handcuff

Etymology

1640, from hand + cuff (“end of shirtsleeve”). Possibly an adaptation of Middle English handcops (“shackles for the hand, handcuffs”), from Old English handcops, from hand + cops, cosp (“fetter, chains”), but due to lack of continuity (centuries between Old English and modern term), generally analyzed as a re-invention.

noun

1. One ring of a locking fetter for the hand or one pair.

verb

1. To apply handcuffs to
