Few topics expose Russian grammar as cleanly as work and study. Your profession comes out in the instrumental (рабо́тать инжене́ром, "to work as an engineer"), where you study takes the prepositional (учи́ться в университе́те), what you study takes the accusative (изуча́ть фи́зику), and your field follows специали́ст по + dative. On top of that sit two notorious splits English flattens: the aspect pair сдава́ть ("to sit/take an exam") versus сдать ("to pass it"), and the three-way учи́ть / учи́ться / изуча́ть for "to learn/study/teach." Master this page and you can introduce your career and education accurately — and you've drilled three cases plus an aspect contrast in one practical sweep.
Your profession: рабо́тать + instrumental
To say what you do for a living, use рабо́тать ("to work") plus the profession in the instrumental — the case of "in the capacity of." Literally "I work as an engineer": Я рабо́таю инжене́ром. This is the same instrumental that turns up in Он стал врачо́м ("he became a doctor"). The profession isn't an object; it's the role you occupy.
| Profession (nom) | Instrumental | English |
|---|---|---|
| инжене́р | инжене́ром | (as) an engineer |
| учи́тель | учи́телем | (as) a teacher |
| врач | врачо́м | (as) a doctor |
| программи́ст | программи́стом | (as) a programmer |
| медсестра́ | медсестро́й | (as) a nurse |
| перево́дчик | перево́дчиком | (as) a translator |
Я рабо́таю программи́стом в небольшо́й компа́нии.
I work as a programmer at a small company. — рабо́тать + instrumental программи́стом; в + prepositional компа́нии.
Ра́ньше она́ рабо́тала учи́телем, а тепе́рь перево́дчиком.
She used to work as a teacher, and now as a translator. — both professions instrumental: учи́телем, перево́дчиком.
Кем ты рабо́таешь?
What do you do for a living? (lit. as whom do you work?) — кем is the instrumental of кто; the standard 'what's your job?'.
Where you study: учи́ться в / на + prepositional
For "to study (somewhere)" — to be a student at an institution — use учи́ться (reflexive) plus the place in the prepositional: учи́ться в университе́те ("at university"), в шко́ле ("at school"). Some institutions take на rather than в, especially faculties and courses: на физи́ческом факульте́те ("in the physics department"), на пе́рвом ку́рсе ("in first year").
| Russian | English |
|---|---|
| учи́ться в университе́те | to study at university |
| учи́ться в шко́ле | to be at school |
| учи́ться на пе́рвом ку́рсе | to be in first year |
| учи́ться на ю́риста | to study to be a lawyer (на + acc!) |
| око́нчить университе́т | to graduate from university |
Я учу́сь в университе́те на тре́тьем ку́рсе.
I'm in my third year at university. — учи́ться в + prepositional университе́те; на + prepositional ку́рсе for the year.
Он у́чится на врача́.
He's studying to become a doctor. — на + accusative врача́ for the target profession ('studying toward being a doctor').
По́сле шко́лы она́ поступи́ла в институ́т.
After school she got into college. — поступи́ть в + accusative институ́т ('enrol/get into'); по́сле + genitive шко́лы.
The учи́ть / учи́ться / изуча́ть knot
English uses "study" and "learn" loosely; Russian splits the territory three ways, and English speakers mix them up constantly.
- изуча́ть + accusative — "to study (a subject) systematically, in depth." Я изуча́ю фи́зику ("I study physics"). The most academic of the three.
- учи́ть + accusative — "to learn / memorise (something specific)," or "to teach (someone)." Я учу́ слова́ ("I'm learning the words"). Context tells you which.
- учи́ться (reflexive) — "to study (be a student)" or "to learn (how to do something)" with an infinitive: учи́ться води́ть ("to learn to drive").
| Verb | Takes | Means |
|---|---|---|
| изуча́ть | accusative subject | study a subject in depth |
| учи́ть | accusative thing / person | memorise; or teach someone |
| учи́ться | в/на + prep, or infinitive | be a student; learn to do X |
Я изуча́ю ру́сский язы́к в университе́те.
