Questions & Answers about Moja sestra sutra mora da ide na posao.
Moja is the feminine singular form of the possessive adjective meaning my.
It changes to match the noun it describes:
- moj = masculine singular
- moja = feminine singular
- moje = neuter singular
Since sestra (sister) is a feminine singular noun, the correct form is moja sestra.
Examples:
- moj brat = my brother
- moja sestra = my sister
- moje dete = my child
Here sestra is the subject of the sentence, so it stays in the nominative case.
The sentence is about what my sister must do, so moja sestra is the one performing the action.
You would see another form like sestru if sister were the direct object, for example:
- Vidim sestru. = I see my sister.
But in:
- Moja sestra sutra mora da ide na posao.
moja sestra is the subject, so nominative is correct.
