Learning Objective
By the end of this page, you will be able to identify common nouns in a sentence and distinguish them from proper nouns based on capitalization and specificity.
What is a Common Noun?
A common noun is a generic name for a person, place, thing, or idea. Unlike proper nouns, common nouns do not refer to a specific, unique entity. They are the most frequent type of noun used in English.
Common vs. Proper Nouns
The easiest way to identify a common noun is to see if it is naming a general category rather than a specific name.
| Common Noun (General) | Proper Noun (Specific) |
|---|---|
| country | Australia |
| teacher | Mr. Smith |
| smartphone | iPhone |
| restaurant | McDonald’s |
| month | January |

Pro-Tip
The Capitalization Rule
Common nouns are only capitalized if they are at the beginning of a sentence. If a noun is capitalized in the middle of a sentence, it is likely a Proper Noun.
- Correct: The dog is hungry.
- Correct: Dogs are loyal animals.
- Incorrect: I saw a Dog in the park.
