Usage

What does collateral mean in loans? Collateral is an asset, such as a home or a car, pledged by a borrower that a lender accepts as security against a loan in case the borrower for any reason cannot pay back the loan. If a borrower fails to pay back a loan, the lender can seize the collateral and sell it in order to recover the loan amount.

Etymology

Origin of collateral

First recorded in 1350–1400; Middle English, from Medieval Latin collaterālis, equivalent to col- a variant of com- + Latin laterālis “on the side of the body”; see col- ¹ lateral

Explanation

It's what you promise to give someone if you don't repay a loan, like the car you put up as collateral when you take a loan out from the bank. As an adjective, collateral can refer to something indirect or off to the side, like collateral damage. Collateral is the watch you put on the table in a poker game, or the shoes you trade in at the bowling alley. If you pay back your debts, you get your goods back. As an adjective, collateral describes something indirect, like collateral damage (non-soldiers inadvertently killed in war) or collateral relatives such as your second-cousin-once-removed that your mother keeps bugging you to call.
