Etymology: "Roundednesses" is the plural of "roundedness," a noun built from the adjective "rounded" plus the suffix "-ness," which turns an adjective into a noun for a quality or state. "Rounded" itself comes from "round," so the word describes the condition of being round or curved, and the plural form counts separate instances of that quality, such as the various smooth curves in a sculpture or a set of hills. Because "-ness" can be attached to almost any adjective in English, this is a straightforward compound of a common base and an everyday suffix rather than a word with a dramatic backstory. Its history is essentially that of its two parts, with the plural following the regular English pattern of adding "-es" to nouns ending in "-ss."
