Russian Prepositions & Their Cases
A Russian preposition is never alone: each one demands a case from the noun that follows. Fight this and every sentence breaks; embrace it — learn preposition + case as one package — and endings start taking care of themselves.
Prepositions Come With a Case
Compare:
Я живу в Москве.
I live in Moscow.
Note: в + prepositional case (location): Москва → Москве.
Я еду в Москву.
I'm going to Moscow.
Note: Same в, but + accusative (motion): Москва → Москву.
Same preposition, different case, different meaning. This is why you learn the pair, not the preposition alone.
в and на: Location vs Motion
The two most common prepositions both play the location/motion game:
в = in/into (enclosed spaces); на = on/at (surfaces, events, open spaces). Some nouns conventionally take на — работа, почта, концерт, рынок, урок — learn them as set phrases.
The Genitive Crew
A whole gang of prepositions takes the genitive. The big four:
Кофе без молока, пожалуйста.
Coffee without milk, please.
Note: без + genitive: молоко → молока. Instantly useful.
💬 Ordering coffee
Я из Германии. А вы откуда?
I'm from Germany. And where are you from?
Note: из + genitive: Германия → Германии. Откуда = where from.
к, с, о: One Each
Я пью кофе с молоком и говорю с другом о работе.
I'm drinking coffee with milk and talking with a friend about work.
Note: Three preposition+case packages in one natural sentence: с + instr., с + instr., о + prep.
The Cheat Sheet
Common Mistakes
- Picking the case by feel. The preposition decides, always. Learn в школу / в школе as two flashcards.
- Using в with работа. It's на работе / на работу — the на-nouns are a fixed list.
- Saying с when nothing accompanies. "I write with a pen" uses bare instrumental, no с: Я пишу ручкой. С is for company: с другом.
- Confusing из and с for "from". From a в-place use из (из школы); from a на-place use с (с работы). Mirror logic.
What You Can Do Now
You can place yourself in the world and move through it: Я на работе. Я иду в кафе с другом. Это подарок для мамы. Combined with the cases lesson, the ending system is now fully in your hands.
