Root Explanation

Undebatable → It is formed from "un-" (meaning not) and "debatable" (from Latin "debatere", meaning to discuss or argue). The word "undebatable" means not open to discussion or argument.

Memory Tip

Think of 'not' ('un-') allowing for any 'discussion' ('debatable') — that's why undebatable means something that cannot be argued.
