Common Verb Prefixes and Their Meanings | Czech Grammar

Czech builds an enormous part of its vocabulary by gluing a small set of prefixes onto a verb. The same base verb — say psát "to write" — yields napsat, přepsat, opsat, podepsat, vypsat, připsat, dopsat, and a dozen more, each a distinct word with its own dictionary entry. For an English speaker this looks bewildering, but it is also a gift: once you internalize what each prefix tends to mean, you can decode and even guess unfamiliar prefixed verbs on sight. This page is that decoder ring.

How to use this table

Two things make Czech prefixes tricky, and you need to hold both in your head at once.

First, most prefixes carry a spatial or aspectual flavor that recurs across many verbs. Od- means "away," při- means "toward," vy- means "out/up," and so on. These meanings are remarkably consistent for verbs of motion and physical action, which is where you should anchor your intuition.

Second, every prefix also perfectivizes the verb it attaches to. A prefixed verb is almost always perfective. Sometimes the prefix adds only that grammatical completion and nothing semantic — dělat → udělat is just "do" → "get done," same meaning, now bounded. We call that an empty (purely grammatical) prefix. Other times the prefix adds real lexical meaning and perfectivizes at the same time — psát → přepsat "rewrite" is a new word, not just a bounded psát.

💡

The same prefix can be "empty" on one verb and "meaningful" on another. Na- perfectivizes psát into napsat with no added meaning, but it adds "a quantity onto a surface" in nasypat "to pour/heap on." There is no rule that tells you which case you are in — you learn each prefixed verb individually. The table tells you what to suspect.

So treat the meanings below as strong hints, not guarantees. They will let you parse a newspaper verb you have never seen, and they will let you make an educated guess that is right far more often than chance — but you must still confirm each verb's exact sense in a dictionary, because the prefix's literal spatial meaning often shades into something figurative.

The prefix reference table

Prefix	Core meaning(s)	Example pair (impf. → pf.)	Gloss
na-	onto a surface; a quantity of; often purely perfectivizing	psát → napsat	to write (down)
do-	reach/finish, do up to the end	číst → dočíst	to finish reading
pře-	over, across, re- (do again), too much	psát → přepsat	to rewrite
vy-	out, up, out of; thoroughly	jít → vyjít	to go out / come up
za-	begin; behind; cover/shut; momentary	volat → zavolat	to call, give a call
od(e)-	away, off, un- (reverse)	jít → odejít	to leave, go away
při-	toward, arrive, add a bit	jít → přijít	to come, arrive
po-	a bit / for a while; distributive (one after another)	sedět → posedět	to sit a while
pro-	through; thoroughly; spend (time/money)	číst → pročíst	to read through
roz(e)-	apart, in different directions; set in motion	bít → rozbít	to smash, break apart
u-	completion/result; away a little	dělat → udělat	to do (get done)
s(e)-/z-	down; together; off; often purely perfectivizing	jíst → sníst	to eat up
se- (together)	together, converge	jít se → sejít se	to meet up
v(e)-	into, in	jít → vejít	to go into, enter

A note on spelling: several prefixes gain an extra -e- before an awkward consonant cluster, purely for pronounceability — odejít (not odjít), vejít, rozejít se, sejít se. The base prefix is still od-, v-, roz-, s-; the -e- is a fleeting vowel, the same one you meet throughout Czech declension.

One prefix across many verbs

The fastest way to feel the system is to watch a single prefix travel across different bases. Take pře- ("over / across / re-"). Notice how the one core idea — crossing a line, or going over something again — survives in every verb, even as the English translations diverge.

Musím ten dopis přepsat, je v něm moc chyb.

I have to rewrite that letter, it has too many mistakes in it. (pře- = re-, do over)

Přejeli jsme most a hned za ním zabočili doleva.

We drove across the bridge and turned left right after it. (pře- = across)

Přečti si to ještě jednou, než to odešleš.

