A noun phrase is a substantive phrase which amounts to a noun or noun substitute in function. It may contain a single noun, or it may comprise some other grammatical class of words such as adjective phrases, prepositional phrases, possessive phrases, or entire clauses.
Noun phrases can also be used for qualification (as in the case of an attributive adjective phrase), determination (as in the case of a determinative phrase), or quantification (as in the case of a numeral phrase or a quantifier phrase).
