Declention/mutations of possessive pronouns?
I'm asking since I can't find any information about it on the Internet - do the irish possessives undergo mutations or declention? For example if I wanted to ask "Where are you, my wife?" - would be "Cá bhfuil tú, a mho bhean?" or "Cá bhfuil tú, a mo bhean?"? Or maybe we just skip the "a" in that case ("Cá bhfuil tú, mo bhean?") or use some completely different structure?
Thanks in advance :)
about the possessive adjectives themselves, I know that the nouns after the possessives are lenited/eclipsed. And not only in vocative, in any situation that would normally trigger the mutation (besides vocative it could be for example the situation like "in your apple" - would it be "i nd'ull" ?
Setting aside prepositional forms, the possessive adjectives are not mutated, other than mo → m’, do → d’ before a vowel or fh + vowel. They are only declined for person and number. Possessive adjectives aren’t used in the vocative — for example, one would address someone as “my friend” using a chara. “In your apple” would be i d’úll.
