Question tags

We use tags in spoken English but not in formal written English.

They are not really questions but are a way of asking the other person to make a comment and so keep the conversation open.

Making a tag is very mechanical. To make a tag, use the first auxiliary. If there is no auxiliary, use do, does or did. With a positive sentence, make a negative tag and with a negative sentence, make a positive tag.

• It's beautiful, isn't it?
• He has been, hasn't he?
• You can, can't you?
• It must be, mustn't it?
• You know him, don’t you?
• He finished it, didn't he?
• He will come, won't he?

• It isn't very good, is it?
• It hasn't rained, has it?
• It can't be, can it?
• Jenny doesn't know James, does she?
• They didn't leave, did they?
• He won’t do it, will he?

Notice these:

• There isn't an ATM here, is there?
• Let's have a cup of coffee, shall we?

To reply, use the same auxiliary:

• It's beautiful, isn't it? ~ Yes, it is. I think it's fabulous.
• It isn't very good, is it? ~ No, it isn't. In fact, it's terrible.

Although, the rules are very simple and mechanical, in order to use them easily in conversation, they have to be automatic. So you need to hear and practice them very often.
