yes and no
Answers to negatives
In English, yes is used with affirmative sentences and no with negative sentences. In answers to negative questions and statements, yes and no are chosen according to the form of the answer, not in order to show agreement or disagreement with the speaker.
- ‘Aren’t you going out?’ ‘No, I’m not.’ (not
Yes, I’m not.) - ‘I have no money.’ ‘No, I haven’t either.’ (not
Yes, I haven’t too.) - ‘Haven’t you got a raincoat?’ ‘Yes, I have.’ (not
No, I have.)
Contradicting
Some languages have a special word for contradicting negative statements or suggestions (e.g. French si or German doch). English does not have a word like this. We often use a short answer structure (see here).
- ‘The phone isn’t working.’ ‘(Yes,) it is.’ (not
‘The phone isn’t working.’ ‘Yes.’)
Affirmative sentences are contradicted with negative short answers.
- ‘It’s raining.’ ‘(No,) it isn’t.’
