Step-by-step explanation:
A noun is refered to as a word that is used to name something, which can be a person, place, or thing. Examples of noun are Tom, London, dog, cat etc.
Nouns are important to communication as they refer to different things. Without nouns, we'll only have adjectives, verbs etc and this will make effective communication impossible.
The lack of nouns will lead to the eradication of the subject or object and this will make a sentence incomplete and communication impossible.
