Grammar explanation
We can add question tags like isn't it?, can you? or didn't they? to a statement to make it into a question. Question tags are more common in speaking than writing.
We often use question tags when we expect the listener to agree with our statement. In this case, when the statement is positive, we use a negative question tag.
She's a doctor, isn't she?
Yesterday was so much fun, wasn't it?
If the statement is negative, we use a positive question tag.
He isn't here, is he?
The trains are never on time, are they?
Nobody has called for me, have they?
If we are sure or almost sure that the listener will confirm that our statement is correct, we say the question tag with a falling intonation. If we are a bit less sure, we say the question tag with a rising intonation.
Formation
If there is an auxiliary verb in the statement, we use it to form the question tag.
I don't need to finish this today, do I?
James is working on that, isn't he?
Your parents have retired, haven't they?
The phone didn't ring, did it?
It was raining that day, wasn't it?
Your mum hadn't met him before, had she?
Sometimes there is no auxiliary verb already in the statement. For example, when:
... the verb in the statement is present simple or past simple and is positive. Here we use don't, doesn't or didn't:
Jenni eats cheese, doesn't she?
I said that already, didn't I?
... the verb in the statement is to be in the present simple or past simple. In this case we use to be to make the question tag:
The bus stop's over there, isn't it?
None of those customers were happy, were they?
... the verb in the statement is a modal verb. Here we use the modal verb to make the question tag:
They could hear me, couldn't they?
You won't tell anyone, will you?
If the main verb or auxiliary verb in the statement is am, the positive question tag is am I? but the negative question tag is usually aren't I?:
I'm never on time, am I?
I'm going to get an email with the details, aren't I?

Hello Ahmed Imam,
'do you' is the correct form. The question tag refers to 'don't think', not to 'is'.

'Do you' is the answer. Consider only ' you don't'.
Where do we have to use the 'do' forms?
She is a teacher
She has a car
He needed a pen
Hello Abhi1999,
I assume you mean when is 'do' needed in the question tags for these sentences. You have to look at the tense of the verb in each sentence. If the tense is present simple or past simple, you need to use 'do/does' (for present simple) or 'did' (for past simple). In 2, 'has' is present simple, so the question tag is 'doesn't she?' and in 3 'needed' is past simple, so the tag is 'didn't he?'.
There is one exception to this rule: when the verb is 'be', we don't use 'do/does/did' to make the question tag. Instead we just use 'be' in the negative. So for 1, the tag is 'isn't she?'.
Hope that helps.
All the best,

Hi team,
Can you tell me what is the tag of "I wish to study English better,.............?" and "She wishes to go to Singapore,..........?"
Thanks so much!
Hello TracyHoang,
Perhaps I'm just not imagining the situation correctly, but it seems a little strange to use a question tag in the first sentence because it means the speaker is questioning their knowledge of their own wishes. Also, the verb 'wish' is rather formal for this kind of sentence. But I suppose you could say 'don't I?' here.
The second one is also a little strange because of the formality of 'wish' as a verb. But here it is affirmative and in the third person, so the tag is 'doesn't she?'
All the best,

When we use the verb to be with the pronoun I we know it's correct to say: I am your teacher, aren't I?
What about the past tense of the verb to be?
We say I was your teacher, wasn't I? or we say I was your teacher, weren't i?
Thanks in advance
Hello janemorgan,
The reason we use aren't I in first-person tag question is quite simple: it would be almost impossible to pronounce *amn't I!
We can see that it's really a question of pronunciation because when we use the tag in a non-contracted form, which is possible if rather theatrical and pompous-sounding, we actually say am I not.
The past form is easier: we use was just as in any first-person form (wasn't I).

Hi!
Could you help me with this ?which one is correct?
They explained that she couldn't take the course,didn't they/couldn't she ?
I'm actually not sure which clause will refer to the tag
Thanks
Hello Faii,
The tag refers to the main clause ('They explained'), so the correct one is 'didn't they?'.
All the best,
