I like this a lot. Its definitely a nicer alternative to Ava and I never really thought of "ate-a" until you said it. I don't think many people would notice that, anyway. I heard a song by Sarah McLachlan called Adia (prn. Ay-dee-ah) and I thought that it would make such a beautiful name.
I love Ada, and I've never thought it sounded like "ate-a" but now I probably will. :-/ LOL. It's a nice alternative to the trendy Ava, but it's possible it will become popular in the future for that very reason. :(
