Questions & Answers about Moja radna biografija je spremna.
Because biografija is a feminine singular noun, and the possessive adjective moj (my) has to agree with it.
Agreement here is:
- moj = masculine singular
- moja = feminine singular
- moje = neuter singular
So:
- moj pasoš = my passport
- moja biografija = my biography / my CV
- moje pismo = my letter
Since the noun is biografija, you need moja.
For the same reason: radna must agree with biografija.
The adjective radan/radna/radno means something like work-related or employment-related here. Since biografija is feminine singular, the adjective also takes the feminine singular form:
- radni = masculine
- radna = feminine
- radno = neuter
So:
- radna biografija = work biography / resume / CV
This is standard adjective-noun agreement in Serbian.
