After arrival and departure (при-/у-), the next pair to master concerns the threshold: stepping into an enclosed space and stepping out of it. В-/во- means "go in, enter"; вы- means "go out, exit." Where при-/у- describe the whole journey to or from a place, в-/вы- zoom in on the single act of crossing the boundary — through a door, a gate, a room. This page also carries one of the most important pronunciation facts in the entire motion system: the stress behaviour of вы-.
В-/ВО-: enter, go in
The prefix в- (spelled во- before a consonant cluster, for ease of pronunciation) means motion into an enclosed or bounded space:
- войти́ (pf, on foot) / входи́ть (impf) — to enter, come/go in (walking)
- въе́хать (pf, by vehicle) / въезжа́ть (impf) — to drive in, enter (riding)
войти́ takes the fill vowel -о- before the cluster -йти́ (во + йти → войти́), and its future is built on -йд-: войду́, войдёшь, войду́т; past вошёл / вошла́ / вошли́.
Войди́те, пожа́луйста, дверь откры́та.
Come in, please, the door is open. (imperative of войти́)
Он вошёл в ко́мнату и включи́л свет.
He came into the room and switched on the light. (вошёл в + acc)
Маши́на ме́дленно въе́хала во двор.
The car slowly drove into the courtyard. (въе́хать; во двор with the fill vowel)
The preposition: в / на + accusative
В- pairs with the direction-into prepositions, in the accusative:
- в + accusative for entering something you can be inside of: в ко́мнату, в зда́ние, в авто́бус
- на + accusative for the minority of places that take на: на сце́ну (onto the stage), на ста́нцию
По́езд въе́хал на ста́нцию ро́вно по расписа́нию.
The train pulled into the station exactly on schedule. (на ста́нцию takes на + acc)
Когда́ вхо́дишь в зда́ние, нужно́ показа́ть про́пуск.
When you enter the building you have to show your pass. (входи́ть в + acc, habitual)
ВЫ-: exit, go out — and "step out for a moment"
The prefix вы- means motion out of an enclosed space:
- вы́йти (pf, on foot) / выходи́ть (impf) — to go out, exit, leave (walking)
- вы́ехать (pf, by vehicle) / выезжа́ть (impf) — to drive out, set off (riding)
вы́йти builds its future on -йд-: вы́йду, вы́йдешь, вы́йдут; past вы́шел / вы́шла / вы́шли. Note the stress on the prefix throughout — more on that below.
Beyond literal exit, вы́йти carries an everyday meaning English splits off into a separate phrase: "to step out for a moment, to be briefly unavailable." «Он вы́шел» on the phone or at the office means "he's stepped out," not "he's left for good" — the implication is that he'll be back shortly. This is the normal, idiomatic way to say someone is momentarily away from their desk.
Она́ вы́шла из ко́мнаты, не сказа́в ни сло́ва.
She went out of the room without a word. (вы́шла из + gen)
— Мо́жно Ива́на Петро́вича? — Он вы́шел, перезвони́те че́рез час.
— May I speak to Ivan Petrovich? — He's stepped out, call back in an hour. (idiomatic вы́шел = 'briefly away')
Нам пора́, дава́й вы́едем пора́ньше, что́бы не попа́сть в про́бку.
It's time to go, let's set off a bit early to avoid the traffic. (вы́ехать = set off / drive out)
The preposition: из / с + genitive
ВЫ- pairs with source prepositions in the genitive, mirroring exactly the destination prepositions of в-:
- из + genitive out of what you'd enter with в: из ко́мнаты, из зда́ния
- с + genitive off what you'd reach with на: со сце́ны (off the stage), с рабо́ты
Арти́сты вы́шли со сце́ны под аплодисме́нты.
The performers came off the stage to applause. (на сце́ну → со сце́ны)
The stress rule you must not miss
Here is the fact that trips up nearly every learner. The prefix вы- is always stressed in the perfective, and never stressed in the imperfective:
| Perfective (вы- stressed) | Imperfective (вы- unstressed) | |
|---|---|---|
| on foot | вы́йти, вы́йду, вы́шел | выходи́ть, выхожу́, выходи́л |
| by vehicle | вы́ехать, вы́еду, вы́ехал | выезжа́ть, выезжа́ю, выезжа́л |
Russian stress is otherwise mobile and hard to predict, so a prefix that always grabs the stress is a gift — but only the perfective. As soon as you switch to the imperfective, the stress jumps off вы- and onto the ending. There is no logical reason for this; it is a fixed property of the prefix вы- specifically (other prefixes never behave this way). You simply memorise it. The general unpredictability of Russian stress and how prefixes interact with it is treated on stress shift with prepositions.
Я вы́йду на сле́дующей остано́вке.
I'll get off at the next stop. (perfective → вы́йду, stress on the prefix)
Я выхожу́ здесь ка́ждое у́тро.
I get off here every morning. (imperfective → выхожу́, stress on the ending)
В-/вы- versus при-/у-: threshold vs whole journey
Both pairs are about coming and going, so when do you use which? The difference is scope:
- при-/у- describe arrival at, or departure from, a place as a whole — the destination or origin of a trip. Он прие́хал в Москву́ = the whole journey to Moscow is done.
