Prepositions with the Genitive: do, z, od, bez, u

The genitive governs more prepositions than any other Czech case, and five of them are so common that you cannot get through a single conversation without them: do, z/ze, od/ode, bez/beze, u. They cover going into places, coming out of them, receiving things from people, doing without something, and being at someone's home. Each of these forces its noun into the genitive, so before anything else, fix this in your mind: after these five words, the noun is genitive, every single time.

Where this gets interesting — and where English speakers stumble — is that Czech splits up meanings that English lumps together. English has one word to and one word from; Czech makes you choose, and the choice depends on whether you are dealing with an enclosed space, a surface, or a person.

do — into / to (entering an enclosed space)

do means motion into something you can be inside of: a building, a city, a country, a room, a bag. Think of it as "to, with arrival inside."

Because do is about entering, it pairs naturally with its opposite, z (coming back out). Czech speakers feel do and z as a matched pair the way English feels in and out.

z / ze — out of / from (exiting an enclosed space)

z means motion out of the same kind of enclosed space that do takes you into. It is the natural answer to "where did you come from?" when the answer is a place you were inside. The form is ze before awkward consonant clusters (ze školy, ze dřeva).

od / ode — away from a person or a starting point

Here is the distinction that trips up almost every English speaker. z gets you out of an enclosed space; od gets you away from a person, or marks a starting point (in space, time, or origin of a gift or message). You leave a building with z, but you leave a person with od.

That last example shows the elegant od … do frame: a span from a starting point (od) to an end point (do), both with the genitive. Use it for working hours, opening times, and any range.

The 'to' and 'from' splits, side by side

English to and from each cover two Czech prepositions. This is the single biggest source of error, so here it is laid out plainly:

So I'm going to the doctor (approaching the person) is jdu k lékaři (k + dative), but I'm coming from the doctor (leaving that person) is jdu od lékaře (od + genitive). The full do vs. k contrast has its own page; the key for now is that do is not the all-purpose "to."

bez / beze — without

bez means without, and it is wonderfully consistent: whatever follows goes into the genitive, no exceptions. The longer form beze appears before tricky clusters (beze mě, beze slov).

Watch the ending closely: it is bez cukru, not bez cukr. English keeps the noun bare after without, so the missing -u is exactly the kind of error you will make until the genitive becomes reflex.

u — at the place of / by

u means at or by in the sense of being at someone's place or right next to something. It is the word for being at the doctor's, at Grandma's, at home with the family — and also for being physically beside something (u okna, by the window).

Note the three-way logic with people and the doctor: you go to the doctor with k (k lékaři), you are at the doctor's with u (u lékaře), and you come from the doctor with od (od lékaře). Same person, three prepositions — and u and od both take the genitive, so the noun looks identical (lékaře); only k switches to the dative (lékaři).

Common Mistakes

Key Takeaways

• do, z/ze, od/ode, bez/beze, u all govern the genitive — every time.
• do (into) ↔ z (out of) for enclosed spaces; k (to a person) ↔ od (from a person).
• u = at someone's place / beside something; with people it sits between k (going to) and od (coming from).
• The genitive ending is not optional padding — bez cukru, not bez cukr. Drop it and the sentence is wrong.
