plural autoantonyms

Definition of autoantonym

: contronym I loved “perspicacious” and “recondite” and “hortatory” and “cleave,” the last of which meant the opposite of itself, both to join and to tear apart. “Impregnable” was an autoantonym, too. It was like a snake that ate its own tail.— Joshua Henkin, New York Times, 25 Aug. 2013
