When I read the title, I tought it was about the meaning of the name of our characters. It isn't, but would be nice if it was.
EDIT: after reading V_S post, I think it's really about the meaning, right?
Well, my custom's names are: Bob, Franklin, Ishtos, Onorin and Vatre.
-Bob and Franklin are common names, they have nothing to represent.
-Ishtos comes from the greek ishýs (fonetic form) that means power and entós (fonetic form) that means inside. So, Ishtos means power from inside (completely cliche, I know).
-Onorin comes from the greek too, but I don't remember what it means, I just know it has something with wisdom.
-And finally Vatre, I don't remember what it means, actually, I have no idea of the meaning, I just know it comes from the serbian.
Actually nothing with Japanese... :S
