Etymology

Origin of abet

First recorded in 1275–1325; Middle English abette (source of Old French abeter, unless the latter, of Germanic origin, is the source of the Middle English), unattested Old English ābǣtan “to hound on,” equivalent to ā- a- 3 + bǣtan “to hunt, chase with dogs, pasture”; see origin at bait; akin to bite

Explanation

To abet is to help someone do something, usually something wrong. If you were the lookout while your older sister swiped cookies from the cookie jar, you abetted her mischief. The verb abet can be used to generally mean encouragement, but people usually expect to see it in relation to some crime. "The singer was abetted by a pianist in her rendition of Silver Bells," for example, is a harmless construction. However, people more often expect abet in a sentence like this: "She was charged with aiding and abetting the burglar because she drove the getaway car." Abet comes from an Old French word abeter meaning "to bait."
