Time for one of my periodic rants about the misuse of words. I've encountered two big ones in the same week, one of them twice.
The twofer is "slight" of hand instead of "sleight" of hand to mean prestidigitation, magic, fooling people, etc. Look, they sound the same, but mean different things, 'K? The only correct way to use "slight of hand" is to mean somebody with teeny, tiny hands. One of the goofs was in a newspaper article that should have been edited better, the other in a best-selling novel by an author who should know better.
