Root Explanation

Unstoppable → It is formed from "un-" (meaning not) and "stop" (from Old English "stoppian", meaning to close or block) and "-able" (meaning capable of). The word "unstoppable" means not capable of being stopped or unable to be blocked.

Memory Tip

Think of something that is 'not' ('un-') able to be 'blocked' ('stop') — that's why we say it is unstoppable.
