kink

From Middle English kinken, kynken, from Old English *cincian (attested in cincung), from Proto-West Germanic *kinkōn, from Proto-Germanic *kinkōną (“to laugh”), from Proto-Indo-European *gang- (“to mock, jeer, deride”), related to Old English canc (“jeering, scorn, derision”). Cognate with Dutch kinken (“to kink, cough”).

From Dutch kink (“a twist or curl in a rope”), from Proto-Germanic *kenk-, *keng- (“to bend, turn”), from Proto-Indo-European *gengʰ- (“to turn, wind, braid, weave”). Compare Saterland Frisian Kink (“twist or entanglement in a rope or cord”), Middle Low German kinke (“spiral screw, coil”), Old Norse kikna (“to bend backwards, sink at the knee”), Icelandic kengur (“a bend or bight; a metal crook”). Probably related to kick.
