Confucius say...

Sophomores are wise fools. No, really - according to my Greek book, σοφος "wise" + μωρος "foolish" = sophomore "wise foolish one." The "official" etymology in my Oxford etymological dictionary gives it as an obsolete form of "sophism" + "-er" = "one who makes sophisms." Personally, I find my Greek book's version both more plausible and a lot more interesting. After all, who doesn't like having an oxymoron for a name? (As an aside, οξυς "sharp" + μωρος "foolish" = oxymoron "a pointedly foolish thing.")