I study Russian at university. — изуча́ть + accusative язы́к: systematic study of a subject.
Мне ну́жно вы́учить э́ти слова́ к экза́мену.
I need to learn these words for the exam. — вы́учить (perfective of учи́ть) + accusative слова́: memorise specific items.
Сестра́ у́чится води́ть маши́ну.
My sister is learning to drive. — учи́ться + infinitive: 'learn to do something'.
Exams: сдава́ть (sit) vs сдать (pass)
This is the aspect contrast that catches everyone, because the same root means two different outcomes depending on aspect. The imperfective сдава́ть means "to sit / take an exam" — the process, with no implication you passed. The perfective сдать means "to pass it" — the successful result. So Я сдава́л экза́мен три ра́за ("I took the exam three times") can imply you kept failing, while Я сдал экза́мен ("I passed the exam") states success.
| Aspect | Verb | Means |
|---|---|---|
| imperfective | сдава́ть | to sit / take (the process) |
| perfective | сдать | to pass (the result) |
За́втра я сдаю́ экза́мен по матема́тике.
Tomorrow I'm sitting the maths exam. — сдаю́ (imperfective сдава́ть): the process, no claim of passing; по + dative for the subject.
Я сдал экза́мен на пятёрку!
I passed the exam with top marks! — сдал (perfective сдать): the successful result.
Она́ два ра́за сдава́ла на права́ и нако́нец сдала́.
She took the driving test twice and finally passed. — сдава́ла (took, twice) vs сдала́ (passed, once).
Field, colleagues, and the workplace
A few more high-frequency pieces. Your specialism is специали́ст по + dative ("a specialist in…"): специали́ст по марке́тингу. Your coworker is a колле́га (same form for men and women — it ends in -а but takes the gender of the person). Your boss is нача́льник (m) / нача́льница (f). To "do / be engaged in" an activity or field, use занима́ться + instrumental.
Она́ специали́ст по междунаро́дному пра́ву.
She's a specialist in international law. — специали́ст по + dative пра́ву; the adjective agrees in the dative.
Мой колле́га занима́ется ма́ркетингом.
My colleague works in marketing. — занима́ться + instrumental ма́ркетингом; колле́га takes masculine agreement here (a man).
Я поговорю́ об э́том с нача́льником.
I'll talk to my boss about this. — с + instrumental нача́льником; об + prepositional э́том.
How this differs from English
English leans on prepositions and a single flexible verb where Russian uses case endings and several verbs. "Work as an engineer" becomes a bare instrumental (инжене́ром) — no word for "as" at all. "Study at university" splits its object by case: location is prepositional (в университе́те), but the goal profession is accusative after на (на врача́). English "study" alone covers Russian's изуча́ть / учи́ть / учи́ться, which carve up subject-study, memorising, and being-a-student. And English "take an exam" hides what Russian makes explicit through aspect: сдава́ть (you sat it) versus сдать (you passed). The grammar is doing semantic work that English offloads onto context — so the payoff for learning the patterns is real precision.
Common Mistakes
❌ Я рабо́таю как инжене́р. / Я рабо́таю инжене́р.
No 'как', and the profession is INSTRUMENTAL: рабо́таю инжене́ром.
✅ Я рабо́таю инжене́ром.
I work as an engineer. — instrumental инжене́ром.
❌ Я изуча́юсь в университе́те. / Я учу́ в университе́те.
To be a student somewhere is учи́ться (reflexive): учу́сь в университе́те. (учу́ = memorise/teach; изуча́ть = study a subject.)
✅ Я учу́сь в университе́те.
I study at university. — учи́ться + в + prepositional.
❌ Я изуча́ю слова́ к экза́мену.
For memorising specific items use учи́ть/вы́учить, not изуча́ть (which is for whole subjects): учу́ слова́.
✅ Я учу́ слова́ к экза́мену.
I'm learning the words for the exam. — учи́ть for specific material.
❌ Вчера́ я сдал экза́мен, но не сдал.
Contradiction — perfective сдал already means 'passed'. For the attempt use the imperfective: сдава́л.
