Etymology: Convexity is a plain formation: the adjective "convex" plus the suffix "-ity", which turns a quality into a noun. "Convex" itself came into English from Latin "convexus", meaning arched or vaulted, a word built from "con-" (together) and "vehere" (to carry), so the original sense was something carried upward into a curve. The idea of a surface bulging outward is already there in the parent word. The suffix has a longer ancestry than the word it sits on. Its distant source is a Proto-Indo-European element that Latin turned into "-itās", which passed through Old French "-ite" and Middle English "-ite" before settling into the modern "-ity". English adopted it in large numbers to build abstract nouns from adjectives, so "convexity" follows a pattern shared by words such as "density" and "rapidity".
