Questions & Answers about Podwórko za kamienicą jest ciche rano.
Because the preposition za can require different cases depending on meaning.
Here it means behind in a location sense, so it takes the instrumental case:
- kamienica = base form, nominative
- kamienicą = instrumental singular
So:
- za kamienicą = behind the building
If za expresses motion to a place, it often takes the accusative instead, but in this sentence it describes location, not movement.
Kamienica usually refers to a traditional multi-storey urban building, often translated as:
- tenement building
- townhouse building
- apartment building
depending on context
In many Polish cities, a kamienica is a classic older city building facing the street, often with a courtyard behind it.
So podwórko za kamienicą suggests a courtyard behind that kind of building.
