What is a noun?

A noun is fundamentally defined as a word that names a person, place, or thing. Nouns are critical components of sentence structure, as they allow us to identify subjects and objects within communication. This definition encompasses a broad range, including concrete nouns like "apple" or "city," and abstract nouns such as "happiness" or "freedom." Understanding nouns is essential for constructing clear and meaningful sentences, as they serve as the building blocks of our language, indicating who or what we are referring to in our discourse. Recognizing this foundational aspect of grammar helps in both written and verbal communication.
