Did You Know?
The adjective gibbous has its origins in the Latin noun gibbus, meaning "hump," and in the Late Latin adjective gibbosus, meaning "humpbacked," which Middle English adopted in the 14th century as gibbous. Gibbous has been used to describe the rounded body parts of humans and animals (such as the back of a camel) or to describe the shape of certain flowers (such as snapdragons). The term is most often identified, however, with the study of astronomy. A gibbous moon is one that is more than a half-moon but less than full.
词根/词源演化：gibbus ("hump") / gibbsous ("humpbacked") --> gibbous
形容词gibbous根植于拉丁名词gibbus（隆起）与后拉丁语gibbosus（驼背），在14世纪被英语世界采用。gibbous这个形容词曾经被用于描述人体或动物体上的圆凸部分（例如骆驼隆起的背）或者描述某些种类的花朵（例如snapdragon金鱼草）。不过这个词在天文学研究中更被人熟知。gibbous moon（盈凸月）指的是月相中超过半月但未达满月的阶段。
注：
snapdragon - 金鱼草
