A NOUN PHRASE IS A GROUP OF WORDS THAT DOES THE WORK OF A NOUN:

A noun phrase is a made up of a noun and all its modifiers. It can function in a sentence as a subject, an object, or a complement. Some noun phrases begin with an infinitive (to go) or a gerund (going); this type of noun phrase is always singular:

To sail the seven seas was her lifelong dream. (subject)
Dieters prefer green salad. (object)
A ham sandwich is a popular lunch. (complement)


1. The boy wants something.
2. The boy wants to go home.

The word something is a Noun and it is the Object of the verb wants , in sentence 1. Similarly the group of words,” to go home “ is the Object of the verb wants in sentence 2. Hence this group of words does the work of a Noun. The group of words to go home is therefore a Noun Phrase.
