Word Origin & History

trap  (n.)
late O.E. træppe "snare, trap," from P.Gmc. *trap- (cf. M.Du. trappe "trap, snare"), related to Gmc. words for "stair, step, tread" (cf. M.Du., M.L.G. trappe, treppe, Ger. Treppe "step, stair"). Probably connected to O.Fr. trape, Sp. trampa "trap, pit, snare," but the exact relationship is uncertain. The connecting notion seems to be "that on which an animal steps." Sense of "deceitful practice, trickery" is first recorded 1681. Sense in speed trap recorded from 1906. Slang meaning "mouth" is from 1776. The verb is attested from 1393 (O.E. had betræppan); trap door is first attested c.1374. Trapper "one who traps animals" (for fur, etc.) is recorded from 1768.
