What Is a Proper Noun?

A proper noun is the specific name of a particular person, place, thing, or idea. Unlike common nouns, which name general categories, proper nouns name one specific member of that category.

The rule: Proper nouns are always capitalized - no matter where they appear in a sentence.

girl: Emma

city: Seattle

river: Mississippi River

dog: Biscuit

school: Lincoln Elementary

holiday: Thanksgiving

month: October

day: Friday

Common Noun vs. Proper Noun

Here's the key question: Is this one specific thing, or is it a general category?

mountain is a common noun - it refers to any mountain in general
Mount Everest is a proper noun - it refers to one specific mountain
teacher is a common noun - it refers to anyone who teaches
Mrs. Rodriguez is a proper noun - it refers to one specific teacher
book is a common noun - it refers to any book in general
Charlotte's Web is a proper noun - it refers to one specific book

Capitalization Rules for Proper Nouns

Every significant word in a proper noun is capitalized:

Golden Gate Bridge (not Golden gate bridge) Pacific Ocean (not Pacific ocean) New York City (not New york city)

Small connecting words (of, the, and) within a proper noun are usually lowercase:

Statue of Liberty Museum of Natural History

Titles before names are proper nouns and are capitalized:

Dr. King, President Washington, Coach Miller

Titles used alone (without a specific name) are usually common nouns and are not capitalized:

"I saw the president on TV." (no specific name) "I saw President Biden on TV." (specific name → proper noun)
