Answer:
Common nouns name any person, place, thing, or idea. They are not capitalized unless they come at the beginning of a sentence. Proper nouns are the names of specific people, places, things, or ideas. Proper nouns should always be capitalized.
Explanation:
Common nouns refer to generic things while proper nouns refer to specific things. For example, the noun country is a common noun because it refers to a general, non-specific place. On the other hand, the noun Spain is a proper noun because it refers to a specific country located in Europe (another proper noun).
