Four of the most common Russian prepositions — в, на, за, под — share a single, beautiful logic. Each takes two cases, and switching the case answers one question: are you moving to a place, or are you already at it? Motion toward a destination ("куда? — where to?") puts the noun in the accusative. Static location ("где? — where?") puts it in another case: the prepositional for в/на, the instrumental for за/под. English collapses this distinction — in the box and into the box often look identical — so the single biggest skill here is learning to feel the difference and let it drive the ending. This page consolidates all four into one map.
The one rule, four prepositions
| Preposition | Motion-to (куда?) → ACCUSATIVE | Location (где?) → other case |
|---|---|---|
| в (in/into) | в шко́лу (to school) | в шко́ле — prepositional (at school) |
| на (on/onto, to) | на рабо́ту (to work) | на рабо́те — prepositional (at work) |
| за (behind) | за стол (behind/to the table) | за столо́м — instrumental (behind the table) |
| под (under) | под стол (under the table) | под столо́м — instrumental (under the table) |
The pattern: motion-to is always accusative, for all four. Location splits — в/на take the prepositional, за/под take the instrumental. That split exists because в/на are "containment" prepositions that have the prepositional case behind them, while за/под belong to the spatial-instrumental family (alongside над, пе́ред, ме́жду).
Я кладу́ кни́гу на стол, и тепе́рь кни́га на столе́.
I'm putting the book on the table, and now the book is on the table. (на + accusative стол = motion 'onto'; на + prepositional столе́ = location 'on')
One noun, all four forms
The cleanest way to see the system is to run a single noun — стол (table) — through every slot. Notice how only the ending and the case-question change:
| Phrase | Case | Question | Meaning |
|---|---|---|---|
| на стол | accusative | куда? | onto the table (motion) |
| на столе́ | prepositional | где? | on the table (location) |
| за стол | accusative | куда? | (to) behind the table (motion — e.g. sitting down) |
| за столо́м | instrumental | где? | behind / at the table (location) |
| под стол | accusative | куда? | (to) under the table (motion) |
| под столо́м | instrumental | где? | under the table (location) |
Сади́тесь за стол — все уже́ сидя́т за столо́м.
Come sit at the table — everyone's already sitting at the table. (за + accusative стол = motion 'taking a seat'; за + instrumental столо́м = location 'seated at')
Мяч закати́лся под стол и лежи́т под столо́м.
The ball rolled under the table and is lying under the table. (под + accusative стол = motion; под + instrumental столо́м = location)
The verb tells you which case
You don't guess motion vs location — the verb decides it. Verbs of going, putting, placing, sitting down (идти́, класть, ста́вить, сади́ться) are directional and demand the accusative. Verbs of being, lying, standing, sitting, living (быть, лежа́ть, стоя́ть, сиде́ть, жить) are static and demand the location case. So the verb is your reliable signal.
Кот забежа́л за дива́н и спря́тался за дива́ном.
The cat ran behind the sofa and hid behind the sofa. (забежа́л — motion → за + accusative дива́н; спря́тался / static result → за + instrumental дива́ном)
And the "from" direction: из / с + genitive
A complete spatial picture has three directions, not two: to, at, and from. The "from" side is handled by из and с + genitive, paired to в and на respectively. Wherever you go в (into), you come из; wherever you go на (onto / to), you come с.
| To (куда?) | At (где?) | From (отку́да?) |
|---|---|---|
| в шко́лу (acc.) | в шко́ле (prep.) | из шко́лы (gen.) |
| на рабо́ту (acc.) | на рабо́те (prep.) | с рабо́ты (gen.) |
У́тром я иду́ на рабо́ту, весь день я на рабо́те, ве́чером возвраща́юсь с рабо́ты.
In the morning I go to work, all day I'm at work, in the evening I come back from work. (на + acc рабо́ту → на + prep рабо́те → с + gen рабо́ты — all three directions of one place)
A journey and an arrival
Put it all together in a single trip. Watch the case track the journey — accusative while you're heading somewhere, the location case the moment you arrive and stay:
Я прие́хал в го́род, останови́лся в гости́нице, поста́вил чемода́н под крова́ть, спря́тал па́спорт за шкаф и сел за стол поу́жинать.
I arrived in the city, stayed in a hotel, put my suitcase under the bed, hid my passport behind the wardrobe, and sat down at the table to have dinner. (в го́род / под крова́ть / за шкаф / за стол — all accusative, because every verb is motion-to; в гости́нице — prepositional, because останови́лся here marks staying/location)
The dedicated в/на page is в and на: in/on vs into/onto; the location forms in depth are on prepositional location with в/на; and за/под as instrumental-location prepositions are on instrumental prepositions.
