gab

Origin

From Middle English gabben, from Old English gabban (“to scoff, mock, delude, jest”) and Old Norse gabba (“to mock, make sport of”); both from Proto-Germanic *gabbōną (“to mock, jest”), from Proto-Indo-European *gʰeh₁bʰ- (“to be split, be forked, gape”). Cognate with Scots gab (“to mock, prate”), North Frisian gabben (“to jest, sport”), Middle Dutch gabben (“to mock”), Middle Low German gabben (“to jest, have fun”).
