A news commentator on the radio, to which I was listening on my way home this afternoon, said that Dick Gephardt's announcement of his withdrawal from the Democratic presidential primary race was "anticlimatic." Really? I am quite certain that he meant "anticlimactic" but I have heard this mistake made so many times that I fear the error may overcome the proper term. Isn't there a word to describe an error which becomes so common that it "wins" in the sense of taking over from correct usage? Besides "stupid", I mean.
