Answer with explanation:

Before we find out what is a noun phrase, first let's separate the word "noun" and "phrase" and find the definition of each word. A noun is a word that generally functions as the name of a specific object or set of objects, such as living creatures, places, actions, qualities, states of existence, or ideas whilst a phrase is a small group of words standing together as a conceptual unit, typically forming a component of a clause. Then we combine the definitions of "noun" and "phrase" to a single definition of "noun phrase". So a noun phrase is a phrase that has a noun or pronoun as its head or performs the same grammatical function as a noun.
