Tag questions

Tag questions (question tags) are short yes-no questions tagged onto the end of a statement or command. We shall consider their intonation at this point, even though they of course dependent rather than independent intonation phrases.

Most tag questions can be said either with a fall or with a rise, and there is an important difference of tone meaning between these two possibilities.

Yes-no rise

If a tag question is genuinely asking for information, the tone will be a yes-no rise. This allows the speaker to check whether the other person agrees with what he or she has just said. It is open to the other person to agree or disagree:

They ▸haven't for⤵gotten, | ⤴have they? (= Can that be the reason they're not here?

〉 ▸What does ⤵chaise mean?
》 Chair, | ⤴doesn't it?
〉 ▸Where are they going to⤵morrow?
》 ⤵Leicester, | ⤴aren't they?)

Insistent fall

The other possibility is an insistent fall. With a falling tag the speaker insists assumes or expects that the other person will agree. Rather than genuinely asking for information, the speaker appeals for agreement:

▸Seven ▸fives are ▸thirty−five, | ⤵aren't they? (= You know they are.)
Well it's ▸not very ⤵⤴good, | ⤵is it? (= You'll agree it's not very good.)
In some cases the falling-tone tag has the force of an exclamation. Exclamations always have a fall (see
2.17
):

Notice the difference of tone meaning in the following examples:

The effect of a tag with an insistent fall can even be to force the other person agree. It becomes a way of exercising control:

Constant-polarity

Most tags, as in the examples given so far, reserve the polarity of the clause to which they are attached: that is, if the main clause is positive, the tag is negative; whereas if the main clause is negative, the tag is positive (see

4.10
). Another kind of tag is the constant-polarity tag. Here the main clause is positive and the tag is also positive. Constant-polarity tags, if they have their own tone, always have a rise:
It's ⤵snowing, | /is it? (⤵Oh, | I ⤵see.)
So you ▸think you'll ⤵win, | ⤴do you? (⤵⤴I don't think you will.)

Tag attached to clause types other than statements

Tag attached to clause types other than statements are more restricted in their possibilities. When attached to an exclamation, a tag virtually always has an insistent fall:

When attached to a command, a tag often comes in the tail (with a rising tone) rather than having its own intonation phrase (see
4.10
): If the tag after a command does have its own IP, the tone is usually an encouraging rise, giving a softening effect:
▸Come over ⤵here a minute, | ⤴will you?
▸Open the ⤵window, | ⤴would you, please? (= 'Would you open the ⤴window?)
After a command, a tag with a fall sounds very insistent. Not all speakers find this construction intonationally well-formed:
▸Answer the ⤵phone, | ⤵will you? (= ▸Will you answer the ⤵phone.|| O'bey me im⤵mediately.)
Tag questions are sometimes included as parentheses within a statement. Usually they have an insistent fall, though a yes-no rise is also possible:
We 'find it ⤵difficult, | ⤵don't we, | to 'live a virtuous ⤵life. (= I'm sure you agree.)
We 'find it ⤵difficult, | ⤵don't we, | to 'live a virtuous ⤵life (= Or am I wrong?)
