Root Explanation

Concave → It is formed from "con-" (meaning together) and "cavus" (meaning hollow). The word describes a shape that is hollowed out or curves inward, as if coming together to form a dip.

Memory Tip

Think of a shape that is 'hollow' ('cavus') and 'together' ('con-') — that's why concave refers to something that curves inward.
