This is where the two great verb systems of Czech meet. You already know the motion pairs — determinate jít vs indeterminate chodit, both imperfective. You also know that prefixes build perfectives. Put a directional prefix on a motion verb and something elegant happens: the determinate/indeterminate distinction dissolves and is replaced by an ordinary perfective/imperfective aspect pair, with the prefix now carrying a precise direction (arrive, leave, enter, cross). The flagship is jít → přijít "to arrive." This page shows the system, so that instead of memorizing dozens of verbs one by one you can read and build them.
The one rule that organizes everything
When you attach a prefix to a motion pair, the two members are reassigned:
- prefix + the determinate verb → the perfective (one completed directed motion).
- prefix + a stem derived from the indeterminate verb → the matching imperfective (the process, or a habit).
So jít (determinate) and chodit (indeterminate) become, under the prefix při- ("arrival"):
| Perfective (from determinate jít) | Imperfective (from indeterminate chodit) | |
|---|---|---|
| arrive (on foot) | přijít | přicházet |
Přijít / přicházet now behaves like udělat / dělat: a clean aspect pair. The determinacy contrast is gone; in its place is the prefix's meaning ("arrival") plus the familiar perfective/imperfective opposition.
Přišel jsem pozdě, omlouvám se.
I arrived late, I'm sorry. (perfective — one completed arrival)
V poslední době přicházím pozdě skoro každý den.
Lately I've been arriving late almost every day. (imperfective — a habit)
Notice the imperfective stem is not chodit itself but a new derived stem -cházet. This is the general rule for jít-based verbs: the perfective is built on -jít and the imperfective on -cházet. The mechanism behind that derivation is the same imperfective-by-suffix process used elsewhere.
The directional prefixes
The reason prefixed motion verbs are worth learning as a system is that the prefixes are highly regular in meaning. Each one adds a direction, and the same prefix means the same thing across jít, jet, nést, and the rest.
| Prefix | Direction | jít (foot) pf. / impf. | jet (vehicle) pf. / impf. |
|---|---|---|---|
| při- | arrive, come (to) | přijít / přicházet | přijet / přijíždět |
| od(e)- | leave, depart (away from) | odejít / odcházet | odjet / odjíždět |
| vy- | out, exit (and: up, on foot) | vyjít / vycházet | vyjet / vyjíždět |
| v(e)- | in, enter | vejít / vcházet | vjet / vjíždět |
| pře- | across, over | přejít / přecházet | přejet / přejíždět |
| do- | reach, get as far as | dojít / docházet | dojet / dojíždět |
| roz(e)- | part, scatter (refl.) | rozejít se / rozcházet se | rozjet se / rozjíždět se |
Note the inserted -e- and -j- that keep the words pronounceable: od- becomes ode- before jít (odejít), v- becomes ve- (vejít), and roz- becomes roze- (rozejít se). For the vehicle verbs the perfective is built on -jet and the imperfective on -jíždět (přijet / přijíždět). These are spelling/euphony rules, not new meanings.
Vlak právě odjíždí z prvního nástupiště.
The train is just leaving from platform one. (imperfective odjíždět)
Autobus už odjel, musíme počkat na další.
The bus has already left, we have to wait for the next one. (perfective odjet)
Opatrně přecházej přes silnici, dívej se na obě strany.
Cross the road carefully, look both ways. (imperfective přecházet, imperative)
The tense twist: prefixed motion verbs lose the present
This is the single most important consequence, and it catches every English speaker. Because the prefixed determinate verb is now perfective, it has no present tense — its present-tense endings carry future meaning, exactly as explained on the perfective present is future.
So přijdu does not mean "I am arriving." It means "I will arrive." To say "I am arriving / I keep arriving," you need the imperfective přicházím.
| Form | Aspect | Meaning |
|---|---|---|
| přijdu | perfective | I will arrive (future) |
| přicházím | imperfective | I am arriving / I keep arriving (present) |
| přišel jsem | perfective | I arrived (past) |
| přicházel jsem | imperfective | I was arriving / I used to come (past) |
Přijdu v osm, počkáš na mě?
