Conversation

Did you hear about the new evidence they found in that case?

Yeah, I did! It's supposed to be irrefutable this time.

That's what they say, but I wonder if it will change anything.

It should, especially if the proof is truly irrefutable.

Root Explanation

Irrefutable → It is formed from "in-" (meaning not) and "refutare" (meaning to disprove or rebut). The word "irrefutable" means something that cannot be disproven or is undeniable.

Memory Tip

Think of something that is 'not' ('in-') able to be 'disproved' ('refutare') — that's why irrefutable means it cannot be denied.
