Root Explanation
Indisputable is formed from "in-" (meaning not) and "disputare" (meaning to argue or debate). The word describes something that cannot be argued against or is beyond dispute.
Memory Tip
Think of something that is 'not' ('in-') able to be 'argued' ('disputare') — that's why indisputable means it cannot be disputed.
