a direct object in the accusative and implies serious, ongoing engagement — the verb of scholars, researchers, and university courses. This is the verb for "study Russian," "study history," "study the market."
Я изуча́ю ру́сский язы́к уже́ два го́да.
I've been studying Russian for two years now. — изуча́ть + accusative: serious, in-depth study of a subject.
Учёные изуча́ют поведе́ние дельфи́нов.
Scientists study the behaviour of dolphins. — изуча́ть = investigate systematically.
There is overlap with учи́ть here: учи́ть ру́сский and изуча́ть ру́сский both mean "learn/study Russian," but изуча́ть sounds more academic and thorough, while учи́ть язы́к leans toward the active, day-to-day grind of acquiring it. For school subjects either can appear; for research and deep study, изуча́ть is the natural choice.
занима́ться — to be engaged in, to work on
Занима́ться (reflexive) takes the instrumental case and means "be occupied with / engage in / work on." It is the verb for the activity of studying or practising, and for pursuits generally — sports, hobbies, fields of work.
По вечера́м я занима́юсь матема́тикой.
In the evenings I study/work on maths. — занима́ться + instrumental: the activity of studying.
Он профессиона́льно занима́ется спо́ртом.
He does sports professionally. — занима́ться + instr. for pursuits in general.
The contrast with изуча́ть is the contrast between the activity and the subject matter: изуча́ю исто́рию (acc.) frames history as the body of knowledge you are mastering; занима́юсь исто́рией (instr.) frames it as the activity occupying your time. Used absolutely, Я занима́юсь simply means "I'm studying / doing my work right now."
преподава́ть — to teach professionally
Преподава́ть is the professional "teach" — what an instructor does for a living. It takes the accusative for the subject taught and an optional dative for the audience. Note its present-tense forms: it is an -ава- verb that drops the -ва- (преподаю́, преподаёшь, преподаёт, преподаю́т), like дава́ть.
Она́ преподаёт фи́зику в шко́ле.
She teaches physics at a school. — преподава́ть + accusative subject: teach as a profession.
Профе́ссор Ивано́в преподаёт нам литерату́ру.
Professor Ivanov teaches us literature. — + dative audience (нам).
Compare the two "teach" verbs: учи́ть is the everyday "teach" (a parent teaching a child, a friend showing you how), built with acc. person + dat. subject; преподава́ть is the institutional "teach" (a teacher's profession), built with an acc. subject. You у́чишь your child to read; you преподаёшь mathematics at a school.
A full disambiguation set
Watch the same three nouns — Russian, the university, a child — flow through the cluster:
Я изуча́ю ру́сский язы́к в университе́те.
I study Russian at university. — изуча́ть, the academic subject.
Я учу́сь в университе́те.
I'm a student at the university. — учи́ться, being a student.
Я учу́ ру́сские слова́ ка́ждый день.
I learn Russian words every day. — учи́ть + acc., memorizing.
Я учу́ ребёнка чита́ть по-ру́сски.
I'm teaching my child to read in Russian. — учи́ть + acc. person + infinitive, teaching.
Я преподаю́ ру́сский язы́к иностра́нцам.
I teach Russian to foreigners. — преподава́ть, the profession.
Common Mistakes
❌ Я учу́сь ру́сский язы́к.
Wrong — учи́ться cannot take a direct object. To 'learn/study Russian' use учу́ ру́сский (учи́ть + acc.) or изуча́ю ру́сский (изуча́ть + acc.).
✅ Я изуча́ю ру́сский язы́к.
I'm studying Russian.
❌ Он у́чит фи́зику в шко́ле (meaning 'he teaches physics').
Wrong — учи́ть + bare acc. means 'memorize'; this reads as 'he is memorizing physics.' For 'teach a subject professionally' use преподаёт.
✅ Он преподаёт фи́зику в шко́ле.
He teaches physics at school.
❌ Я занима́юсь матема́тику.
Wrong — занима́ться takes the instrumental, not the accusative: матема́тикой.
✅ Я занима́юсь матема́тикой.
I'm studying maths.
❌ Учи́тель у́чит дете́й матема́тику.
