Root Explanation

Inexhaustible → It is formed from "in-" (meaning not) and "exhaustus" (from Latin "exhaurire", meaning to draw out or drain). The word describes something that cannot be drained or used up.

Memory Tip

Think of something that is 'not' ('in-') able to be 'drained' ('exhaustus') — that's why inexhaustible means it cannot be used up.
