To confute someone, or an argument, is to prove it completely wrong — not just to disagree, but to show, with reasons or facts, that it cannot stand. It is an old, formal verb. You will meet it in serious writing, law, or debate, far more than in chat. Though actually, most people today reach for refute or prove wrong instead; confute sounds like a book from another century. It is still useful when you want that extra force: the other side is not “a bit off”; it has been knocked down. It is about winning on the facts, not about shouting louder.
