Czech Prepositions & Cases
In Czech, a preposition never stands alone — it drags the noun after it into a particular case. That's why Praha becomes do Prahy, v Praze, or z Prahy depending on the little word in front. Learn the preposition together with the case it demands and the endings stop feeling random.
Prepositions Pick a Case
Each preposition has a case it "governs." Here are the ones you'll use first:
| Preposition | Case | Example |
|---|---|---|
| do (into, to) | genitive | do Prahy — to Prague |
| z (from, out of) | genitive | z Prahy — from Prague |
| u (at, by) | genitive | u lékaře — at the doctor's |
| v (in) | locative | v Praze — in Prague |
| na (on, at) | locative / accusative | na náměstí — in the square |
| k (towards, to a person) | dative | k lékaři — to the doctor |
| s (with) | instrumental | s mlékem — with milk |
Location vs. Direction
The single most useful distinction: are you saying where something is, or where it's going? Czech uses different prepositions for each.
| Idea | Preposition + case | Example |
|---|---|---|
| Location (where?) | v + locative | Jsem v Praze. — I'm in Prague. |
| Direction (where to?) | do + genitive | Jedu do Prahy. — I'm going to Prague. |
| From (origin) | z + genitive | Jsem z Prahy. — I'm from Prague. |
Bydlím v Brně, ale zítra jedu do Prahy.
I live in Brno, but tomorrow I'm going to Prague.
Note: v Brně = location (locative); do Prahy = direction (genitive). Same city names, different endings.
The Friendly Pairings
A few preposition-plus-case combinations are worth memorising as fixed units, because they come up in the most ordinary sentences:
| Chunk | English | Case at work |
|---|---|---|
| u mě / u nás | at my place / our place | genitive |
| k lékaři | to the doctor('s) | dative |
| s mlékem | with milk | instrumental |
| z práce | from work | genitive |
Dám si kávu s mlékem.
I'll have a coffee with milk.
Note: s (with) + instrumental: mléko → s mlékem.
v or na?
Both can mean "in/at." The rough rule: v for enclosed spaces you go into, na for surfaces, open places, and events.
| Preposition | Use for | Examples |
|---|---|---|
| v | enclosed places | v bytě (in the flat), ve škole (at school) |
| na | surfaces, open areas, events | na náměstí (in the square), na koncertě (at a concert), na poště (at the post office) |
Hear the anchors in a conversation — tap the speakers:
💬 Meeting at the hospoda
Kde jsi? Čekáme v hospodě.
Where are you? We're waiting in the pub.
Jdu z práce, budu tam za chvíli.
I'm coming from work, I'll be there in a bit.
Sedíme na zahrádce, vedle vchodu.
We're sitting on the terrace, next to the entrance.
Super. Objednej mi jedno pivo!
Great. Order me a beer!
Common Mistakes
- Same ending for motion and location. Bydlím do Prahy mixes the systems. Going = do Prahy (genitive); being there = v Praze (locative).
- Using v for the na-words. Post office, square, concert, mountains — na poště, na náměstí, na koncertě, na horách. They're a memorised club, not a logical one.
- Adding s to transport. By train is bare instrumental: vlakem, not s vlakem (that would mean keeping the train company).
- Translating "to" always as do. Events and open places take na + accusative: na koncert, na oběd, na poštu.
- Learning cases as tables first. Learn the anchor phrases instead — do Prahy, v Praze, s mlékem, bez cukru — and let the endings generalise from there.
What You Can Do Now
You can say where you're going, where you are, where you're from, who you're with, and what you want your coffee without — the prepositional skeleton of daily Czech. That completes the case-system unit. Finish the path with verbal aspect — the last big idea of beginner Czech.
