Noun

In grammar, a noun is a word that represents a concrete or abstract thing, like living creatures, places, actions, qualities, states of existence, and ideas. A noun may serve as an object or subject within a phrase, clause, or sentence. In linguistics, nouns constitute a lexical category (part of speech) defined according to how its members combine with members of other lexical categories.
