Empty words and pro-forms
There are various categories of word and phrase that tend not to receive the nucleus, even though they may be the last lexical item in the IP.
A
Some nouns, for example, have very little meaning on their own: particularly vague general nouns such as things, people. Such empty words are usually not accented.
They're ▸really 'going places.
▸What are you going to 'say?
They're ▸really 'successful.)
B
Sometimes expressions such as the man, that woman, etc. mean little more than he, she. Like pronouns, therefore, they are not accented when used in this way:
I ▸can't 'stand that woman. (= I ▸can't 'stand her.)
C
There are several idiomatic expressions in which some is accented (often bearing a fall-rise nuclear tone), while the following noun is not. (The same pattern is lexicalized in the word 'sometimes and various other words beginning some-.)
In ⤵⤴some cases, | the answer is obvious.
⤵⤴Some days | I feel very depressed.
D
Numerals (one, two, three...) tend to be accented, since they have considerable semantic content. However, when one is used as a pronoun - a pro-form, a kind of function word - it is not accented and so does not take the nucleus:
I've got ▸lots of 'milk left, | ▸would you 'like some?
Would you like a 'green one | or a 'red one
(to someone who has just picked up a key) Have you ▸got the right 'one?
E
The word so is normally not accented when it is used as a pro-form (to refer back to an idea, situation, etc. that has just been mentioned):
〉 Is he ▸still going to 'college?
》 I 'think so.
E
As we saw above, when a form of do is used as a pro-form (= as a substitute for another verb), it is not accented:
'Peter smokes, | and his 'sister does, | 'too.
〉 ▸Will you go to 'Brighton tomorrow?
》 I 'may do.
F
Likewise, there is usually not accented when used as pro-form.
