Questions & Answers about W niedzielę ta sama grupa gra w siatkówkę na tym samym boisku.
Why is it w niedzielę and not w niedziela or w niedzieli?
Because of case after the preposition and the meaning.
- Niedziela is feminine: nominative niedziela.
- With days of the week, w + accusative usually means “on (that day)” in a time sense.
So:
- nominative: niedziela – Sunday (as a subject: Niedziela jest…)
- accusative: niedzielę – on Sunday (time expression: w niedzielę)
- locative: niedzieli – used after some prepositions for location, not time.
In time expressions you say:
- w niedzielę – on Sunday
- w sobotę, w środę, w sobotę wieczorem, etc.
So w niedzielę is the standard way to say on Sunday in this habitual/time sense.
Why does the sentence start with W niedzielę and not with Ta sama grupa?
