A more thorough explanation:

Definition: Covin (pronounced kuh-vin) is a term used in history to describe a secret agreement or conspiracy between two or more people to harm or cheat someone else. It can also be spelled as covine.

For example, if a tenant secretly agrees with someone else to help them win a lawsuit against the landlord, even though the tenant knows the lawsuit is unfair, that would be considered a covin.

Covin was often used in legal contexts to describe situations where people were working together in secret to harm someone else. It was seen as a serious offense and could result in legal consequences.
