A more thorough explanation:

COSEN

cozen (kə-zən), verb. This is an old-fashioned word that means to cheat or defraud someone.

• He tried to cozen his way out of paying the bill by claiming he had already paid.
• The salesman cozened the old lady into buying a product she didn't need.

These examples show how someone can use deceitful tactics to cheat or trick someone else. In the first example, the person tries to avoid paying a bill by lying about already paying it. In the second example, the salesman convinces the old lady to buy something she doesn't need by using dishonest methods.
