　　I couldn’t agree more!

　　That’s absolutely true!

　　Absolutely!

　　I take your point.

　　I’d go along with you there.

　　I’m with you on that.

　　That’s just what I was thinking

　　That’s exactly what I think

　　That’s good point

　　That’s just how I see it.

　　That’s exactly my opinion.

　　2. How to half agree with an opinion.

　　Yes, perhaps.

　　Well, yes.

　　Yes, in a way

　　Mum, possibly

　　Yes, I agree up to a point

　　Well, you’ve got a point there.

　　There’s something in that, I suppose

　　E guess you could be right

　　Yes, I suppose so.

　　That’s worth thinking about.

　　3. How to disagree politely with an opinion

　　Well. It don’t know.

　　Well, I’m not so sure about that.

　　4. How to disagree strongly with an opinion

　　I disagree.

　　I disagree with you entirely.

　　I’m afraid I don’t agree.

　　I’m afraid you are wrong there.

　　I really can’t agree.

　　I wouldn’t accept that for one minute.

　　You can’t really mean that.

　　I wouldn’t go along with you there.

　　You can’t be serious.

　　You must be joking.

　　Note that you need to be very polite when disagreeing with someone in English, even someone you know quite well. With someone you know very well, you can disagree more directly.
