Sage?

Is it too weird for a real life person?

Not at all weird! I hear it regarded as a name pretty often actually and I quite like it. It’s a nice alternative to [name_f]Paige[/name_f].

Not at all.

It isn’t weird at all. [name_f]Lovely[/name_f].

Definitely not. I know a girl and a boy named [name_u]Sage[/name_u]. It’s absolutely usable.
