Root Explanation

Impassable → It is formed from "im-" (meaning not) and "passare" (meaning to pass). The word describes something that cannot be passed through or crossed.

Memory Tip

Think of 'not' ('im-') being able to 'pass' ('passare') — that's why impassable means something you cannot pass through.
