Questions & Answers about W sobotę często oglądamy film wieczorem.
The preposition w (“in / on”) can take different cases in Polish.
- For days of the week with the meaning “on [day]”, w is followed by the accusative case.
- sobota (Saturday, nominative) → sobotę (accusative)
- w sobotę = “on Saturday”
Other examples:
- w poniedziałek – on Monday
- w piątek – on Friday
So w sobota is ungrammatical in this meaning; you must say w sobotę.
sobotę is accusative singular, feminine.
For many feminine nouns ending in -a in the nominative:
- nominative: -a → sobota, kawa, kolega (masc., but same pattern)
- accusative: -ę → sobotę, kawę, kolegę
So the -ę ending tells you the noun is in the accusative singular (here: required by w with a day of the week).
