It's not easy to describe a noun. In simple terms, nouns are "things" (and verbs are "actions"). Like food. Food (n) is something you eat (v). Or happiness. Happiness (n) is something you want (v). Or human being. A human being (n) is something you are (v).

These pages explain more about the grammar of nouns and offer example sentences, quizzes and songs.
