I like
Adelina, but Adelino doesn't really do anything for me. Not a surprise, since I like
Antonia and not
Antonio,
Francesca and not
Francesco, and so on. I'm not sure why that is, honestly; the female ones sound graceful and elegant, whereas the male ones usually just sound...a bit arrogant, I guess. I feel like that could change if I met one, but right now that's my stance.
I think I'd like it better as Adalino; that way it reminds me of
Adalbert, which makes me happier for some reason.
