Questions & Answers about Moja sestra ima sina i kćer.

Why is it moja sestra and not moj sestra or moje sestra?

In Croatian, possessive adjectives like moj (my) must agree with the noun in:

• gender (masculine / feminine / neuter)
• number (singular / plural)
• case

Sestra (sister) is:

• feminine
• singular
• nominative (it is the subject)

The basic forms of moj in the nominative singular are:

• masculine: moj (e.g. moj brat – my brother)
• feminine: moja (e.g. moja sestra – my sister)
• neuter: moje (e.g. moje dijete – my child)

So you must say moja sestra because sestra is feminine singular.

Why is it sestra and not sestru?

Sestra is the subject of the sentence, so it is in the nominative case.

• Moja sestra – nominative (who/what has something? → my sister)

If sestra were the object, you would usually see sestru (accusative):

• Imam sestru. – I have a sister.
  • Here sestru answers “whom do I have?” (direct object → accusative)

In your sentence, my sister is the one who has the children, so it stays in nominative: moja sestra.
