Don't Get Tired Defining Knackered

Knackered is derived from the past participle of knacker, a slang term meaning "to kill," but also "to tire, exhaust, or wear out." The origins of the verb knacker are uncertain, but the word is perhaps related to an older noun knacker, which originally was used to indicate a harness-maker or saddlemaker, and later for buyers of worn-out animals (or their carcasses) and old structures. The origins of the noun knacker, however, remain obscure. Knackered is used on both sides of the Atlantic but is more common among British speakers.
