I like it, although it's quite pompous ("
Adel" means "nobility" in
German). Therefore I prefer
Adeline (pronounced a-de-LEEN).
Adelina I would prefer to be pronounced a-de-LEE-ne/a. The ah-sound in the beginning would make it sound stiff and stuck-up.
Not a fan of nicknames, but
Line and/or
Line would make sense to me.
