Root Explanation

Convexity → It is formed from "con-" (meaning together) and "vexare" (meaning to shake or disturb). The word describes a shape that curves outward, as if all points are being pushed together from the inside.

Memory Tip

Think of a shape that is 'pushed out' ('vexare') from the center, which helps you remember that 'convexity' refers to the outward curve of a surface.
