5. Pronunciation of question tags

Commonly, question tags are pronounced with a falling or a rising intonation.

A falling tag like "↘isn't it?" "↘don't you?" and "↘won't they?" indicates that the speaker is not really asking, more telling the listener that their statement is correct. They're very common at the end of any statement:

It's raining, ↘isn't it?
David can't speak French, ↘can he?
Sarah came by car, ↘didn't she?

Falling tags can be used to gently persuade the listener:

We're going to Anne's party, ↘aren't we?
You won't forget to do your homework, ↘will you?
You've brought the money, ↘haven't you?

A rising tag is really a question, the listener is being urged to respond with their input, using the same examples, notice the difference in meaning:

It’s raining, ↗isn’t it?
David can’t speak French, ↗can he?
Sarah came by car, ↗didn’t she?

Other question tags include Imperative and Suggestion tags, these are always pronounced with rising intonation:

• An imperative statement can be followed by a rising tag question. Many modal verbs can be used here for varying levels of politeness:

Pass me the butter, ↗will you?
Pick me up in half an hour, ↗would you?
Open the window, ↗could you?

• A suggestion can be followed by a rising tag using ‘shall’:

Go for a walk, ↗shall we?
I’ll make some biscuits, ↗shall I?
Let’s visit Italy this year, ↗shall we?
