Question tags are small questions "tagged" on to the end of a sentence to make a question. For example

Sentence:- She speaks English

Question:- Does she speak English

?Question Tag:- She speaks English, doesn't she


Form

Question tags are made from an auxiliary verb and the subject

If the sentence is affirmative, we usually use a negative tag, for example

? That's a great song, isn't it

? She's a lawyer, isn't she

If the sentence is negative, the tag is positive. For example

?You're not busy, are you

? This way isn't right, is it

The auxiliary verb and subject in the question tag match those in the main sentence. Only the positive and negative past changes

For example

? He can play the trumpet, can't he

? You haven't finished yet, have you

Here the subject is in blue, and the auxiliary verb in green. It's just whether each part of the question is positive or negative that changes


Function


Question tags have two main purposes: to confirm expected

information and to question unexpected information. You can tell

which function is being used by the voice - when the voice goes

down it's checking expected information - when the voice goes up

it's really asking a question. For example

?Intonation going down - You haven't finished yet, have you

I expect you haven't finished, I'm just checking

? Intonation going up - You haven't finished yet, have you

I'm really asking if you're finished or not. If you are finished it's earlier than I expected, so I'm surprised

You're really busy now, aren't you? - Yes, I've got to finish this by Monday

I'm confirming you're busy now, possibly showing sympathy as well

?Why are you watching TV? You're really busy now, aren't you

Not really, I did most of it last nightI think you're busy but I'm

surprised, you should be working not watching TV, so I'm asking about an unexpected situation

Negative sentences with positive tags are often used for requests

for example


? You don't have a pencil, do you

? You couldn't change a $5 bill, could you

Imperative questions tags usually use will, for example

?Open the door for me, wil you

? Hang on a minute, will you

Unless used with informal language, question tags with

imperatives can often sound impatient

Question tags are an important part of natural speech and are

particularly useful in small talk, as they help to confirm and affirm

key information in a sympathetic way
