No, I got your point, but as a lover of the English language, I find it irritating when people, such as yourself, excuse the maligning of words while simultaneously misusing words themselves. I was going to post a response which indicated that we should not concern ourselves with such trivialities and details since Obama was probably going to mandate a change in the acceptable definition of enormity because of his constant misuse of the word, but I found pointing out your little error much more satisfying.
Glad I could satisfy you. The real issue behind this is a battle of dictionaries. It seems Merriam-Webster believes that language should evolve and new words and/or definitions can be added simply by popular use. They recently added ‘meh’ after all. Whereas it seems the American-Heritage dictionary runs through a panel in an effort to protect or control or force, depending on your view of it, classic word usage rejecting popular usage.
