I'm sorry to spam things on the board as there are lots of people asking various things and this is probably an unnecessary question, but the search option isn't really helpful so I can't get any answer, and I guess I can get a more reliable answer here than anywhere else:
I've done the level "Possessive adjectives" and I've got a question - how often is this kind of thing used? Can't we go with just Genitive for possession or are the adjectival forms more popular for some nouns (like names and family members, like in the level)?
Also, something I've noticed - do they decline any different from regular nouns? (I mean, they of course have to agree with the noun they're describing, just that the patterns are the same as those of nouns).
