Questions & Answers about W niedzielę mamy przyjęcie urodzinowe.
In Polish, nouns change their form depending on the grammatical case.
- Niedziela is the basic (dictionary) form – nominative case (subject form).
- In w niedzielę, niedzielę is in the accusative case, which is used here because:
- w + accusative is used to express “on (a day)” in time expressions.
So:
- niedziela – nominative (e.g. Niedziela jest wolna. – Sunday is free.)
- w niedzielę – accusative (e.g. W niedzielę mamy przyjęcie. – On Sunday we have a party.)
You can’t say w niedziela; the noun must be in the correct case after the preposition w in this meaning.
Both are grammatically correct, but they mean different things and are used in different contexts:
w niedzielę – accusative; used for time:
- W niedzielę mamy przyjęcie. = We have a party on Sunday.
w niedzieli – locative; used for location inside something, usually abstract or very specific contexts (and sounds poetic or unusual here):
- szukać sensu w niedzieli = to look for meaning in Sunday (very stylized).
For everyday “on Sunday” in the sense of when something happens, you must say , not .
