Did You Know?
An apt synonym for knackered might be the phrase “dead tired” for more than one reason. Knackered comes from the past participle of knacker, a slang term meaning “to kill,” as well as “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. That word originally referred to a harness-maker or saddlemaker, and later to a buyer of animals no longer able to do farmwork (or their carcasses), as well as to a buyer of old structures. Knackered is used on both sides of the Atlantic but is more common among British speakers.
