Imperative for ty/my/vy from the 3rd person plural stem, negative commands with the imperfective, and aspect choice in orders
I can give instructions, invitations and prohibitions with correct imperative forms and aspect.
Look at these examples. Can you spot the grammar pattern?
Kup cestou dvě piva a nezapomeň na chleba!
Buy two beers on the way and don't forget the bread!
Pojďme v sobotu na Vyšehrad, vezměte i děti!
Let's go to Vyšehrad on Saturday — bring the kids too!
Nebojte se mluvit česky, nikdo se vám smát nebude.
Don't be afraid to speak Czech — nobody will laugh at you.
Pay attention to the highlighted parts. What do they have in common?
English makes a command from the bare verb: Sit! Write! Czech builds it from the "they" form of the present tense (oni), and has three forms: for ty, for my (let's) and for vy.
Take the oni form and remove the ending. If the stem ends in one consonant, that is the ty form; add -me and -te for the others. If it ends in two consonants, add -i, and -ěme/-ěte (spelled -eme/-ete after l: mysli, myslete).
| Infinitive | oni | ty | my | vy |
|---|---|---|---|---|
| dělat | dělají | dělej | dělejme | dělejte |
| psát | píšou | piš | pišme | pište |
| koupit | koupí | kup | kupme | kupte |
| číst | čtou | čti | čtěme | čtěte |
| říct | řeknou | řekni | řekněme | řekněte |
Two small adjustments: -aj- becomes -ej- (dělají → dělej), and a long vowel often shortens (píšou → piš, koupí → kup). Learn the irregulars as words: buď (být), měj (mít), jez (jíst), jdi (jít), pojď (come), pomoz (pomoct), vezmi, colloquially vem (vzít).
English speakers tend to negate whatever verb they learned first, and produce *Nekup to. Ask yourself whether you are forbidding (imperfective) or warning (perfective).
The my form is English "let's": Pojďme v sobotu na Vyšehrad. For "let him / may it" Czech uses ať + present: Ať zavolá zítra. Ať žijí novomanželé! On signs and in curt orders you will meet the infinitive: Nekouřit. Nevstupovat. It is correct, but it sounds like a notice, not a person.
The most famous Czech imperative is heard thousands of times a day in the Prague metro: Ukončete, prosím, výstup a nástup, dveře se zavírají. The vy form with prosím is the polite default with anyone you do not know.
