Questions & Answers about Moja sestra često kuva pirinač i meso za ručak.
Because moja has to agree with sestra in gender, number, and case.
- sestra is feminine
- singular
- nominative here
So the possessive adjective moj changes to moja.
Compare:
- moj brat = my brother
- moja sestra = my sister
- moje dete = my child
Sestra is in the nominative case because it is the subject of the sentence — the person doing the action.
In this sentence, moja sestra is the one who često kuva, so nominative is used.
Kuva is the 3rd person singular present tense form of the verb kuvati = to cook.
It matches moja sestra, which is equivalent to she.
So:
- ja kuvam = I cook
- ti kuvaš = you cook
- on/ona kuva = he/she cooks
