A noun phrase is either a single noun or pronoun or a group of words containing a noun or a pronoun that function together as a noun or pronoun, as the subject or object of a verb.
Examples:-Appositive Phrase
An appositive (single word, phrase, or clause) renames another noun, not technically modifying it.
Example:
“Bob, my best friend, works here” or “My best friend Bob works here.”
-Gerund Phrase
A gerund phrase is just a noun phrase with a gerund as its head.
Example:
“I love baking cakes.”
-Infinitive Phrase
An infinitive phrase is a noun phrase with an infinitive as its head. Unlike the other noun phrases, however, an infinitive phrase can also function as an adjective or an adverb.
Example:
“I love to bake cakes.”
In simple words, a verb of more than one word is called a verb phrase. It is a phrase consisting of a verb, its auxiliaries (helping verbs), its complements, and other modifiers. Auxiliary verbs always come before the main verb. A verb phrase is a syntactic unit that corresponds to the predicate. There are two types of auxiliary verbs. Inflected auxiliary verbs e.g. be, have, do and Modal auxiliary verbs e.g. will, should, must etc.