✅ Вчера́ я сдава́л экза́мен, но не сдал.
Yesterday I sat the exam but didn't pass. — сдава́л (sat) vs не сдал (didn't pass).
❌ Она́ специали́ст в марке́тинге.
The field after специали́ст is по + DATIVE, not в + prepositional: специали́ст по марке́тингу.
✅ Она́ специали́ст по марке́тингу.
She's a marketing specialist. — специали́ст по + dative.
Key Takeaways
- Profession = рабо́тать + instrumental: рабо́таю инжене́ром, учи́телем, врачо́м. The question is Кем ты рабо́таешь? (instrumental of кто).
- Where you study = учи́ться в/на + prepositional (в университе́те); but на + accusative for the goal profession (учи́ться на врача́).
- The verb knot: изуча́ть + acc = study a subject; учи́ть/вы́учить + acc = memorise (or teach someone); учи́ться = be a student / learn to do something.
- Exam aspect: сдава́ть = to sit/take (process, no success implied); сдать = to pass (result). Only сдал/сдала́ means success.
- Field = специали́ст по + dative (по марке́тингу); colleague = колле́га; boss = нача́льник / нача́льница; занима́ться + instrumental for "be engaged in."

- Работать (to work)A1 — Complete conjugation-and-usage reference for рабо́тать 'to work' — the model fully-regular first-conjugation -ай verb (рабо́таю / рабо́таешь / рабо́тают, fixed root stress). Full present, past, future, imperative, participle, and verbal-adverb tables, plus the three government patterns that trip English speakers: рабо́тать + instrumental of profession (рабо́тать учи́телем), над + instrumental ('work on'), and в/на + prepositional (place of work), with the delimitative perfective порабо́тать ('work a while').
- Instrumental as Predicate (Profession, Becoming)B1 — When 'to be / become / work as / seem' link a subject to a role or state, the role takes the instrumental — especially in the past and future: Он был врачо́м, Она́ ста́ла учи́тельницей. The key contrast: the PRESENT tense uses the nominative (Он врач), but past/future быть and the verbs стать, рабо́тать, каза́ться switch the predicate to the instrumental. Являться always takes the instrumental, even in the present.
- Taking vs Passing an Exam: Сдавать / СдатьB1 — With экза́мен, the aspect of one verb flips the meaning. СДАВА́ТЬ (imperfective) = to TAKE / SIT an exam — the process, no success implied. СДАТЬ (perfective) = to PASS it — the successful result. So Сдава́л, но не сдал = 'I took it but didn't pass.' Mistaking сдать for merely 'take' makes you claim to have passed.
- Learning and Teaching: Учить, Учиться, Изучать, ПреподаватьB1 — English blurs learn, study, and teach into a handful of verbs; Russian splits them into a cluster governed by case. учи́ть = memorize (+ acc.) OR teach someone something (acc. person + dat. subject); учи́ться = be a student / learn a skill (+ dat. or inf.); изуча́ть = study a subject academically (+ acc.); занима́ться = be engaged in / work on (+ instr.); преподава́ть = teach professionally (+ acc.). Disambiguation tables and the case government that tells them apart.
- Учиться / Заниматься (study, reference)A2 — A decision-guide and conjugation reference for the two main 'study' reflexives: учи́ться (учу́сь, у́чишься, у́чатся) — to be a student, with в + prepositional 'study at', + dative 'learn a subject', + infinitive 'learn to' — versus занима́ться, which takes a bare instrumental and means 'work on / practise / be engaged in' (занима́ться ру́сским / спо́ртом). The line: учи́ться is about being-a-student; занима́ться is about doing-the-activity.
- Prepositional for Location (в and на)A1 — The prepositional's main job: saying WHERE something is, after в (in/at, enclosed) and на (on/at a surface or event). В Москве́, в шко́ле, на столе́, на рабо́те. The big contrast: location takes the prepositional (Я в шко́ле) but motion-to takes the accusative (Я иду́ в шко́лу) — same prepositions, different case. Plus the lexical на-list you must memorize.
