What does abet mean?
To abet is to encourage, support, or help someone carry out something wrong or unlawful. The word belongs chiefly to the formal vocabulary of law and journalism: courts speak of those who 'aid and abet' a crime, meaning people who knowingly assist or incite it even if they do not commit the act themselves. An accomplice who drives a getaway car, a colleague who conceals fraud, or a bystander who urges on a fight can all be said to have abetted the offence. Although its core sense once simply meant to urge or encourage, modern usage almost always carries a strongly negative implication of complicity, and using the word about lawful activity sounds ironic or archaic at best. It functions as a transitive verb, typically taking a person or an act as its object, and appears most naturally in phrases such as 'charged with abetting the theft'. Knowing 'abet' is useful for understanding legal reporting and for expressing culpable encouragement precisely.

The legal phrase 'aiding and abetting' is so entrenched in English that 'abet' is now almost never used without its partner 'aid' — a word kept alive entirely by one famous phrase.

Etymology of abet
Abet comes from the Old French verb 'abeter', formed from 'a-' (from Latin 'ad', meaning 'to') plus 'beter' (to bait or hound), which itself traces back through French to Old Norse 'beita', meaning to cause to bite. In medieval hunting language, to abet was literally to set dogs upon an animal by baiting them — urging them on toward their quarry. From this sense of inciting dogs, the word broadened to mean encouraging or instigating any action, and eventually settled into its modern legal sense of assisting wrongdoing. Related English words sharing this Germanic root include 'bait' and 'bate'.
