Sentence structure

Noun phrases

A noun phrase is a group of words built around a noun (or pronoun) that together function as a single unit in a sentence, such as a subject, object or complement. It can be just one word ("dogs") or a longer group with modifiers, like "the three loud dogs next door", but it always centres on a head noun.

Types of noun phrases

Single-word noun phrase

A noun phrase made of just the head noun or pronoun with no modifiers.

e.g. Music helps me relax., She left early.

Determiner + noun

A noun phrase with an article, possessive or quantifier before the head noun.

e.g. the report, her opinion, some students

Noun phrase with pre-modifiers

Adjectives, participles or other nouns placed before the head noun to describe it.

e.g. a well-designed system, rising energy costs, the government's new policy

Noun phrase with post-modifiers

Prepositional phrases, relative clauses or infinitives placed after the head noun to add detail.

e.g. the man in the grey suit, a book that changed my life, the need to act quickly

Coordinated noun phrase

Two or more noun phrases joined by a conjunction to form one larger unit.

e.g. bread and butter, teachers, parents and students

Rules to remember

  • Every noun phrase must have a head noun or pronoun that the rest of the phrase describes or limits.
  • Determiners (a, the, this, my, some) usually come first in the phrase, before any adjectives.
  • Adjectives and other pre-modifiers go directly before the head noun, while prepositional phrases and relative clauses follow it.
  • A noun phrase can function as a subject, direct object, indirect object, subject complement or object of a preposition.
  • The verb must agree with the head noun of the subject noun phrase, not with a noun inside a modifying phrase.
