The word "lend" means to give something to someone temporarily, expecting that it will be returned. It is often used in the context of giving money, books, or other items to another person for a limited time. When you lend something, you trust the person you are giving it to will return it after using it.
The word "lend" originates from Old English "lendan," which means "to allow to borrow." The term has Germanic roots and is related to the Old High German "leitan" (to guide or lead) and Old Norse "lenda."
