In English, if I want to say something like "my beloved aunt and uncle", beloved is understood to modify both words. How do you do this in Italian if the two words are masculine and feminine (or at all, if "mia zia e mia sorella diletta" doesn't modify both)?
My best attempt is "mio zio e mia zia diletti" thinking that the beloved becomes plural. Is there a more eloquent way of doing this other than "mio zio diletto e mia zia diletta"?
