I agree that the etymology of "oxymoron" is itself an oxymoron, but I was thinking of "sharp/stupid" ( http://www.m-w.com/cgi-bin/dictionary?book=Dictionary&va=oxymoron ). Moros sounds like moron, so I looked it up ( http://www.m-w.com/cgi-bin/dictionary?book=Dictionary&va=moron ), and it says stupid, foolish. What is this other definition (moros=destiny, disgrace,death)?
