Questions & Answers about Fotelja je u novom stanu.
Because after u meaning in, Serbian uses the locative case to show location.
- base form: stan = apartment / flat
- locative singular: stanu = in the apartment
So:
- u stanu = in the apartment
If u shows movement into something, then Serbian usually uses the accusative instead:
- u novi stan = into a new apartment
So in Fotelja je u novom stanu, the chair is already located there, so locative is used.
Because adjectives must agree with the noun they describe in:
- gender
- number
- case
Here, stan is:
- masculine
- singular
- in the locative
So the adjective nov changes to match it:
- nominative: novi stan
- locative: u novom stanu
That is why you get novom stanu.
