Why “rondure” is a great word
RONDURE — [Noun] A graceful curvature, a round object or sphere, or the quality of being round. Borrowed from French rondeur ("roundness; round object"), from rond ("round") + -eur (suffix forming agent nouns). First attested in English 1590–1600. Unlike "sphere," which denotes a precise geometric solid, or "circularity," a technical property, rondure is the aesthetic essence of pleasing roundness. It is the soft arc of a dove's breast, the pregnant swell of a ripening fruit, and the horizonless completeness of a dewdrop suspended from a leaf—a quiet testament to the world's inclination toward closure.
