Confutation means refuting an argument or proving it wrong. Some of the antonyms for this word are affirmation, approval, agreement, endorsement, and validation. An affirmation is a declaration that something is true, without any contradiction. Approval means giving permission or consent to something, showing agreement or satisfaction. Agreement signifies harmony in opinion, thought or action between two or more parties. Endorsement implies supporting or recommending a person, idea, or product. Validation refers to the act of proving or confirming the truth or accuracy of something. While confutation may often be necessary in controversial discussions, the opposite end of the spectrum involves finding common ground and agreeing with one another.
