The word circular traces back to Latin circularis, derived from circus (circle). The root circ- has consistently denoted circularity across languages (e.g., circus, cycle). The suffix -ular systematically converts nouns into adjectives, emphasizing shape or relation. The term evolved in Middle English to describe both physical roundness and repetitive processes (e.g., circular reasoning).
