Phrases:

Origin:
late 16th century (originally denoting a harness-maker, then a slaughterer of horses): possibly from obsolete knack ‘trinket’. The word also had the sense ‘old worn-out horse’ (late 18th century). knacker may be from dialect knacker ‘castanet’, from obsolete knack ‘make a sharp abrupt noise’, of imitative origin. It is unclear whether the verb represents a figurative use of ‘slaughter’, from knacker, or of ‘castrate’, from knacker
