The term contronym was coined by Jack Herring in 1962. Such words are also referred to as auto-antonyms or Janus words (after the Roman god Janus, who is depicted with two faces.)
Why do they occur?
Some contronyms are distinct words with different etymologies that come into the language in the same form or spelling, eg., rock, as in “a solid mineral material” (Old North French), or “rock a child” (Old Norse).
Other Janus words happen where a single word acquires different and sometimes opposite definitions. The word sanction, for example, diverged over time to mean both “permit” and “penalize.”
Auto-antonyms can also result from nouns being verbed, like dust. If you say, “I’m dusting the room,” it’s highly unlikely that you’re sprinkling dust on the tabletops in the same manner as powdering a cake with sugar.
Contronyms may occur due to varying dialects in the same language. In British English, to table a bill means “to put up for debate, whereas in American English, it means “to remove from a debate.”
Though the examples are numerous, here is a short list of 25 common contronyms:
bolt – to secure or to flee
bound – heading to a destination or restrained from movement
buckle – to connect or to break or collapse
clip – to fasten together or cut away
consult – to offer advice or to obtain it
