Use

Tag questions are used to check for information.

Positive statements are followed by negative tag questions.

• He is here, isn’t he?

Negative statements are followed by positive tag questions.

• He can’t go, can he?

Example:

We are leaving today, aren't we?

Explanation:

The tag question aren’t we is added to the sentence to ask for confirmation. The speaker thinks that they are ‘today’, and is checking to see if the information is true.

How to build

Tag questions are added at the end of sentences, and come after a comma.

To make a tag question for a sentence with present simple tense or past simple tense we use:

do/does/did + the subject of the sentence.

• She likes it, doesn’t she?

• She liked it, didn’t she?

To make a tag question for a sentence with the verb ‘to be’ we use:

am/is/are + the subject of the sentence.

• You are ready to go, aren’t you?

To make a tag question for a sentence with modal verbs we use:

modal verb + the subject of the sentence.

• You won’t bring it, will you?

• He can tell us, can’t he?
