Did you notice how his underlip twitched when he was nervous?

Root Explanation

Underlip → It is formed from "under" (from Old English "under", meaning beneath or below) and "lip" (from Old English "lippa", meaning the edge of the mouth). The word "underlip" refers to the lip that is located beneath the upper lip.

Memory Tip

Think of something that is 'beneath' ('under') the 'edge of the mouth' ('lip') — that's why underlip refers to the lower lip.
