Taken from several different lists on Nameberry. I left out some that, to me, are completely unusable. And of course these are only some of the word names out there, I'm sure I'm forgetting some good ones too. Of course, some of these are nature names, but they're also words, so I count them. I'll probably make one for girls' names later.
It's interesting because a handful of names here you don't necessarily look at as words if you see it as a name.
