Etymology[edit]

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