Lending refers to the act of providing someone with something they need or want, usually on a temporary basis, and then expecting it back after a certain period. This can include money, objects, resources, or even time. The person who is lending out an item or service is called the lender, while the recipient is known as the borrower. Lending often involves some form of agreement between both parties to establish rules and expectations for the use and return of what is being loaned.
