A proper noun is a special kind of noun. When something
has its own name, the name is called a proper noun. Proper
nouns are names, nicknames, the name of your school, and the
names of the city and state in which you live.
Proper nouns start with a capital letter. Look for the
proper nouns in this sentence. Billy said he would enjoy
going to Canton, Ohio for his vacation. The proper nouns are
Billy, Canton, and Ohio.
Capital letters say, "This noun is different and
special from other nouns."
