Questions & Answers about Ona živi u kući.
Because after u meaning in, Serbian normally uses the locative case for location.
- base form: kuća = house
- locative singular: kući = in the house / in a house
So:
- u kući = in the house
- u kuću = into the house
That second one uses the accusative and shows movement toward the inside, not location.
It is the locative singular of kuća.
In this sentence:
- Ona = she
- živi = lives
- u kući = in a house / in the house
The locative is commonly used after prepositions that describe location, and u is one of the most important ones.
Serbian does not have articles like English a/an and the.
So kuća can mean:
- a house
- the house
- sometimes even home, depending on context
The exact meaning usually comes from the situation, not from a separate article word.
