Nouns are naming words. Everything we see or are able to talk about is represented by a word which names it - that word is called a 'noun'.
A noun is a part of speech that is used to name a person, place, thing, quality, or action.

Generally, the purpose of a sentence is to provide information about or give instructions to a person, animal, place or thing.
