ABUSAGE
Etymology
First appeared in the 16th century as a general synonym of abuse, but fell into disuse after just a couple of centuries. The word re-emerged with a new grammar-specific sense after Eric Partridge published a book on grammar titled Usage and Abusage: A Guide to Good English (a pun on "use and abuse") in 1942.
