Etymology

Origin of run-down

First recorded in 1675–85; adj. use of verb phrase run down

Explanation

Use the adjective run-down to describe something that's so old it's falling apart, like a beat up old car or a worn out mattress with springs sticking out of it. A dingy neighborhood that's seen better days can be called run-down, and so can your decrepit apartment building, with its broken elevator, creaky stairs, and windows that don't close all the way. A person can also be run-down, if he is bent and elderly, or just exhausted from traveling for days or working too many late nights. You can also spell it rundown, although the hyphenated run-down is more common.
