Definitions

1. Not having the shape or form of a circle
2. existing or occurring in a manner that is not round in nature
3. pertaining to structures, objects, or ideas that lack circularity and may take on various other shapes

Etymology: "Noncircular" is a plain formation: the prefix "non-", meaning "not", attached to "circular." The base word traces back through Latin "circularis," from "circulus," a diminutive of "circus," meaning "ring" or "circle," so "noncircular" simply means "not circular," with no circle in its shape. The adjective describes things that are not round or ring-shaped, whether physical structures, objects, or abstract ideas. Because it negates a shape rather than naming one, it can cover an open-ended range of forms, which is why the definition stresses that such things "may take on various other shapes."

Synonyms: irregular, non-round, asymmetric
