History

Etymology

From Middle English gibbous, from Latin gibbus (“humped, hunched”), probably cognate with cubō (“bend oneself, lie down”), Italian gobba (“humpback”), Ancient Greek κῡφός (kūphós, “humpback, bent”), κύβος (kúbos, “cube, vertebra”), Spanish giboso (“humped”). Also ultimately compare dialectal Norwegian keiv (“slanted, wrong”), German schief (“crooked, slanting”) and Dutch scheef (“crooked, slanting”).
