I had known of several different meanings for her name, but I think some of the LK characters are so special that their names are defined by them. When I think of Nala, I think of love and beauty already because of who she is. When I think of Simba, I think of a strong leader lion because of who he is. Same for most of the names actually: Mufasa, Sarabi, Kiara, Kovu... and so on.

The way I see it, it gets to a point where the meaning of Simba or Nala is the characters themselves.
I didn't know about Halle Berry naming her daughter that though, that's really cool. She's beautiful to begin with, so her daughter just might live up to that name.
