Questions & Answers about Ea vizitează o mătușă a lor.
Why do we need the word a before lor?
Because mătușă (aunt) uses the indefinite article o (an). When you want to say "an aunt of theirs", Romanian requires a linking word to connect the noun and the possessive. Since mătușă is a feminine singular noun, the linking word is a.
Why use lor here?
lor means "their" or "theirs". It shows that the aunt belongs to a group of people, not just to the woman visiting (ea). If she were visiting her own aunt, it would be o mătușă a ei.
Does the word lor change if she visits an uncle instead?
