Questions & Answers about Moja sestra me čeka na stanici.
Why is it moja sestra, not moj sestra?
Because sestra is a feminine singular noun, and the possessive adjective moj has to agree with it in gender, number, and case.
So:
- moj brat = my brother
- moja sestra = my sister
- moje dete = my child
Here, sestra is feminine singular in the nominative, so the correct form is moja.
Why is sestra in this form?
Sestra is the subject of the sentence, so it is in the nominative case, which is the basic dictionary form.
In Moja sestra me čeka na stanici:
- moja sestra = the subject, the person doing the action
- me = the object, the person being waited for
So sestra stays in nominative because my sister is the one who is waiting.
Why do we use me instead of ja or mene?
Because me is the short unstressed accusative form of the pronoun ja.
Compare:
- ja = I
- mene = me, longer/stressed form
- me = me, short unstressed form