Read it over one more time before you send it. (pře- = through/over)

Three different verbs — přepsat, přejet, přečíst — and in every one pře- contributes the same "across / over again" core. That is the payoff: meet a fourth one, přeskočit "to jump over / skip," and you can already guess it.

Now compare vy- ("out / up"), which is just as productive:

Vyšel z domu a zamířil k zastávce.

He came out of the house and headed for the stop. (vy- = out)

Slunce vyšlo až po sedmé hodině.

The sun didn't rise until after seven. (vy- = up, out into view)

Vypil celou sklenici vody jedním douškem.

He drank the whole glass of water in one gulp. (vy- = out, to the bottom — thoroughly)

When the prefix is just grammar

Plenty of prefixes add nothing but completion. These are the empty prefixes, and they form the cleanest aspect pairs. The base verb and the prefixed verb mean the same thing; the prefix simply supplies a boundary.

Dělám to každý den, ale dnes to musím udělat rychle.

I do it every day, but today I have to get it done quickly. (u- adds only completion)

Vařila polévku dvě hodiny a nakonec ji uvařila výborně.

She cooked the soup for two hours and in the end cooked it beautifully. (u- adds only completion)

The clue that u- is empty here: udělat still just means "do," uvařit still just means "cook." Contrast that with u- in uletět "to fly away," where it genuinely contributes "away."

Reversal, beginnings, and small amounts

Three flavours deserve a special note because English handles them so differently.

Od- reverses or detaches. Where English often uses "un-" (untie, unscrew) or "off" (take off), Czech reaches for od-: odepnout "unfasten," odšroubovat "unscrew," odejít "leave/go off."

Odepni si pásek, jsme tady.

Unbuckle your belt, we're here. (od- = un-, reverse)

Za- often marks the beginning of an action (an ingressive), as well as "behind / cover / shut." Zazpívat can be "to break into song," zavolat "to give a call," zaplakat "to start crying."

Když uviděla psa, zaštěkal a rozběhl se k ní.

When it saw her, it started barking and ran toward her. (za- = onset; roz- = setting into motion)

Po- means "a little / for a while," or it distributes an action over many objects. Posedět "sit for a bit," popovídat si "have a little chat," but pozavírat "to shut one after another."

Pojď, na chvíli si posedíme a popovídáme.

Come on, let's sit for a bit and have a little chat. (po- = a short while)

Common mistakes

English speakers stumble here in predictable ways. Watch for these.

❌ Musím psát ten dopis dneska.

Incorrect if you mean 'get it written today' — bare psát is the unbounded activity.

✅ Musím napsat ten dopis dneska.

I have to write that letter today. (na- supplies the result/boundary you mean)

❌ Přečtu knihu každý večer.

Incorrect for a habit — the prefixed perfective can't express a repeated routine.

✅ Čtu knihu každý večer.

I read a book every evening. (habits take the bare imperfective)

❌ Odejdu sklenici vody.

Incorrect — od- means 'away/leave', it cannot mean 'drink up'.

✅ Vypiju sklenici vody.

I'll drink up a glass of water. (vy- = out/to the bottom is the right prefix)

❌ Udělal jsem most.

Incorrect if you mean 'drove across the bridge' — u- doesn't mean 'across'.

✅ Přejel jsem most.

I drove across the bridge. (pře- = across)

The deeper lesson: do not translate the English verb plus particle word-by-word. "Read through," "drink up," "go across" are not assembled in Czech the way they are in English. You pick the Czech prefix whose core spatial meaning matches the idea, and that prefix is fused to the verb as a single lexical item.

Key takeaways

Almost every prefixed verb is perfective.
A prefix may add lexical meaning (přepsat "rewrite") or be purely grammatical (udělat "do"); you cannot predict which, so learn each verb.
The spatial/aspectual meanings in the table are strong hints that let you decode and guess unfamiliar verbs — confirm the exact sense in a dictionary.
Anchor your intuition with verbs of motion and physical action, where the prefixes are most literal, then extend to figurative uses.
