Bourgeois Babbling

William Deresiewicz points out that the distortion of the English language often starts with the elite:

There is a lesson here. Idiomatic mistakes, at least the ones that stick, are not produced by the hoi polloi. They happen when people try to sound educated—or to be precise, when educated people try to sound more educated than they actually are. A little learning is a dangerous thing. You hear a word like vagariesor misnomer, you think it sounds impressive, you think you know what it means, and you deploy it the next chance you get. And then somebody who has less cultural capital than you, and who looks to you as an authority, picks it up and uses it in turn.
