Russian Prefixes

Prefixes

Russian builds an enormous number of verbs by gluing a small prefix (приста́вка) onto a root verb. A prefix does two jobs at once: it usually turns the verb perfective (see verb aspects), and it changes the meaning — often in a systematic, predictable way. Learn the handful of common prefixes and their core senses, and dozens of new verbs suddenly start to make sense.

One root, many verbs

Take the root писа́ть (to write). Each prefix bends the meaning in a different direction:

Verb	Meaning
написа́ть	write / finish writing (the plain perfective)
переписа́ть	rewrite / copy out
подписа́ть	sign (write under)
записа́ть	write down / record
вы́писать	write out / discharge (e.g. from hospital)
описа́ть	describe (write around)
расписа́ться	sign one’s name / register a marriage

Notice that the core idea of “writing” stays, while the prefix adds a direction, a completion, or a nuance. This is the pattern behind most of the Russian vocabulary you will meet.

The most common prefixes

Each prefix has a core sense that shows up again and again. Here are the ones to know first:

Prefix	Core meaning	Example
по-	a bit / start of an action	поговори́ть (talk a while)
при-	arrival / towards / attaching	прийти́ (arrive)
у-	away / off	уйти́ (leave)
вы-	out	вы́йти (exit)
в(о)-	in / into	войти́ (enter)
от(о)-	away from / detach	отойти́ (step away)
до-	up to / reach a point	дойти́ (reach on foot)
за-	begin / drop by / behind	заговори́ть (start talking)
пере-	across / re- (again)	перейти́ (cross)
про-	through / past	пройти́ (pass through)
раз-/рас-	apart / un-	разби́ть (smash apart)
с(о)-	together / down / off	сде́лать (do / complete)
об-/о-	around / about	описа́ть (describe)
под-	up to / under	подойти́ (approach)

Meanings are a guide, not a formula: the prefix often adds a figurative twist (по- in поня́ть = “understand” is not literally “a bit”). But the core sense is a reliable first bet.

Directional prefixes with motion verbs

Prefixes are clearest with verbs of motion like идти́ (go on foot) and е́хать (go by vehicle). Here the prefix simply tells you the direction:

Verb	Prefix sense	Meaning
прийти́	при- towards	arrive
уйти́	у- away	leave
войти́	в- in	enter
вы́йти	вы- out	exit
дойти́	до- up to	reach
перейти́	пере- across	cross
подойти́	под- up to	approach
отойти́	от- away from	step away

Some examples in sentences:

По́езд пришёл во́время. (The train arrived on time.)
Он вы́шел из ко́мнаты. (He left the room.)
Мы перешли́ у́лицу. (We crossed the street.)
Официа́нт подошёл к столу́. (The waiter came up to the table.)

при- vs пре-

These two sound almost identical when unstressed, but they mean different things:

при- = approaching, a little, or attaching — прийти́ (arrive), приши́ть (sew on), приоткры́ть (open slightly).
пре- = very / over, like пере- — превы́сить (exceed), преувели́чить (exaggerate), прекра́сный (splendid, “very beautiful”).

A useful test: if you can replace it with “very” or пере-, it is пре-. If it is about coming closer or a small degree, it is при-.

Spelling: з or с?

A few prefixes ending in з change their final consonant depending on the sound that follows. This affects раз-/рас-, из-/ис- and без-/бес-:

Before a voiced consonant, keep з: разби́ть (smash apart), изгна́ть (banish), безду́мный (thoughtless).
Before a voiceless consonant, write с: расписа́ть (paint / paint over), испо́ртить (spoil), бесполе́зный (useless).

Compare the pair directly: разби́ть (б is voiced → з) vs расписа́ть (п is voiceless → с). You spell it the way it is pronounced.

The prefix с- is different: it is always written с, even before voiced sounds — сде́лать, сда́ть — although it is pronounced “z” there.

Common mistakes

Assuming the prefix meaning is always literal. Many prefixed verbs are idiomatic — check the dictionary sense.
поня́ть (understand) is not “to a bit”.
Forgetting the prefix makes the verb perfective.
Я написа́ть письмо́. (wrong) → Я напишу́ письмо́. (I’ll write the letter — perfective future)
Spelling рас-/раз- by the root, not the sound.
разписа́ть (wrong) → расписа́ть (correct — before voiceless п)
Confusing при- and пре-.
приувели́чить (wrong) → преувели́чить (exaggerate)

Summary

A prefix usually makes a verb perfective and adds meaning at the same time.
One root can spawn many verbs: писа́ть → написа́ть, переписа́ть, подписа́ть, записа́ть, описа́ть…
Each prefix has a core sense (вы- out, при- towards, у- away, пере- across / re-) — clearest with motion verbs.
при- = approaching / a little; пре- = very / over (like пере-).
раз-/из-/без- keep з before voiced sounds, become с before voiceless ones.
