Nouns and Verbs

Explanation: A Noun names the person, place, thing or idea that a sentence is а bout: the subjects and objects. A verb expresses the action performed by the subject that impacts the object, or expresses a state of being, identity or description of the nouns. Nouns may be replaced by pronouns, but the essential identity is indicated by the noun.