- в-/вы- describe the single act of crossing a boundary — going through a doorway, entering or leaving an enclosed space. Он вошёл в ко́мнату = he crossed the threshold of the room.
You arrive in town (прие́хать), then you enter the building (войти́). You finish your meeting and exit the office (вы́йти), then you leave the city (уе́хать).
Мы прие́хали в Москву́, нашли́ оте́ль и вошли́ в но́мер.
We arrived in Moscow, found the hotel, and went into the room. (прие́хать = whole trip; войти́ = crossing the room's threshold)
Common Mistakes
❌ Я выйду́ на сле́дующей остано́вке.
Stress error — the perfective with вы- is stressed on the prefix: вы́йду, not *выйду́.
✅ Я вы́йду на сле́дующей остано́вке.
I'll get off at the next stop. (perfective вы- is stressed → вы́йду)
❌ Он вы́ходит из ко́мнаты ка́ждое у́тро.
Stress error — the imperfective does NOT stress вы-; the stress falls on the stem: выхо́дит, never *вы́ходит.
✅ Он выхо́дит из ко́мнаты ка́ждое у́тро.
He leaves the room every morning. (imperfective → stress off the prefix: выхо́дит)
❌ Он вошёл из ко́мнаты.
Wrong direction — в- means INTO; coming OUT of the room needs вы́шел из ко́мнаты.
✅ Он вы́шел из ко́мнаты.
He went out of the room. (exit → вы́йти + из + gen)
❌ Он вошёл в ко́мнаты.
Case error — direction-into takes the accusative singular в ко́мнату, not the genitive/plural ко́мнаты.
✅ Он вошёл в ко́мнату.
He came into the room. (в + accusative for entering)
❌ — Мо́жно дире́ктора? — Он ушёл. (когда́ он то́лько отлучи́лся)
Overstated absence — if he's only stepped out briefly, ушёл ('he's left/gone') sounds permanent; вы́шел signals he'll be back.
✅ Он вы́шел, перезвони́те че́рез полчаса́.
He's stepped out, call back in half an hour. (вы́шел = momentarily away)
Key Takeaways
- В-/во- = enter, go in (войти́/входи́ть, въе́хать/въезжа́ть) + в/на + accusative. The fill vowel -о- appears before clusters: войти́, во двор.
- Вы- = exit, go out (вы́йти/выходи́ть, вы́ехать/выезжа́ть) + из/с + genitive. The в↔из and на↔с symmetry is exact.
- Вы- is always stressed in the perfective (вы́йти, вы́шел, вы́еду) and never in the imperfective (выходи́ть, выхо́дит, выезжа́ть). No exceptions.
- Вы́йти also means "step out for a moment / be briefly unavailable" — «Он вы́шел» = he'll be back, not he's gone for good.
- В-/вы- focus on crossing a threshold; при-/у- describe the whole journey to or from a place. You arrive in town (прие́хать), then enter the building (войти́).

- Prefixed Verbs of Motion: How the System WorksB1 — The second half of the motion system. Adding a directional prefix (при-, у-, в-, вы-, под-, от-, до-, пере-, про-, за-, об-) does two things at once: it specifies a spatial direction AND converts the verb into an ordinary aspect pair. Prefix + UNIDIRECTIONAL stem = PERFECTIVE (прийти́ 'arrive'); prefix + MULTIDIRECTIONAL stem = its IMPERFECTIVE partner (приходи́ть). The unidirectional/multidirectional contrast is replaced by perfective/imperfective — the structural pivot that makes the whole prefixed system tractable.
- Motion Prefixes: При- (Arrive) and У- (Leave)B1 — The first and most frequent pair of directional prefixes. ПРИ- marks arrival — motion that ends at a destination, so the subject is now here (Он прие́хал в Москву́). У- marks departure into absence — the subject is now gone (Она́ уе́хала в Москву́). Each builds an ordinary aspect pair (прийти́/приходи́ть, уйти́/уходи́ть) and pairs with its own prepositions: при- with destinations (в/на + acc, к + dat), у- with sources (из/с + gen, от + dat-person).
- Motion Prefixes: Под- (Approach), От- (Move Off), До- (Reach)B1 — The proximity prefixes. ПОД-/ПОДО- means approach, come up to (подойти́/подходи́ть + к + dat); ОТ-/ОТО- means move off, step away from (отойти́/отходи́ть + от + gen); ДО- means reach, get as far as (дойти́/доходи́ть + до + gen). Под- and от- are short-range — toward a point and away from it — while до- emphasises reaching the endpoint. Each prefix is reinforced by a fixed preposition that echoes it: подойти́ К, отойти́ ОТ, дойти́ ДО.
- Verbal Aspect: The Big PictureA2 — Aspect is the spine of the Russian verb: nearly every verb belongs to a pair — imperfective (process, repetition, general fact) and perfective (a single completed whole with a result). This page explains the pair, the consequences for the tense system (perfectives have no present), and why you must decide 'process or result?' before you even pick a tense.
- 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.
- Stress Retraction onto PrepositionsC1 — In a closed set of fixed preposition+noun phrases, the stress jumps backwards off the noun and onto the normally-toneless preposition (на́ берег, за́ городом, и́з лесу, по́д руку) — a feature of careful, traditional pronunciation that is increasingly optional in casual speech, and that parallels the не́ был / не́ было negation retraction.
