IPA: /ˌkɒn.fjuːˈteɪ.ʃən/
KK: /kənˈfjuːteɪʃən/
The act of proving that something is wrong or false, often by presenting evidence or arguments against it.
The lawyer's confutation of the witness's claims was convincing and led to a change in the case's direction.
Confutation → It is formed from "con-" (meaning together) and "futare" (from Latin "futare", meaning to strike or beat). The word refers to the act of striking down an argument or proving it false, thus bringing together evidence against it.
Think of bringing evidence 'together' ('con-') to 'strike down' ('futare') an argument — that's what confutation means.
