Questions & Answers about Njena mačka spava na balkonu kad je sunce jako.
Njena is a possessive adjective meaning her (as in her cat).
- It comes from the pronoun ona (she).
- It must agree with the noun it describes in:
- gender → mačka is feminine
- number → mačka is singular
- case → here mačka is in the nominative (it’s the subject)
So you get njena mačka = her cat (feminine, singular, nominative).
Yes, you can also say Njezina mačka spava na balkonu kad je sunce jako.
- njena / njen and njezina / njezin are two sets of forms for her (possessive).
- In many descriptions of standard Croatian, njezina is the “more correct / textbook” form, and njena is very common in everyday speech.
- In practice, you will hear and read both, and everyone will understand both.
As a learner of Croatian, it’s safe to use njezina if you want to stick closely to the textbook standard, but you will constantly hear njena as well.
