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 hunchback or camel) or to describe the shape of certain flowers (such as snapdragons). The term is most often identified, however, with the study of astronomy. In fact, if you run across the word gibbous, chances are you'll find the word moon somewhere nearby. A gibbous moon is one that is more than a half-moon but less than full.
