Questions & Answers about Moj djed je stariji od moje bake.
The form of moj changes because it has to agree with the noun in gender, number and case.
moj djed
- djed = masculine singular, nominative (the subject)
- So we use moj = masculine singular, nominative
moje bake
- baka is feminine singular, but here it’s in the genitive (because of od, see below)
- So we use moje = feminine singular, genitive (the genitive form of moja)
Very roughly:
- moja baka = my grandmother (subject, nominative)
- moje bake = of my grandmother (after od, genitive)
So the difference is:
- moj → masculine, nominative (for djed)
- moje → feminine, genitive (for bake)
