Questions & Answers about Z naszego balkonu widać park i boisko.
In this sentence, z means from:
- z naszego balkonu = from our balcony
Polish z can mean different things depending on the case that follows:
- z + genitive = from / out of
- z + instrumental = with
Here it is followed by naszego balkonu, which is genitive, so the meaning is from.
Because the preposition z meaning from requires the genitive case.
So:
- nasz balkon = our balcony (dictionary/basic form)
- z naszego balkonu = from our balcony (genitive after z)
Both words change:
- nasz → naszego
- balkon → balkonu
This is very normal in Polish: prepositions often force a particular case.
