Also compare Middle English knap, knappe (“small projection, knob (button, tassel, tuft, etc.), hill, hilltop, etc.)”), from Old English cnæp, cnæpp (“summit, top”), which is possibly related to Old Norse knappr (“small projection, knob (button, head of a stick, etc.)”) (whence English knop), from Proto-Germanic *knappô (“knob, lump”), *knuppô (“lump, clod”). Cognate with Dutch knob, knobbel (“knob”), German Knubbe, Knubbel (“knob”). See also knop. For the sense of a rounded hill, see nab and knab.
