A more thorough explanation:

Definition: A usury law is a legal regulation that prevents lenders from charging excessively high interest rates on loans.

For example, let's say a lender offers a loan with an interest rate of 50%. This would be considered usury and would be illegal under usury laws. In contrast, if the lender offers a loan with an interest rate of 10%, this would be considered legal under usury laws.

Usury laws are in place to protect borrowers from being taken advantage of by lenders who charge exorbitant interest rates. These laws vary by state and country, but they generally set a maximum interest rate that lenders can charge.
