Definition: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.
Don't forget to capitalize all parts of proper nouns. Many people forget to capitalize words like river and county in proper nouns like Yellow River and Orange County.
