When you want to say I'm in / at a place or I'm going to a place, Czech makes you choose between two prepositions, v and na. About four-fifths of the time the choice follows a simple rule of meaning; the rest is a short list you memorize. This page is the decision tool — a flowchart that gets you to the right preposition fast, plus the exception list you must commit to memory. For the systematic write-up and the full exception tables, see the reference page on v versus na.
The one-line answer
Ask: am I inside an enclosed space? If yes, use v. If it is a surface, an open area, an event, an island, or one of the memorized exceptions, use na.
The decision tree
Run a place through these questions in order and stop at the first "yes".
Step 1 — Is it on my memorized na-list? If the place is a Slovakia-type country/region or a post-office-type institution (full list below), it takes na, no matter how enclosed it is. Stop here.
Step 2 — Is it an event or activity rather than a building? A concert, a wedding, a meeting, a trip, an exhibition — anything you attend or do — takes na. Stop here.
Step 3 — Is it a surface, an island, or an open area? On top of something (roof, table, square), out in the open (field, mountain), or an island takes na. Stop here.
Step 4 — Otherwise: it's an enclosed interior → use v. Houses, flats, towns, the bank, the cinema, the shop, the forest, most countries — all v.
Step 1 in practice: the memorize-list
These do not follow the meaning rule. Learn them as raw vocabulary.
| na (memorize) | What it covers |
|---|---|
| na Slovensku, na Ukrajině, na Moravě | countries / regions (vs v Čechách, v Německu) |
| na Islandu, na Maltě, na Kypru | islands |
| na poště | post office |
| na nádraží | train station |
| na úřadě | government office |
| na univerzitě / na fakultě | university / faculty |
| na hradě, na zámku | castle, chateau |
| na vesnici | in the village / countryside |
The most useful contrast to drill is the Czech-lands pair: v Čechách (Bohemia) but na Moravě (Moravia). They are neighbouring regions yet take different prepositions, which is exactly why this is a favourite exam trap.
V Čechách bydlí teta, na Moravě strýc.
My aunt lives in Bohemia, my uncle in Moravia.
Celé léto jsem strávil na Slovensku u babičky.
I spent the whole summer in Slovakia at my grandmother's.
Musíš zajít na úřad a vyřídit to osobně.
You have to go to the government office and sort it out in person.
Steps 2–4 in practice
Once the memorize-list is out of the way, the meaning rule handles the rest.
Events / activities → na:
Včera jsme byli na koncertě a dnes jdeme na výstavu.
Yesterday we were at a concert and today we're going to an exhibition.
Seznámili se na svatbě společného kamaráda.
They met at a mutual friend's wedding.
Surfaces / open areas / islands → na:
Knihy nech na stole a boty nech na chodbě.
Leave the books on the table and the shoes in the hallway.
Na náměstí stál velký vánoční strom.
A big Christmas tree stood on the square.
Enclosed interiors → v:
Pracuju v bance, manželka učí v nemocnici.
I work at a bank, my wife teaches at a hospital.
Bydlíme v Praze, ale narodili jsme se v Ostravě.
We live in Prague, but we were born in Ostrava.
Schovali jsme se před deštěm v lese.
We took shelter from the rain in the forest.
Notice how the rule sorts side-by-side options: a bank is an interior you enter (v bance), but a post office — physically identical — is on the memorized na-list (na poště). The flowchart catches that because Step 1 runs before the meaning rule.
Matching the destination form
Choosing the preposition is only half the job. As soon as you describe motion toward the place rather than being at it, the case changes — and the v-places and na-places diverge:
- v-place → do + genitive for "to": do banky, do Prahy, do lesa, do Itálie.
- na-place → na + accusative for "to": na poštu, na koncert, na Slovensko, na Moravu.
So learn every place as a pair: the where form and the where to form.
| Where? (locative) | Where to? (destination) |
|---|---|
| v bance | do banky |
| v Praze | do Prahy |
| na poště | na poštu |
| na koncertě | na koncert |
| na Slovensku | na Slovensko |
Nejdřív jdu do banky a pak na poštu.
First I'm going to the bank, then to the post office.
Jedeme do Prahy a odtud pak na Moravu.
We're driving to Prague and from there on to Moravia.
A handy memory hook: the preposition that means "in/at" tells you which "to" preposition you need. If the place lives with v, its destination uses do; if it lives with na, its destination stays na. For the genitive endings on the do-forms, see Prepositions with the Genitive: do, z, od, bez, u; for getting around in general, see Directions and Transport.
A note for English speakers
English uses in, at, and to without any of these splits — at the bank, at the post office, at the station all sound the same — so there is no English cue that bank should behave differently from post office. That means you cannot derive the Czech preposition from the English one. Run the flowchart instead, and when a place lands on the na-list, store the whole Czech phrase (na poště, na nádraží) as a single unit so the preposition comes back automatically.
Common Mistakes
1. Choosing v for a memorized na-institution.
❌ Čekám na tebe v nádraží.
Incorrect — the station is on the na-list: na nádraží.
✅ Čekám na tebe na nádraží.
I'm waiting for you at the station.
2. Applying the in/at logic of English to a region.
❌ Mám kamarády v Ukrajině.
Incorrect — Ukraine takes na: na Ukrajině.
✅ Mám kamarády na Ukrajině.
I have friends in Ukraine.
3. Mismatching the destination preposition. A v-place must take do, not na, for motion.
❌ Po práci jdu na banku.
Incorrect — the bank is a v-place, so motion uses do: do banky.
✅ Po práci jdu do banky.
After work I'm going to the bank.
4. Keeping the locative when you mean motion.
❌ V sobotu jedeme na Slovensku.
Incorrect — motion toward needs the accusative: na Slovensko.
✅ V sobotu jedeme na Slovensko.
On Saturday we're driving to Slovakia.
