What does the term "abet" mean?

The term "abet" specifically refers to the act of encouraging, supporting, or aiding someone in the commission of a crime or wrongdoing. It implies a level of complicity, meaning that the person who abets someone is not just passively observing but actively helping or instigating the undesirable action. This word is often used in legal contexts where someone may be charged as an accomplice to a crime, indicating their role in promoting or facilitating the unlawful act.

The other options, while they may sound plausible or related to other forms of encouragement, do not capture the specific nuance of "abet." One option refers to agreement or harmony, another speaks to advocacy or recommendation, and the last option describes expertise, none of which align with the meaning of encouraging wrongdoing.
