Etymology

From Middle English knokken, from Old English cnocian, ġecnocian, ġecnucian, cnucian (“to knock, pound on, beat”), from Proto-West Germanic *knokōn, from Proto-Germanic *knukōną (“to knock”), a suffixed form of *knu-, *knew- (“to pound on, beat”), from Proto-Indo-European *gnew-, *gen- (“to squeeze, pinch, kink, ball up, concentrate”). The English word is cognate with Middle High German knochen (“to hit”), Old English cnuian, cnuwian (“to pound, knock”), Old Norse knoka (compare Danish knuge (“to squeeze”), Swedish knocka (“to hug”)).
