Did you know?
If an official talking about some policy refers to a collateral issue, he or she means something that may be affected but isn't central to the discussion. To an anthropologist, your cousin would be called a collateral relative, since he or she (unlike your grandmother, brother, or daughter) is "off to the side" of your direct line of descent. As a noun, collateral means something provided to a lender as a guarantee of repayment. So if you take out a loan or mortgage to buy a car or house, the loan agreement usually states that the car or house is collateral that goes to the lender if the sum isn't paid.
