Etymology

Origin of arrears

1300–50; noun use of arrear (adv., now obsolete), Middle English arere behind < Middle French ≪ Latin ad retrō. See ad-, retro-

Explanation

If you are in arrears, you are behind in the payment of a debt. Think: rears = behind. Arrears also refers to the unpaid, overdue debt itself. Your rent arrears are the money you owe on rent. Arrears is a term often used in a legal context — like, when you've had to hire a lawyer because you're being sued by your landlord, or being evicted because you're in arrears on your rent. Before it comes to eviction, though, you should try negotiating with your landlord first. They would probably be more interested in collecting arrears, even late, than in evicting you and starting with a new tenant from scratch.
