brát / vzít ("to take") is the most famous irregular verb pair in Czech, and the reason is worth understanding from the start: the two members come from completely different roots. brát (imperfective) and vzít (perfective) are not two forms of one word the way dělat and udělat are — they are two separate verbs that the language has yoked together to serve as a single aspect pair. Linguists call this suppletion, and brát/vzít is the standard textbook example of it in Czech, exactly as English "go / went" is for tense.
Suppletion: why two roots?
Most Czech aspect pairs share a stem and differ only by a prefix or suffix (dělat → udělat, psát → napsat). brát/vzít does not. There is no orthographic bridge between br- and vz-; you simply have to learn both and know that they pair up. This is not a regularity you can derive — it is a fact about the lexicon.
| Imperfective | Perfective | |
|---|---|---|
| Infinitive | brát | vzít |
| Present stem | ber- | vezm- |
| Past (m.) | bral | vzal |
Beru léky každé ráno.
I take medicine every morning. (habitual — imperfective brát)
Vezmu si jen tohle a jdeme.
I'll just take this and we'll go. (single action — perfective vzít)
For why pairs exist at all, see what is aspect and the aspect pairs overview.
Present tense — brát (imperfective)
The infinitive is brát, but the present stem is ber- — the r of the root surfaces with an e before the endings. This belongs to the -e- conjugation class (the nese / bere type). Describes taking as a habit, a repeated action, or a process.
| Person | Form | Meaning |
|---|---|---|
| já | beru | I take / I'm taking |
| ty | bereš | you take |
| on / ona / ono | bere | he / she / it takes |
| my | bereme | we take |
| vy | berete | you take |
| oni / ony / ona | berou | they take |
Bereš si cukr do kávy?
Do you take sugar in your coffee?
V práci nás neberou vážně.
At work they don't take us seriously.
See the present paradigm of this class at class -e- (nese / bere).
Present-future of vzít (perfective)
vzít is perfective, so its present-form endings express the future — a single completed taking. The present stem is vezm-, again unrelated to the infinitive shape vzít.
| Person | Form | Meaning (future) |
|---|---|---|
| já | vezmu | I'll take |
| ty | vezmeš | you'll take |
| on / ona / ono | vezme | he / she / it will take |
| my | vezmeme | we'll take |
| vy | vezmete | you'll take |
| oni / ony / ona | vezmou | they'll take |
Vezmu tě do práce autem.
I'll take you to work by car.
Vezmeme to nejkratší cestou.
We'll take the shortest way.
Past tense
Both members form the past from an l-participle plus the být auxiliary in the first and second persons, with gender agreement. The imperfective participle is bral; the perfective is vzal (with the feminine vzala and masculine-animate plural vzali). See forming the past tense.
| Subject | brát (imperfective) | vzít (perfective) |
|---|---|---|
| já (m.) | bral jsem | vzal jsem |
| já (f.) | brala jsem | vzala jsem |
| on | bral | vzal |
| ona | brala | vzala |
| ono | bralo | vzalo |
| my (m. anim.) | brali jsme | vzali jsme |
| my (f.) | braly jsme | vzaly jsme |
Bral jsem ty léky tři měsíce.
I took those pills for three months. (duration — imperfective, male speaker)
Vzala si dovolenou a odjela k moři.
She took time off and went to the seaside. (completed — female subject)
The suppletion, side by side
Seeing all the forms in one frame makes the two-root structure unmistakable: nothing in the left column shares material with the right.
| Form | Imperfective (brát) | Perfective (vzít) |
|---|---|---|
| infinitive | brát | vzít |
| present (já) | beru | vezmu (future) |
| past (m.) | bral | vzal |
| imperative (ty) | ber | vezmi |
Normálně beru autobus, ale dnes vezmu taxíka.
I normally take the bus, but today I'll take a taxi. (habit = brát, one occasion = vzít — both in one sentence)
Imperative
The imperatives, too, are built on the separate stems: ber from ber-, vezmi from vezm-.
| Person | brát | vzít |
|---|---|---|
| ty | ber | vezmi |
| my | berme | vezměme |
| vy | berte | vezměte |
Vezmi si deštník, prší.
Take an umbrella, it's raining. (one specific action — perfective)
Neber si to tak!
Don't take it so hard! (negative commands prefer the imperfective)
Government and the reflexive vzít si / brát si
Both members take a direct object in the accusative (accusative verbs). Extremely common is the reflexive vzít si / brát si with the dative reflexive si, "to take for oneself" — to help oneself to something, to pick one up, to take it along.
Vezmu si to.
I'll take it. / I'll have this one. (to = accusative; si = 'for myself')
Berte si, je toho dost!
Help yourselves, there's plenty! (at the table)
Vzali se loni v létě.
They got married last summer. (vzít se = to marry, an idiom literally 'to take each other')
Common mistakes
❌ Budu vzít taxíka.
Wrong — budu never combines with a perfective infinitive like vzít.
✅ Vezmu si taxíka. / Budu brát taxíka.
I'll take a taxi. / I'll be taking a taxi (regularly).
❌ Vzeju si to. / Bru si to.
Wrong stems — the present forms are vezmu (perfective) and beru (imperfective).
✅ Vezmu si to. / Beru si to.
I'll take it. / I take it (habitually).
❌ Každé ráno vezmu léky.
Wrong aspect — a daily habit is imperfective.
✅ Každé ráno beru léky.
Every morning I take medicine.
❌ Ber si deštník, prší.
Odd — a one-off command here should be perfective.
✅ Vezmi si deštník, prší.
Take an umbrella, it's raining.
