Polish Cases Made Simple: Ending Tables, Prepositions and B1 Exercises
Key takeaways
- Nominative, accusative, and locative cover most everyday and B1 exam sentences.
- Learn cases through common phrases like Widzę psa, not abstract declension tables.
- Genitive follows negation, quantities, and prepositions such as z, do, and bez.
- On the exam, the preposition or verb often tells you which case ending to use.
Polish has seven grammatical cases: nominative (mianownik), genitive (dopełniacz), dative (celownik), accusative (biernik), instrumental (narzędnik), locative (miejscownik), and vocative (wołacz). If that sounds intimidating, here is the good news: you do not need to master all seven at once. In everyday conversation and at the B1 exam level, three cases do most of the heavy lifting — nominative, accusative, and locative. Start there and build outward.
The nominative case is the default — the form you find in the dictionary. It is used for the subject of a sentence: 'Pies jest duży' (The dog is big). The accusative is used for direct objects and after many common verbs: 'Widzę psa' (I see the dog). Notice how 'pies' changed to 'psa' — that is the accusative form. The locative is used after prepositions like 'w' (in), 'na' (on), and 'o' (about) when describing location or topic: 'Mówię o psie' (I am talking about the dog). Learning these three cases covers the majority of sentences you will need.
The most practical approach is to learn cases through phrases, not tables. Instead of memorizing that masculine animate nouns take '-a' in the accusative, learn the phrase 'Widzę psa, kota, brata' (I see a dog, cat, brother). Your brain stores patterns attached to meaning much better than abstract rules. Build a collection of 10–15 common phrases for each case and practice them until they feel automatic.
The genitive case is the next one to prioritize. It is used after negation ('Nie mam psa' — I do not have a dog), after quantities ('dużo ludzi' — a lot of people), and after many prepositions like 'z' (from), 'do' (to), and 'bez' (without). The genitive is probably the most frequently tested case on the exam because it appears in so many constructions. Drill negation patterns and quantity expressions regularly.
The instrumental case is used after 'z' (with) and after the verb 'być' (to be) in predicate constructions: 'Jestem studentem' (I am a student), 'Idę z bratem' (I am going with my brother). The dative appears with verbs of giving and communicating: 'Daję bratu książkę' (I give my brother a book). The vocative is the rarest — used only when directly addressing someone: 'Panie profesorze!' (Professor!).
A common exam strategy: when you are unsure of the correct case ending, look at the preposition or verb. Polish prepositions almost always govern a specific case. 'W' + locative, 'do' + genitive, 'z' + instrumental (when it means 'with') or genitive (when it means 'from'). Memorize the preposition-case pairs as fixed chunks. On the exam, if you see a blank after 'w', you know the answer must be in the locative form. This mechanical approach gets you through most grammar questions without needing to fully analyze the sentence.
The seven cases at a glance
Use the questions to identify the case: ask the question from the verb or preposition, and the answer shows the form you need.
| Case | Questions | Main uses | Example |
|---|---|---|---|
| Mianownik (nominative) | kto? co? | subject; after “to jest” | To jest kot. |
| Dopełniacz (genitive) | kogo? czego? | negation, quantities, do / z / bez / od / u | Nie mam kota. |

| Narzędnik (instrumental) | (z) kim? (z) czym? | z = with; być + noun | Idę z kotem. |
| Miejscownik (locative) | o kim? o czym? | only after w, na, o, przy, po | Myślę o kocie. |
| Wołacz (vocative) | — | addressing someone | Kocie, chodź tu! |
Singular endings on four model nouns
These four nouns cover the most common singular patterns. Learn the table as a reference, then practise the forms in phrases like the ones above.
| Case | student (m., person) | dom (m., thing) | mama (f.) | okno (n.) |
|---|---|---|---|---|
| Mianownik | student | dom | mama | okno |
| Dopełniacz | studenta | domu | mamy | okna |
| Celownik | studentowi | domowi | mamie | oknu |
| Biernik | studenta | dom | mamę | okno |
| Narzędnik | studentem | domem | mamą | oknem |
| Miejscownik | studencie | domu | mamie | oknie |
| Wołacz | studencie! | domu! | mamo! | okno! |
Which preposition takes which case
Na and w take the locative for “where?” but the accusative for “where to?”. Z means “with” (instrumental) or “from” (genitive).
| Preposition | Case | Example |
|---|---|---|
| do, od, bez, dla, u, z (= from) | Dopełniacz | Jadę do Warszawy. Kawa bez cukru. |
| dzięki, przeciwko | Celownik | Dzięki mamie wszystko się udało. |
| przez, za (= for), na (where to?), w (+ day of the week) | Biernik | Idę na pocztę. Dziękuję za pomoc. W poniedziałek mam egzamin. |
| z (= with), przed, za (where?), nad, pod, między | Narzędnik | Idę z bratem. Czekam przed szkołą. |
| w, na (where?), o, przy, po | Miejscownik | Mieszkam w Krakowie. Rozmawiamy o pracy. |
