A noun is a fundamental part of speech that represents a person, place, thing, or idea.Nouns are the building blocks of sentences and are used to identify and refer to various elements in language.
They can be categorized into common nouns (e.g., “cat,” “city”) that refer to general entities, and proper nouns (e.g., “John,” “Paris”) that identify specific individuals or places.
Nouns play a crucial role in language as they help convey meaning, define subjects and objects, and serve as the foundation for sentence structure and communication.
