Etymology
The word 'roundness' is a straightforward formation from the native English adjective 'round'. 'Round' itself descends from the Old French 'rond', which has Latin origins in 'rotundus' (rolling, circular), ultimately tracing back to the Proto-Indo-European root ret- meaning "to run, roll." The suffix '-ness' is a prolific and ancient English morpheme from Old English '-nes', used to form abstract nouns denoting a state or quality. Therefore, the literal construction "the state of being round" directly and logically yields the modern abstract meaning describing circularity or completeness.
