Question tags (tag questions)

Question tags

question_tagsQuestion tags (also called tag questions) are common structures used in spoken English.

An example of a question tag is: ‘You like studying English, don’t you?’

The first part of a question tag sentence is the statement (‘You like studying English’) followed by the question form (‘don’t you?’)

It is important to note that question tags are generally not questions at all – they are used for the following purposes:

1. To confirm information you are think you know (e.g. ‘Your birthday is in May, isn’t it?’ = I think your birthday is in May, but can you confirm that)

2. To act as a conversation starter (e.g. ‘You bought their new album, didn’t you? What did you think of it?’)

3. To ask for agreement with something (e.g. ‘You believe me, don’t you?’)

When question tags are used as real questions, we often begin with the negative. Compare:

Not a real question A real question
It’s a lovely day, isn’t it?You’ve been here before, haven’t you? ‘You haven’t seen my keys, have you?”You don’t know where the bank is, do you?’

Another important difference between question tags used as real questions versus question tags that are not real questions is the sound of your voice.

For example:

REAL QUESTION: You haven’t seen my keys, have you? (the tag has a rising intonation – the sound of your voice goes up)

NOT A REAL QUESTION: It was an exciting game, wasn’t it? (the tag has a falling intonation – the sound of your voice goes down)

Forming question tags

The ‘tag’ part of the structure comes from copying the auxiliary verb in the main statement. For example: You haven’t seen my keys, have you? You are from New Zealand, aren’t you?

If there is no auxiliary verb, then the verb ‘do’ is used: You like ice cream, don’t you? The table below shows the formation of most question tags.

Subject Auxiliary verb Main verb (Additional info) + comma Auxiliary Match subject Question mark
He is studying hard, isn’t he ?
They have missed the bus, haven’t they ?
They have a car, don’t they ?
She will come to the party, won’t she ?
John could meet us, couldn’t he ?
The doctor should be able to help, shouldn’t she ?
You can speak French, can’t you ?


Question tags – Exceptions Some question tags are unique in that they don’t fit into the table above. Here are some of the more unusual tags that are exceptions to the rules:

  • Let’s go, shall we?
  • I am late, aren’t I?
  • Nobody telephoned you this morning, did they? (tag is positive when statement has ‘nobody’, ‘nothing’)

Be careful when answering a tag question! Consider the following: A: London isn’t in Spain, is it? B: Yes (meaning ‘I agree with what you said’) Incorrect You cannot say this A: London isn’t in Spain, is it. B: No (Meaning ‘London is not in Spain’) Correct This is correct
