IPA: /kənˈfjuːtə/
KK: /kənˈfjuːtər/
A person who argues against or disproves a statement or belief.
The confuter presented strong evidence to challenge the theory.
Confuter is formed from "con-" (meaning together) and "futere" (meaning to strike or beat). The word describes the act of striking down an argument or assertion together with evidence or reasoning, thus refuting it.
Think of 'striking down' an argument ('futere') together ('con-') — that's why confuter means to refute or disprove.
