The Accusative: Functions Summary

This page pulls the whole accusative case (вини́тельный паде́ж, vinítelny padézh — "the accusative case") together on one screen: every form, every function, and the one insight that ties them together. Treat it as a review and a map — each function links out to a full lesson where you can drill it. If you only remember one thing, remember this: the accusative is not just "the object case." It is also the case of destination, duration, points in time, and future intervals — so its endings turn up in motion and time expressions, not only after verbs like "to see" and "to read."

The forms at a glance

The accusative's reputation for difficulty comes entirely from one quirk: for many nouns its ending is borrowed from another case, so there is no single "accusative shape." Here is the complete singular-and-plural picture.

Gender / type	Nominative	Accusative	Borrowed from
Feminine -а/-я	кни́га (book), неде́ля (week)	кни́гу, неде́лю	its own ending (-у/-ю)
Masc. / neut. inanimate	стол (table), окно́ (window)	стол, окно́	= nominative
Masculine animate	брат (brother)	бра́та	= genitive
Feminine -ь	ночь (night), мать (mother)	ночь, мать	unchanged
ALL plural animate	друзья́ (friends), сёстры (sisters)	друзе́й, сестёр	= genitive plural
ALL plural inanimate	столы́, кни́ги	столы́, кни́ги	= nominative plural

So the only ending that is uniquely, visibly accusative is the feminine -у/-ю (кни́гу). Everything else copies the nominative (inanimate) or the genitive (animate). That copying is the animacy rule, and it is worth its own lesson — see the animacy rule. The bare-feminine form is also the easiest entry point if you are just starting; the full paradigm lives on accusative forms.

💡

The accusative has no ending of its own except feminine -у/-ю. For everything else, ask one question: is the noun alive? Alive → use the genitive shape (ви́жу бра́та, друзе́й). Not alive → use the nominative shape (ви́жу стол, столы́). Master that and the accusative is mostly solved.

The uses, one example each

Here is the complete checklist of accusative jobs. Each is the headline of a fuller lesson.

1. The direct object — "what gets the action"

The core use: the thing a transitive verb acts on. This answers кого́? что? ("whom? what?"). Full treatment on the direct object.

Я уже́ прочита́л э́ту кни́гу, могу́ дать тебе́.

I've already read this book, I can give it to you. — кни́гу, direct object (fem -у).

2. The animacy rule in action — animate objects look genitive

For living masculine-singular and all animate plural objects, the accusative copies the genitive. Compare ви́жу стол (table, inanimate = nom) with ви́жу бра́та (brother, animate = gen).

В метро́ я случа́йно встре́тил ста́рого дру́га.

On the metro I accidentally ran into an old friend. — дру́га, animate object = genitive shape.

3. Duration — "for how long" (no preposition)

A bare accusative answers как до́лго? ("for how long?"). No "for," no preposition — the case alone carries it. More on accusative in time and duration.

Я ждал тебя́ всю неде́лю, почему́ ты не звони́л?

I waited for you the whole week — why didn't you call? — всю неде́лю, bare accusative = duration.

4. Clock time and days — в + accusative

For "at what o'clock" and "on what day," Russian uses в + accusative. Note this is a point in time, contrasted with через for intervals (below).

Дава́й встре́тимся в три часа́ в сре́ду у вхо́да.

Let's meet at three o'clock on Wednesday by the entrance. — в три часа́, в сре́ду, points in time = в + accusative.

5. Motion toward — в/на/за/под + accusative

The accusative marks the destination. The very same prepositions that mean "in/on/behind/under" for location (with the prepositional or instrumental) switch to the accusative the instant there is motion toward. The full flip is on accusative after prepositions.

Утром я отвожу́ дете́й в шко́лу, а пото́м е́ду на рабо́ту.

In the morning I take the kids to school, then drive to work. — в шко́лу, на рабо́ту, destinations = accusative.

Поста́вь, пожа́луйста, молоко́ в холоди́льник.

Put the milk in the fridge, please. — в холоди́льник, motion → accusative.

6. Future intervals and "across" — через + accusative

Через + accusative means "in / after" a stretch of time ("an hour from now") and, spatially, "across / through." English speakers reliably misuse в here — for an interval you need через.

Я перезвоню́ тебе́ че́рез час, сейча́с на совеща́нии.

I'll call you back in an hour, I'm in a meeting right now. — че́рез час, future interval (NOT в час).

7. Other accusative prepositions — про, сквозь

Про ("about," informal, the casual cousin of о/об) and сквозь ("through" a resisting medium) also govern the accusative.

Расскажи́ мне про свою́ но́вую рабо́ту, интере́сно!

Tell me about your new job, I'm curious! — про + accusative (informal 'about').

The unifying insight

English marks the object with word order ("I see the brother") and never touches the noun. Russian marks it with the case ending — but the accusative was historically built on top of older nominative and genitive forms, so its ending only survives intact in the feminine -у. Everywhere else it leans on its neighbors: it borrows the nominative for things and the genitive for people.

That borrowing is not arbitrary. The animate-genitive overlap exists precisely so that a sentence like "Mother loves daughter" cannot be misread — мать and дочь would be identical in nominative and accusative, so Russian had no way to tell subject from object. By pulling animate objects into the genitive shape, the language buys back the distinction it needs. Once you see the accusative as a function set unified by meaning, not by a single ending, the "many forms" stop feeling random: object, destination, duration, point-in-time, interval — all of them say the thing the action reaches or the span it covers.

💡

One ending, four meanings: вини́тельный паде́ж answers кого́/что (object), куда́ (destination, в/на/за/под), как до́лго / когда́ (duration bare; point via в), and через (interval/across). When you meet an accusative, ask which of these jobs it is doing — the form is the same, the role is what changes.

Common Mistakes

❌ Я ви́жу мой брат.

Incorrect — брат is animate, so the accusative object copies the genitive: бра́та.

✅ Я ви́жу своего́ бра́та.

I see my brother. — animate object = genitive shape бра́та.

❌ Я иду́ в шко́ле.

Incorrect — with a motion verb, в marks destination and takes the accusative, not the prepositional.

✅ Я иду́ в шко́лу.

I'm going to school. — motion → accusative шко́лу.

❌ Я приду́ в час (intending 'in an hour').

Incorrect — 'в час' means 'at one o'clock'. For an interval from now, use через + accusative.

✅ Я приду́ че́рез час.

I'll come in an hour. — через + accusative for a future interval.

❌ Я ждал тебя́ для всей неде́ли.

Incorrect — duration takes a BARE accusative, no preposition like 'for'.

✅ Я ждал тебя́ всю неде́лю.

I waited for you the whole week. — bare accusative = duration.

❌ Я встре́тил ста́рых друзья́.

Incorrect — all animate plurals take the genitive-plural shape in the accusative: друзе́й.

✅ Я встре́тил ста́рых друзе́й.

I met old friends. — animate plural object = genitive plural друзе́й.

Key Takeaways

The accusative is a function set, not just "the object case": object, destination, duration, point-in-time, and future interval all use it.
Its only unique ending is feminine -у/-ю (кни́гу). Masc./neut. inanimate copy the nominative; animate masc. sg. and all animate plurals copy the genitive; feminine -ь is unchanged.
The animacy rule exists to keep subject and object distinct — that is why бра́та "looks genitive."
в/на/за/под + accusative = motion toward (destination); the same prepositions take the prepositional/instrumental for location.
Time: bare accusative = duration (всю неде́лю); в + acc = clock time and days (в три часа́, в сре́ду); через + acc = future interval (че́рез час), never в час.
