Root Explanation

Concavity → It is formed from "con-" (meaning together) and "cavus" (meaning hollow). The word describes a shape that is hollowed out or curves inward, indicating a surface that is together in a hollow form.

Memory Tip

Think of a shape that is 'hollow' ('cavus') and 'together' ('con-') — this helps you remember that concavity refers to a surface that curves inward.
