I'm sure you remember learning that nouns could be a person, place, or a thing. Nouns can also be singular or plural. But, in general, nouns don't get capitalized unless they are the first word of a sentence. Why do other nouns, like "Bank of America," get capitalized no matter where they are in the sentence? That's because it's a proper noun is the specific name of a person, place, or a thing. Let's look a few examples.
Noun: country
Proper noun: Canada
Noun: city
Proper noun: Hollywood
Noun: teacher
Proper noun: Mrs. Jones
Noun: police officer
Proper noun: Captain Harold Cornwall
Noun: soda
Proper noun: Pepsi
Noun: company
Proper noun: Sony
Now it's your turn. Please write two sentences. One sentence should use a regular (general) noun; the next sentence should use a proper noun representing that same thing. An example is below.
I bought the newspaper at the store. The Sun-Sentinel is my favorite publication.
(My regular noun was "newspaper" and my proper noun was "Sun-Sentinel," which is the name of a specific newspaper.)
