Here's the sentence I've composed. すしを買うことについて、母を尋ねる。 The meaning I intend is something like, "I'll ask my mom about buying sushi," like I'm telling my friend I'll be asking her for permission to do so. I'm unsure if this is grammatically correct in multiple respects-- can I use 買う as I did or does that require a different conjugation, like the potential, and does the について serve the purpose of blocking that whole idea off as what I will ask my mother? My logic in composing it was like, "The idea of buying sushi, regarding that, (I will) ask my mother." Thank you in advance.
