catachresis

As you might have guessed, catachresis is a word favored by grammarians. It can sometimes be used merely as a fancy label of disparagement for uses the grammarian finds unacceptable -as when Henry Fowler insisted in 1926 that mutual in "our mutual friend" was a catachresis. (Fowler preferred common, but mutual does have an established sense which is correct in that context.) The earliest recorded uses of catachresis date to the mid-16th century, and it has been used to describe (or decry) misuses of a word ever since. Catachresis comes to us by way of Latin from the Greek word katachrēsis, which means "misuse."
