Common Nouns Definition and Examples
A common noun is a general name for a person, place, thing, or idea. Unlike proper nouns, which name specific people or places (like John or Paris), common nouns are general and not capitalized unless they start a sentence.
Examples:
- People: teacher, doctor, student
- Places: school, park, city

Common nouns do not refer to one unique entity but to a general class of objects, people, or concepts.
