Tag questions are statements followed by a mini-question, called a question tag, that is used to guide the answer in the direction wanted. The basic structure is a positive statement followed by a negative question tag, or a negative statement followed by a positive question tag. The question tag uses the same verb as the main statement, whether it is an auxiliary verb like "have" or "be", or "do" if there is no auxiliary. Modal verbs in the statement are also used in the question tag. A statement starting with "I am" takes "aren't I?" as the question tag.

the sentence. If this is an auxiliary verb (‘have’, ‘be’) then
the question tag is made with the auxiliary verb.

5. Without auxiliary verbs
If the main part of the sentence doesn’t have an auxiliary
verb, the question tag uses an appropriate form of ‘do’.
