We have now completed
the first level of grammatical analysis, in which we looked at words individually
and classified them according to certain criteria. This classification is
important because, as we'll see, it forms the basis of the next level of
analysis, in which we consider units which may be larger than individual
words, but are smaller than sentences. In this section we will be looking
at PHRASES.
Defining a Phrase When we looked at nouns and pronouns, we said that a pronoun can sometimes replace a noun in a sentence. One of the examples we used was this: Here it is certainly true that the pronoun they replaces the noun children. But consider: In this example, they does not replace children. Instead, it replaces the children, which is a unit consisting of a determiner and a noun. We refer to this unit as a NOUN PHRASE (NP), and we define it as any unit in which the central element is a noun. Here is another example: In this case, the pronoun it replaces not just a noun but a five-word noun phrase, the title of your book. So instead of saying that pronouns can replace nouns, it is more accurate to say that they can replace noun phrases. We refer to the central element in a phrase as the HEAD of the phrase. In the noun phrase the children, the Head is children. In the noun phrase the title of your book, the Head is title. Noun phrases do not have to contain strings of words. In fact, they can contain just one word, such as the word children in children should watch less television. This is also a phrase, though it contains only a Head. At the level of word class, of course, we would call children a plural, common noun. But in a phrase-level analysis, we call children on its own a noun phrase. This is not simply a matter of terminology -- we call it a noun phrase because it can be expanded to form longer strings which are more clearly noun phrases. From now on in the Internet Grammar, we will be using this phrase-level terminology. Furthermore, we will delimit phrases by bracketing them, as we have done in the examples above.
