Quick Summary

A noun phrase is a group of words that functions like a noun in a sentence. It typically consists of a noun and any words that modify it, such as articles or adjectives. For example, in the sentence "The big dog barked," "the big dog" is a noun phrase, with "dog" being the noun and "the" and "big" acting as modifiers. Noun phrases can serve as the subject of a verb or the object of a verb or preposition. They are a fundamental building block in sentence structure.12
