What Is a Noun? A Complete Guide with Examples
A noun is one of the most essential building blocks of the English language. Whether you’re learning English for the first time or brushing up on your grammar, understanding nouns is key to forming clear, correct sentences.
Definition of a Noun
A noun is a word that names a person, place, thing, or idea.
Examples:

If you can see it, touch it, name it, or think about it—it’s probably a noun.
