The English major in me cringes to hear Bush speak. His assault on our language began even before he was elected. While many of his "Bushisms" are harmless, there have been quite a number of direct hits that have corrupted the meaning of once clearly denotated terms. This occurs when the entire administration gets behind a specific word to, as Orwell would have put it, wrap it up in meaning that supports the party. The press has exaccerbated the situation.
Here's a short list of terms I consider horribly corrupted by this administration. I invite you to add your own.
