From Middle English knokel (“finger joint”), from Old English cnucel (“the juncture of two bones; knuckle; joint”), from Proto-West Germanic knukil, from Proto-Germanic knukilaz (“knuckle, knot, bump”), as knukô (“bone, joint”) + -ilaz (diminutive suffix). Cognate with Dutch knokkel (“knuckle”), Low German Knökel (“knuckle”), German Knöchel (“ankle, knuckle”), Old Norse knykill.
