wiktionary
From Middle English cuffe, coffe(“glove, mitten”), of obscure origin. Perhaps from Old English cuffie(“hood, cap”), from Medieval Latin cofia, cofea, cuffa, cuphia(“helmet, headdress, hood, cap”), from Frankish *kuf(f)ja(“headdress”), from Proto-West Germanic *kuffju, from Proto-Germanic *kupjō(“cap”). Cognate with Middle High German kupfe(“cap”).
1520, “to hit”, apparently of North Germanic origin, from Norwegian kuffa(“to push, shove”) or Swedish kuffa(“to knock, thrust, strike”), from the Proto-Germanic base *skuf-(skuƀ), from Proto-Indo-European *skewbʰ-, see also Lithuanian skùbti(“to hurry”), Polish skubać(“to pluck”), Albanian humb(“to lose”).
Germanic cognates include Low German kuffen(“to box the ears”), German kuffen(“to thrash”). More at scuff, shove, scuffle.
