Etymology

convex = con<together> + vex<to bend>

  • con<together>: From Latin cum, meaning "with" or "together."
  • vex<to bend>: From Latin vexare (to shake, agitate) and vexus (arched, bent), related to the idea of curvature.

Etymology Origin:
The word "convex" originates from Latin convexus, combining con- (together) and vexus (bent). It originally described a shape bent outward, like the surface of a dome. The term evolved in scientific and mathematical contexts to denote surfaces that curve outward uniformly, contrasting with "concave." The logic lies in the visual unity (con-) of the bending (vex) direction.