Wrong — when учи́ть means 'teach,' the subject taught goes in the dative: матема́тике, not the accusative.
✅ Учи́тель у́чит дете́й матема́тике.
The teacher teaches the children maths.
❌ Я хочу́ учи́ть пла́вать.
Wrong — to 'learn to swim' (the learner's side) use the reflexive учи́ться: учи́ться пла́вать. Учи́ть пла́вать means 'teach someone to swim.'
✅ Я хочу́ научи́ться пла́вать.
I want to learn to swim.
Key Takeaways
- учи́ть is two-faced: with a bare accusative (учу́ слова́) it means memorize; with an accusative person + dative subject / infinitive (учу́ сы́на ма́тематике / чита́ть) it means teach.
- учи́ться (reflexive) is the learner's verb: be a student (учу́сь в университе́те) or learn to do (учи́ться пла́вать); it takes the dative or an infinitive, never a direct object.
- изуча́ть (+ acc.) is the academic study a subject in depth: изуча́ть ру́сский язы́к, изуча́ть исто́рию.
- занима́ться (+ instr.) is be engaged in / work on — the activity, not the subject matter: занима́ться матема́тикой, спо́ртом.
- преподава́ть (+ acc. subject, present преподаю́/преподаёшь) is the professional teach: Она́ преподаёт фи́зику.
- The cases do the disambiguating — read the case frame and the verb's meaning falls out.

- Knowing and Being Able: Знать, Уметь, МочьA2 — English collapses three distinct ideas into 'know how' and 'can'; Russian keeps them apart. знать = know facts, information, people, a language as knowledge; уме́ть = know how to (a learned skill); мочь = be able to in a given situation (possibility, circumstance, permission). Covers why 'I can swim' is уме́ю but 'I can come' is могу́, why знать never means 'know how,' and how the perfective узна́ть shifts to 'find out / recognize.'
- Dative: The Indirect ObjectA2 — The dative's core job is the indirect object — the recipient or beneficiary, answering кому? (to whom?). The frame is subject (nom) + verb + thing (acc) + recipient (dat): Я дал дру́гу кни́гу (I gave my friend a book), Она́ написа́ла письмо́ ма́ме. The trap for English speakers is a closed list of verbs that take the dative where English uses a plain direct object — помога́ть (help), звони́ть (phone), сове́товать (advise), ве́рить (believe), меша́ть (bother), ра́доваться (be glad about) — so 'I help my brother' is Я помога́ю бра́ту (dat), not *брата.
- Instrumental: Means and InstrumentA2 — The instrumental's namesake job: it marks the tool or means by which an action is done — and it does so with NO preposition. Писа́ть ру́чкой (write with a pen), е́хать по́ездом (go by train). Beware: с + instrumental means 'together with' (чай с са́харом), so never insert с for a tool. The case also gives time-of-day adverbs (у́тром, ве́чером) and is required by verbs like занима́ться and интересова́ться.
- Accusative: The Direct ObjectA1 — The accusative marks the direct object — the thing a transitive verb acts on directly. Verbs like чита́ть, смотре́ть, люби́ть, ви́деть, знать all take an accusative object (чита́ть кни́гу, люби́ть му́зыку). Because Russian word order is free, the case ending — not position — tells you which noun is being acted upon, so every direct object must be marked. Object pronouns (меня́, тебя́, его́, её, нас, вас, их) are accusative too.
- Putting Things: Класть/Положить, Ставить/Поставить, Вешать/ПовеситьB1 — Russian splits the single English verb 'put' into three verbs chosen by the resulting orientation of the object: класть/положи́ть (put down flat/lying), ста́вить/поста́вить (put upright/standing), and ве́шать/пове́сить (hang). Covers the suppletive класть/положи́ть pair (never *ло́жить), the accusative-of-destination construction, and how each verb maps to its 'be located' counterpart.
- Verbal Aspect: The Big PictureA2 — Aspect is the spine of the Russian verb: nearly every verb belongs to a pair — imperfective (process, repetition, general fact) and perfective (a single completed whole with a result). This page explains the pair, the consequences for the tense system (perfectives have no present), and why you must decide 'process or result?' before you even pick a tense.
