Other forms: lenders
A lender is a person or business that loans money. If you need cash to get your lemonade stand up and running, you'll have to find a lender and borrow 20 dollars or so for lemons and sugar.
Banks are often described as lenders, especially when they give mortgage loans to people who need a lot of money to buy a house. If you receive money from a lender, that makes you a borrower or a debtor — you owe that money, plus interest, and you'll have to pay it back. Lend shares a root with loan, as well as the Old English læn, "gift."
