I was hoping someone could clarify the genitive case of nouns. I understand that it means possessive, but I don't understand why it seems to change.
Ex. pretty girl of mine = bella puella meae, or bella puellae meae, or bellae puellae meae?
Ex. girls of mine = puellarum mearum? puellas mearum? puellae mearum?
Thanks for any help.
