I am so surprised that
Adele isn't more popular, and the only reason I can think of is because it's so associated with the singer, but it doesn't even make sense that that would make the name less popular!
Adele fits right in with the crowd that loves stuff like
Audrey and
Evelyn and
Eleanor and
Ava, etc. every once in a while I see people get excited over
Adela or
Adeline but never
Adele. I don't get it!
Enya feels way more tied to one person for me, because the singer with that name is the only
Enya I've ever heard of.
Adele I've seen around here and there.
I love them both.
Adele is more elegant, and
Enya is more fun. Reminds me of my youth, it's very "teenage wannabe-witch with an extensive amethyst collection who thinks she can telepathically speak with cats."
