That's what I think when I hear "nouveau". That and
Art Nouveau. I definitely don't find it attractive as a female name (as others have pointed out, it is a masculine form).

Asha looks much more clean and pronounceable than Aasha. Why the extra a? So she'll always be the first person in her class alphabetically? (Unless there's an
Aaron ;-))
