Questions & Answers about Gde je moj novčanik? Ne vidim ga u torbi.
Because novčanik is a masculine singular noun, and the possessive moj has to agree with it in gender, number, and case.
- moj = masculine singular
- moja = feminine singular
- moje = neuter singular
Since novčanik ends in a consonant and is masculine, moj novčanik is the correct form.
It is in the nominative singular.
In Gde je moj novčanik?, novčanik is the thing being asked about, so it stays in its basic dictionary form.
Serbian often omits subject pronouns when they are not needed.
So instead of saying something like Gde je on? or Gde je onaj novčanik?, Serbian simply says:
- Gde je moj novčanik?
The noun itself already tells you what the subject is, so no extra pronoun is necessary.
