What is a proper noun?

A proper noun refers to a specific person, place, or thing. Because they denote the exact name of a particular noun, they are always capitalized no matter where they fall within a sentence.

Grammar rules for proper nouns

There are several specific grammar rules for proper nouns that relate to capitalization, use of articles, directions, relationships, dates, and job titles.


  • People – A person's first, middle, and last name are considered proper nouns (or proper names) and should be capitalized. Nicknames and pet names are also proper nouns and should be capitalized.
  • Places – Specific names of locations (township, city, state, country, continent, etc.) and bodies of water (Lake Erie, Nile River, Pacific Ocean) are proper nouns. In some cases, a specific residence can function as a proper noun, such as the White House and Buckingham Palace.
  • Things – Common things that are proper nouns include company names, historical monuments, and brand names.

Only the important words are capitalized when a proper noun includes a preposition or conjunction. For example:

Fatima moved to the United States of America from Trinidad and Tobago.


The articles "a," "an," and "the" do not typically precede proper nouns.

"The" is the exception to this rule because it can precede the name of a country if that name includes "States," "Kingdom," "Republic," etc., and rivers, seas, and oceans.

“The” should not have a capital letter unless it is the first word of a sentence.

Proper noun grammar rules articles


Directions such as north, south, east, and west are only written as proper nouns if used within the name of a place.

  • Proper noun: We have family living in South America.
  • Common noun: We have family members who live in the south.

Proper noun grammar rules directions


Words indicating a family member (mom, dad, grandma, etc.) should have an initial capital letter only if the word is used the same way as an actual name. Otherwise, it should have lowercase letters.

  • Proper noun: Can you please ask Dad what time we are leaving today?
  • Common noun: His dad decided to leave early today.

If a family title precedes a name, it is a proper noun. Examples are Aunt Vicky and Uncle Ron.

Proper noun grammar rules relationships


Days of the week and months of the year are proper nouns; however, seasons are not. For example:

Seasons should only be capitalized if used as part of a specific name:

Matt and Penelope organized the Spring Fling.

Job titles

Job titles are not considered proper nouns. However, they should be capitalized if they precede a person's name.

  • President George Washington
  • George Washington was the president.

Proper noun vs. common noun

Common nouns reference general people, places, and things, whereas proper nouns are specific and exact. Due to their generic nature, common nouns are not capitalized in English.
