A more thorough explanation:

Definition: Cosening is a deceitful practice that involves cheating or fraudulent dealing. It is also known as cozening. The term is often used to describe any guileful action that cannot be named by a specific term. In the civil law, it is called stellionatus.

Example: A salesman who convinces a customer to buy a product by making false promises is guilty of cosening. Another example is when a person tricks someone into giving them money by pretending to be a charity organization.

These examples illustrate how cosening involves using deceitful tactics to gain an advantage over someone else. It is a form of fraud that can have serious consequences for both the victim and the perpetrator.
