This section discusses the postmodification of nouns. Postmodifiers of nouns usually take the form of an adpositional phrase or a clause. Adpositional postmodifiers are discussed in Section 17.3.1. Clausal postmodifiers come in various forms, but most often take the form of a finite relative clause or an infinitival construction, which will be discussed in Sections 17.3.2 and 17.3.3, respectively. Section 17.3.4 discusses a special case of postmodification involving restrictive postmodifiers of content nouns, which can be seen as the counterpart of the complement clauses of these nouns discussed in Section 16.3. Sections 17.3.5 and 17.3.6 conclude with a discussion of the use of adjectival and adverbial phrases as postmodifiers.
