Don’t worry, you can give baby the name Lex without dooming them to a life as a supervillain. While the name might be best associated with Lex Luther, Superman’s nemesis, it is also an ancient name with a powerful meaning. Lex is Greek in origin and is originally a diminutive of Alexander or Alexandra, which means “defender of mankind.” Many also link Lex to the Greek name Alexius meaning to “keep off” or “turn aside” as well as to “protect” and “help.” These days, Lex is a given name in its own right. It is a short and quippy name that not many on the playground will also have.
