Proper nouns are nouns that identify specific individuals, places, things, or ideas. Proper nouns are always capitalized. A proper noun can be either singular or plural.
Some examples of proper nouns are John, Mary, George, and Sarah. Other examples are the Statue of Liberty, the Brooklyn Bridge, and the Brooklyn Dodgers.
A proper noun always has a specific unique name. It cannot be used as a common noun. For example, you cannot say “John’s book” or “Mary’s bag.”
There are important rules for using proper nouns:
- Proper nouns must always be capitalized.
- Proper nouns must always be used in their specific, unique form. For example, you cannot say “John’s house” or “George’s car.”
