Prepositions and Case: How They Work Together | Russian Grammar

In English a preposition is a free-floating word: in the house, to the house, from the house — the noun "house" never changes, and you pick the preposition on its own. Russian works on a completely different principle. Every preposition governs a case — it forces the noun after it into a particular form — and a preposition is never used by itself. This means you can never learn a Russian preposition as a bare word. You learn it together with the case it demands, the way you learn the gender along with a noun. из is not just "from" — it is "from + genitive." к is not just "to" — it is "to + dative." Get this idea first and the whole system becomes a map you can navigate instead of a list you have to memorize.

A preposition is never used alone

The noun after a preposition always wears a case ending. Compare how English keeps "school" frozen while Russian re-shapes шко́ла each time:

Я в шко́ле, иду́ из шко́лы, иду́ к шко́ле.

I'm at school, I'm coming from school, I'm walking toward the school. (one English noun 'school' — three Russian forms: шко́ле, шко́лы, шко́ле, each demanded by its preposition)

The preposition picks the case; the case shapes the noun. You can't supply one without the other.

💡

Never store a preposition in your memory as a lone word. Store the pair: без + genitive, к + dative, про + accusative, о + prepositional. The case is half of what the preposition is.

The map: which prepositions take which case

Most prepositions are loyal to a single case. Here is the everyday core, grouped by the case each one governs. The full case-by-case treatment lives on case after prepositions; the dedicated pages drill each group.

Case governed	Common prepositions	Core meanings
Genitive	из, от, до, у, для, без, о́коло, по́сле, про́тив, кро́ме, вокру́г	from / out of, until, at, for, without, near, after
Dative	к, по	toward / to (a person), along / around / according to
Accusative	в, на, за, под, че́рез, про	motion-into, motion-onto, in (time) / behind-to, in/after (time), about
Instrumental	с, над, под, пе́ред, ме́жду, за	with, above, under, in front of, between, behind
Prepositional	о (об), при, в, на	about, at the time of / by, in / on (location)

One example from each group. Watch the ending on every noun.

Я получи́л письмо́ от дру́га без а́дреса.

I got a letter from a friend with no return address. (от, без both genitive: дру́га, а́дреса)

Мы идём к врачу́ по гла́вной у́лице.

We're walking to the doctor's along the main street. (к, по both dative: врачу́, гла́вной у́лице)

Положи́ де́ньги в су́мку и позвони́ че́рез час.

Put the money in the bag and call in an hour. (в, че́рез both accusative here: су́мку, час)

Я живу́ с роди́телями над магази́ном.

I live with my parents above a shop. (с, над both instrumental: роди́телями, магази́ном)

Мы говори́ли о рабо́те при дире́кторе.

We talked about work in the director's presence. (о, при both prepositional: рабо́те, дире́кторе)

The two-case prepositions: case carries the meaning

A small set of very common prepositions takes two different cases, and the choice of case is not random — it changes what the sentence means. This is the most important structural idea on the page, and the place where beginners make the most errors. With these, you have to decide the meaning first, then pick the case.

Preposition	Accusative	another case
в / на	motion into / onto — куда? (в шко́лу)	prepositional = location in / on — где? (в шко́ле)
за / под	motion to behind / under — куда? (за стол)	instrumental = location behind / under — где? (за столо́м)
с	—	genitive = from / off (с рабо́ты); + instrumental = with (с дру́гом)

For в and на, the accusative means you are aiming at a place (motion toward), while the prepositional means you are at it (static location) — same preposition, opposite ideas, decided purely by the ending. The dedicated page is в and на: in/on vs into/onto.

Я иду́ в шко́лу. Тепе́рь я в шко́ле.

I'm going to school. Now I'm at school. (в + accusative шко́лу = motion; в + prepositional шко́ле = location)

For за and под, the accusative is "to behind / to under" (motion), the instrumental is "behind / under" (location):

Кот забежа́л за дива́н и сиди́т за дива́ном.

The cat ran behind the sofa and is sitting behind the sofa. (за + accusative дива́н = motion; за + instrumental дива́ном = location)

And с depends on meaning entirely: genitive for "from / off," instrumental for "with" (two different words that happen to share a spelling):

Я пришёл с рабо́ты с дру́гом.

I came from work with a friend. (с + genitive рабо́ты = 'from'; с + instrumental дру́гом = 'with')

Prepositions are pronounced as one word with the noun

Russian prepositions are clitics — they carry no stress of their own and lean phonologically onto the following word, so the pair is pronounced as a single chunk. в шко́ле comes out as one word, fshkólye; в itself reduces to just an [f] sound before the voiceless ш. This is why you don't pause after a preposition, and why short prepositions sometimes grow a vowel before hard clusters: во Фра́нции, со мной, обо мне, ко мне — the extra о is purely to make the chunk pronounceable.

Он живёт во Фра́нции и рабо́тает со мной.

He lives in France and works with me. (во, со — the vowel is added so в/с can attach to the cluster; pronounced as one chunk with the next word)

A practical knock-on effect: after a preposition, the third-person pronouns он / она́ / они́ add an н-, becoming него́ / неё / них (у него́, к ней, с ни́ми) — a euphonic relic of this tight phonological bond, covered on the н- after prepositions page.

Common Mistakes

❌ Я иду́ к до́ктор.

Incorrect — к governs the dative; до́ктор → до́ктору. A preposition can never be followed by a bare nominative.

✅ Я иду́ к до́ктору.

I'm going to the doctor. (к + dative до́ктору)

❌ Я в шко́лу. (meaning 'I'm at school')

Incorrect for location — accusative шко́лу means motion 'to school.' Being AT school is в + prepositional: в шко́ле.

✅ Я в шко́ле.

I'm at school. (в + prepositional = location)

❌ Я живу́ Москва́.

Incorrect — 'in Moscow' needs the preposition в plus the prepositional: в Москве́. You can't express location with a bare noun.

✅ Я живу́ в Москве́.

I live in Moscow. (в + prepositional Москве́)

❌ Я пришёл с рабо́той.

Wrong case for 'from work' — с + instrumental рабо́той means 'with work.' 'From work' is с + genitive: с рабо́ты.

✅ Я пришёл с рабо́ты.

I came from work. (с + genitive рабо́ты)

Key Takeaways

Every Russian preposition governs a case and is never used alone — learn each preposition together with its case (без + genitive, к + dative, о + prepositional).
The everyday core: genitive (из, от, до, у, для, без, о́коло…), dative (к, по), accusative (в, на, за, под, че́рез, про), instrumental (с, над, под, пе́ред, ме́жду), prepositional (о, при, plus в/на for location).
A few prepositions take two cases, and the case carries the meaning: в/на (accusative = motion, prepositional = location), за/под (accusative = motion, instrumental = location), с (genitive = from, instrumental = with).
Prepositions are clitics: pronounced as one chunk with the noun (в шко́ле = fshkólye), sometimes growing a vowel (во, со, ко, обо), and triggering the н- on он/она́/они́ (у него́, к ней).
