Tag questions
Form
auxiliary verb + subject
1. We use the same auxiliary verb in the tag as in the main sentence. If there is no auxiliary verb in the main sentence, we use do in the tag.
o You live in Spain, don’t you?
2. If the auxiliary verb in the sentence is affirmative, the tag is negative.
o You’re Spanish, aren’t you?
3. If the auxiliary verb in the sentence is negative, the tag is affirmative.
o You’re not Spanish, are you?
Meaning
1. We use tag questions to confirm or check information or ask for agreement.

o You can swim, can’t you?
o You don’t know where the boss is, do you?
o This meal is horrible, isn’t it?

2. We use tag questions to check whether something is true.
