cackle

From Middle English caclen, cakelen, perhaps from Old English caclian, cacolian, from Proto-West Germanic kakulōn, kakilōn (“to cackle, gaggle, yelp, snarl”), perhaps of imitative origin. By surface analysis, cack + -le. Compare Dutch kakelen (“to cackle”), German Low German kakeln (“to cackle”), German kakeln (“to blather”), Danish kagle (“to cackle”), Swedish kackla (“to cackle”). Compare also Old English cahhetan, ċeahhettan (“to laugh loudly; cackle”), German gackern (“to cackle”).
