Step-by-step explanation:
In English grammar, noun phrases are groups of words that function as nouns in a sentence. A noun phrase typically includes a noun and any modifiers or determiners that come before or after it. For example, in the sentence 'The big brown dog chased the ball,' 'the big brown dog' is a noun phrase.
An adjective is a word or phrase that describes or modifies a noun or pronoun. In the sentence 'She wore a beautiful dress,' 'beautiful' is an adjective that describes the noun 'dress.'
A verb is a word that describes an action, occurrence, or state of being. In the sentence 'He sang a song,' 'sang' is a verb that describes the action of singing.
An adverb is a word that describes or modifies a verb, adjective, or other adverb. In the sentence 'She ran quickly,' 'quickly' is an adverb that describes the verb 'ran.'
