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”).
