Questions & Answers about Moja sestra danas nosi haljinu, a ja nosim pantalone.

Why is it moja sestra and not moj sestra?

Because moj/moja/moje works like an adjective in Serbian, so it must agree with the noun it describes.

• sestra is feminine singular
• so my sister is moja sestra

Compare:

• moj brat = my brother
• moja sestra = my sister
• moje dete = my child

So moja is the feminine singular form needed for sestra.

What case is sestra in here?

• My sister is the person doing the action

So the basic dictionary form sestra is used here.
