In
grammatical theory, a 'noun phrase' (abbreviated 'NP') is a
phrase whose
head is a
noun or a
pronoun, optionally accompanied by a set of modifiers.
[1]
The modifiers may be:
★
determiners:
articles (''the'', ''a''),
demonstratives (''this'', ''that''),
numerals (''two'', ''five'', etc.),
possessives (''my'', ''their'', etc.), and
quantifiers (''some'', ''many'', etc.); in English, determiners are usually placed before the noun;
★
adjectives (''the 'red' ball''); or
★
complements, in the form of an
adpositional phrase (such as: ''the man 'with a black hat'''), or a
relative clause (''the books 'that I bought yesterday''').
In
English, for some purposes, noun phrases can be treated as single grammatical units. This is most noticeable in the
syntax of the English
genitive case. In a phrase such as ''The king of Sparta's wife'', the possessive
clitic "
-'s" is not added to the ''king'' who actually has the wife, but instead to ''Sparta'', as the end of the whole phrase. The clitic modifies the entire phrase ''the king of Sparta''.
Grammatical function
A noun phrase can play the role of a
verb argument (such as the
subject, the
object) or the role of the
predicate. A prototypical case is the case when the noun phrase cooccurs with the
copula and another noun phrase. The possibility for a noun phrase to play the role of
subject and predicate leads to the constructions of
syllogisms.
