In every discussion I make I always end up replying late and the idea I have in my mind were also already express in a reply of someone else. So, I have make a quick search on ways to express agreement and disagreement on someone else post and will add ideas if it is applicable.
Here are some ways in expressing agreement,That’s right/You’re right/I know: - used when agreeing with someone:
‘It’s supposed to be a very good school.’ ‘That’s right. They get great results.’
‘He’s really boring, isn’t he?’ ‘Oh, I know, he never stops talking about himself.’
Exactly/Absolutely/I couldn’t agree more: used for saying that you completely agree with someone:
‘When we were young, people didn’t get into debt.’ ‘Exactly. You just bought what you could afford.’
‘I think Jacob is the best person for the job.’ ‘Absolutely. I’ll be amazed if he doesn’t get it.’
‘We had to wait three months to get a phone line – it’s ridiculous.’ ‘I couldn’t agree more.‘
You can say that again/You’re telling me: a more informal way of saying that you completely agree with someone:
‘It’s so cold outside!’ ‘You can say that again!‘
‘The buses are so unreliable!’ ‘You’re telling me! I’ve been waiting here for half an hour.’
Why not? used when agreeing with a suggestion someone has made:
‘Let’s go to the cinema tonight.’ ‘Why not? We haven’t been for ages.’
I suppose (so)/I guess (so): used when you agree that someone is right, but you are not happy with the situation:
‘We’ll have to get some new tyres.’ ‘I suppose so/I guess so. But it will be expensive.’
Ways of expressing disagreement:
I’m sorry, but…/Excuse me, but…/Pardon me, but…:used when politely telling someone that you do not agree with them:
Sorry/Excuse me/Pardon me, but it was never proved that he stole that car.
Absolutely not/Of course not…/Nothing of the kind! used for saying that you completely disagree with what someone has said:
‘I think I should accept the blame for the accident.’ ‘Absolutely not!/Of course not!/Nothing of the kind! There’s no way it was your fault.’
I don’t know/I take your point/That’s true, but…: used as polite ways of saying that you do not really agree with someone:
‘Peter is really unfriendly sometimes. ‘I don’t know, he’s always been very kind to me.’
‘These taxes on petrol are far too high.’ ‘Well yes, I take your point. But maybe that’ll encourage people to use their cars less.’
‘She’s a difficult person to work with.’ ‘That’s true, but she’s a really good designer.’
Speak for yourself…: an informal and sometimes impolite way of telling someone that your opinion is very different to theirs:
‘We don’t mind walking from here.’ ‘Speak for yourself! My feet are killing me!’
Don’t make me laugh/Are you kidding?/You must be joking…:informal ways of telling someone you completely disagree with them, and you think that what they have said is crazy:
‘I really think the Beatles are overrated.’ ‘Are you kidding?/Don’t make me laugh! They’re better than any of the modern bands.’
Because I am not a native English speaker I have tried to look for more easy ways to apply this words when I will come up to an expressing agreement or disagreement. At least I have tried to learn and this also made me interested because English is an international language. Who knows I could travel Amerika one day. LOL!