Common Mistakes
❌ Я иду́ в шко́ле.
Incorrect — 'going to school' is motion, so в needs the accusative: шко́ле → шко́лу. The prepositional шко́ле means being AT school.
✅ Я иду́ в шко́лу.
I'm going to school. (в + accusative шко́лу = motion-to)
❌ Кни́га лежи́т на стол.
Incorrect — лежи́т is a position verb (location), so на takes the prepositional: стол → столе́. The accusative стол would mean motion 'onto.'
✅ Кни́га лежи́т на столе́.
The book is lying on the table. (на + prepositional столе́ = location)
❌ Кот сиди́т за дива́н.
Incorrect — сиди́т is static, so за takes the instrumental: дива́н → дива́ном. The accusative дива́н would mean motion 'to behind.'
✅ Кот сиди́т за дива́ном.
The cat is sitting behind the sofa. (за + instrumental дива́ном = location)
❌ Положи́ су́мку под столо́м.
Incorrect — положи́ is a putting/motion verb, so под takes the accusative: столо́м → стол. The instrumental столо́м would mean static 'under.'
✅ Положи́ су́мку под стол.
Put the bag under the table. (под + accusative стол = motion-to)
❌ Я верну́лся в шко́лы.
Wrong direction — coming 'from school' uses из + genitive: из шко́лы; you can't use в for 'from.' (в шко́лы isn't even a valid singular form.)
✅ Я верну́лся из шко́лы.
I came back from school. (из + genitive шко́лы)
Key Takeaways
- в, на, за, под each take two cases, and the case answers куда? (motion) vs где? (location).
- Motion-to is always the accusative for all four (в шко́лу, на рабо́ту, за стол, под стол).
- Location splits: в/на take the prepositional (в шко́ле, на рабо́те); за/под take the instrumental (за столо́м, под столо́м).
- The verb picks the case: movement verbs (идти́, класть, сади́ться) → accusative; state verbs (быть, лежа́ть, сиде́ть) → location case.
- The full spatial triangle adds "from": из / с + genitive (в→из, на→с), giving each place three forms — to, at, from.

- В and На: In/On vs Into/OntoA1 — The two workhorse prepositions в (in/into) and на (on/onto) each take TWO cases: the accusative for motion toward a place (Я иду́ в шко́лу, на рабо́ту) and the prepositional for static location (Я в шко́ле, на рабо́те). The case carries the direction-vs-location meaning. Choosing в vs на itself is lexical — в for enclosed spaces, на for surfaces, events, and a fixed memorized list. Plus the matching 'from' words: в↔из, на↔с.
- Instrumental Prepositions: с, над, под, перед, междуA2 — Five prepositions take the instrumental: с/со ('with'), над ('above'), под ('under' — location), пе́ред ('in front of, before'), and ме́жду ('between'). За + instrumental ('behind, at') and ря́дом с ('next to') belong here too. The key contrast: за and под mean LOCATION with the instrumental but MOTION with the accusative.
- Prepositions and Case: How They Work TogetherA1 — The single biggest idea about Russian prepositions: every preposition GOVERNS a case — it is never used alone, and you cannot choose a preposition without also choosing the case it demands. A map of the system by case (genitive: из, от, до, у, для, без, о́коло; dative: к, по; accusative: в, на, за, под, че́рез; instrumental: с, над, под, пе́ред, ме́жду; prepositional: о, при, в/на for location), plus the two-case prepositions where the case itself carries the meaning.
- The Many Uses of С/СоB1 — The preposition с is a two-case workhorse, and the case alone decides the meaning. With the GENITIVE it means 'from / off' a surface and 'since' a point in time (с рабо́ты, с по́лки, с понеде́льника). With the INSTRUMENTAL it means 'with / together with' and 'having' (с дру́гом, ко́фе с молоко́м, челове́к с ю́мором). Flip the case, flip the meaning. The form со appears before awkward consonant clusters (со мной, со стола́), and с + genitive is the mirror of на + accusative in the из/с 'from' system.
- 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.
- Accusative After Prepositions (в, на, за, под, через, про)A2 — The accusative is the case of DESTINATION and DURATION after prepositions: в/на/за/под switch to the accusative the moment there is motion toward a place (иду́ в шко́лу, кладу́ под стол), paired against their prepositional/instrumental location forms (я в шко́ле); plus through/across/in-a-time че́рез + acc (че́рез мост, че́рез час), the barrier-piercing сквозь, the colloquial 'about' про, and о/об in the sense of 'against' (уда́риться о ка́мень).
