Some examples of nouns include "flower," "dog," "president," "country," "mountain," "Mary," "California," "France," "George Washington" and "Mount Everest." "Flower," "dog," "president," "country" and "mountain" are examples of common nouns, while "Mary," "California," "France," "George Washington" and "Mount Everest" are examples of proper nouns.
It is important to distinguish between common nouns and proper nouns. Common nouns refer to a generic, unspecific person, place, thing or idea. Proper nouns, on the other hand, refer to a specific person, place, thing or idea. Common nouns are never capitalized, while proper nouns are always capitalized.
As an example, the following sentence contains both a common noun and a proper noun: "My favorite book is 'The Old Man and the Sea.'" The word "book" in this example sentence is a common noun because "book" is an unspecific word that can refer to any number of books. However, "The Old Man and the Sea" is a proper noun because it refers to a specific book. Other examples of proper nouns include the names of cities, such as San Francisco or Cairo, the names of days of the week, such as Saturday and Sunday, and the names of holidays, such as Thanksgiving and New Year's Eve.
