Did You Know?

You probably know "crescent" as the shape of a moon that is less than half-illuminated. These days, "crescent" is generally used of either a waxing or waning moon, but that wasn't always the case. Originally, it referred only to the increasing illumination phase that immediately follows the new moon. That original meaning nicely reflects the meaning of the word's Latin ancestor crescere, which means "to grow." The meaning of "crescere" also shines through when we use "crescent" as an adjective meaning "increasing" or "growing." English speakers have been using "crescent" in this way since the 16th century.

Origin and Etymology of crescent

Latin crescent-, crescens, present participle of crescere —see 1crescent
