Questions & Answers about Babcia czyta gazetę przy oknie.
Because gazeta is the direct object of the verb czyta (reads), so it has to go into the accusative case.
- dictionary form: gazeta
- accusative singular: gazetę
This is very common with feminine nouns ending in -a:
- książka → książkę
- herbata → herbatę
- gazeta → gazetę
So Babcia czyta gazetę means Grandma is reading a newspaper, with gazetę showing what is being read.
Because the preposition przy requires the locative case.
The noun okno changes like this:
- nominative: okno
- locative: oknie
So:
- przy oknie = by/at the window
Many Polish prepositions force a specific case, and przy is one of them.
