Question tag is a short question that we put at the end of statement. It is usually used to:
- confirm that something is true or not
- encourage a reply from the person we are speaking to
The rules are very simple:
- If the main part of the sentence is positive, the question tag is negative
- positive statement --> negative tag
- If the main part of the sentence is negative, the question tag is positive
- negative statement --> positive tag
Examples:
A positive statement is followed by a negative question tag.
- Sam is from India, isn't he?
- Roy can help, can't he?
- We are traveling to Switzerland next month, aren't we?
A negative statement is followed by a positive question tag.
- He shouldn't say things like that, should he?
- You haven't contacted her, have you?
- Our family wont agree with this, will they?
