Root Explanation

Aspheric → It is formed from "a-" (meaning not) and "spheric" (from Greek "sphaira", meaning sphere). The word "aspheric" describes something that is not spherical or does not have the shape of a sphere.

Memory Tip

Think of 'not' ('a-') being combined with 'sphere' ('spheric') to remember that aspheric means something that is not shaped like a sphere.
