Questions & Answers about Do tych dżinsów potrzebuję nowego paska, bo stary jest już za krótki.
Because do here means something like for / to go with in this context, and the preposition do requires the genitive case.
So:
- te dżinsy = these jeans (nominative)
- do tych dżinsów = for these jeans / for these jeans here (genitive after do)
In this sentence, do tych dżinsów means for these jeans, in the sense of to wear with these jeans.
Both words are in the genitive plural because they follow do.
Base form:
- te dżinsy = these jeans
After do:
- tych dżinsów
Breakdown:
- te → tych
- dżinsy → dżinsów
This is a normal case change in Polish. English does not do this much, so it often feels unusual at first.