I'll come at eight, will you wait for me? (future — perfective přijít)
Hosté přicházejí, postupně se sál plní.
The guests are arriving, the hall is gradually filling up. (present — imperfective přicházet)
Reading the system: prefix + base = meaning
Because both halves are regular, you can decode a prefixed motion verb you have never seen. Take the prefix's direction, add the base verb's manner, and you have the meaning:
- vy- (out) + -jít (foot) → vyjít "to go out / step out" (also "to come up / rise," of the sun).
- do- (reach) + -jet (vehicle) → dojet "to reach (a destination), get there."
- pře- (across) + -jet (vehicle) → přejet "to drive across" — and ominously also "to run over (someone)."
Slunce vyšlo až po deváté, byla mlha.
The sun didn't come up until after nine, it was foggy. (vyjít, of the sun)
Dojeli jsme do Tábora těsně před půlnocí.
We reached Tábor just before midnight. (dojet — reaching the destination)
Vejdi dál, neboj se, pojď do obýváku.
Come on in, don't be shy, come into the living room. (vejít, imperative)
The carry/lead verbs prefix the same way
The pattern is not limited to jít and jet. The transitive motion verbs from nést / nosit prefix identically: the determinate feeds the perfective, the indeterminate feeds the imperfective.
| Base pair | Prefixed perfective | Imperfective | Meaning |
|---|---|---|---|
| nést / nosit | přinést | přinášet | to bring |
| nést / nosit | odnést | odnášet | to take away |
| vést / vodit | přivést | přivádět | to bring (a person) |
| vézt / vozit | přivézt | přivážet | to bring (by vehicle) |
Přines mi prosím deku z ložnice.
Please bring me a blanket from the bedroom. (perfective přinést)
Soused nám každé léto přiváží jablka ze zahrady.
The neighbour brings us apples from his garden every summer. (imperfective přivážet)
Why English speakers stumble here
English packs direction into separate little words after the verb — "come in," "go out," "drive across." Czech packs it into a prefix before the verb, and that prefix simultaneously makes the verb perfective. So an English speaker who says budu přijít is fusing two systems that Czech keeps apart: they are treating přijít as if it were still the imperfective jít that needs budu. It is not — the prefix already perfectivized it. The fix is to internalize that the prefixed "present" přijdu is a future, and that the present/ongoing meaning lives in the -cházet / -jíždět imperfective.
Common Mistakes
❌ Zítra budu přijít v osm.
Incorrect — přijít is perfective; its present-form přijdu already means the future. Never combine budu with a perfective.
✅ Zítra přijdu v osm.
Tomorrow I'll come at eight.
❌ Zrovna přijdu domů, otevři mi.
Incorrect — přijdu is future ('I'll come'); for arriving right now use the imperfective přicházím (or simply jdu domů).
✅ Zrovna přicházím domů, otevři mi.
I'm just arriving home, let me in.
❌ Vlak odjede každých deset minut.
Incorrect — a recurring schedule is imperfective: odjíždí, not the perfective odjede.
✅ Vlak odjíždí každých deset minut.
The train leaves every ten minutes.
❌ Přinášej mi tu knihu, prosím.
Incorrect for a one-off request — that needs the perfective imperative přines, not the imperfective přinášej.
✅ Přines mi tu knihu, prosím.
Bring me that book, please.
❌ Odešel jsem každý večer v deset.
Incorrect — a repeated habit needs the imperfective odcházel, not the perfective odešel.
✅ Odcházel jsem každý večer v deset.
I used to leave every evening at ten.
Key Takeaways
- A directional prefix converts a motion pair into an ordinary perfective/imperfective aspect pair; the determinate/indeterminate contrast disappears.
- Prefix + determinate = perfective (přijít, odjet); prefix + indeterminate-based stem = imperfective (přicházet, odjíždět).
- The prefixes are regular: při- arrive, od- depart, vy- out, v(e)- in, pře- across, do- reach.
- The prefixed perfective has no present: přijdu means "I'll arrive," not "I'm arriving." Never say budu přijít.
- The same system runs through the carry/lead verbs: nést → přinést / přinášet.
