Etymology: "Hemicircular" is a plain compound: "hemi-", from Greek "hēmi-" meaning "half", joined to "circular", which itself comes from Latin "circularis", derived from "circulus", a little circle. Put together, the word simply means "half-circular," describing something shaped like one half of a circle. The Greek prefix "hemi-" appears in many scientific and technical English words, such as "hemisphere" and "hemiplegia," and it is the same element that gives us "semi-" through a different route. Here it is attached to an adjective describing circular form, so the word's structure is transparent: it says exactly what it describes.

Synonyms: semi-circular, half-circular, curved, arched, rounded
