Hi !!!
Ada,
Adele and
Adela have the same origin
adal meaning "noble" in Ancient Germanic.
Ada: simple and short. It doesn't need any nickname. I think that it is pretty ageless. In 2017 were born 131
Ada in Italy.
Adele (a-DEH-le): the most popular form right now. In 2017 were born 1,486
Adele in Italy (#31). It is the "traditional" form but I dislike it because it seems neutral, not the feminine form. If I were an official I would judge it unisex (actually it isn't but I like to consider it avallable for this role in the future, when unisex names will be used here in Italy too).
Adela: only 12 of them born in 2017. Infact it is Romanian, not strickly Italian. Between
Adele and
Adela I prefer
Adela for a girl.
So..tell me:
Which one and why?
