In a sentence, sometimes more than one word is required to explain the subject. When some words come together before a noun, to explain the noun better, the group of words is called a Noun Phrase. A noun phrase does exactly the work of a noun.
The subject "mango" is described as:
A mango.
A sweet mango.
A sweet Alphonso mango.
A ripe sweet Alphonso mango.
A big, ripe, sweet Alphonsomango.
