Proper Noun: Definition, Rules and Examples of Proper Nouns

Last Updated on November 14, 2023

There are various types of nouns within the English language, and one such type is the proper noun. When using proper nouns it is important to follow the correct rules to make a sentence that has meaning, structure and above all, makes sense. In this article, we are going to be looking at what a proper noun is and how it can be used within a sentence. We will also be looking at some examples to further demonstrate their function.

What Is A Proper Noun?

Proper Noun: Definition, Rules and Examples of Proper NounsPin

A proper noun may also be referred to as a proper name. It is a noun which refers to a specific person or place. This could be the name of a person or a country, for example.

Examples of proper nouns include names of people, like Serena Williams or Joyce, geographical locations, such as São Paulo or Seattle, and titles of books, movies, songs, and other media, like Lord of the Rings or the Empire State Building. In these cases, the capitalization sets proper nouns apart from their common noun counterparts like “athlete”, “city”, and “building”.

The use of proper nouns during spoken conversation is not often considered to be important because the syntax is not affected, however, when we use a proper noun within our written work, it is important to ensure the correct use of capital letters. One important thing to remember when using a proper noun is that the first letter should ALWAYS be a capital. Let’s look at some examples of the proper noun.

  • Pride and Prejudice
  • John Doe
  • The Eiffel tower
  • Australian Outback

As you can see, all of these proper nouns refer to a specific thing rather than their common noun counterparts which would be a book, a man, a building or a place. By using a proper noun, you are able to give more information about the specific thing you are talking about.

Rules for The Proper Noun

As with all areas of English grammar, there are certain rules which should be followed when using a proper noun. We are now going to take a look at these rules so that you can feel confident that your grammar will always be correct.

Capitalising The Proper Noun

In many cases, capitalizing proper nouns is straightforward. For example, when referring to a specific person like Serena Williams, a place like Australia, or an organization like United Nations, the words should be capitalized.

When it comes to directions and regions, capitalization rules may vary. Cardinal directions (north, south, east, and west) are not capitalized when used as general directions or locations. However, the same words are capitalized when they refer to specific regions. For instance:

  • The weather is colder in the north. (general direction)
  • The Northern lights are a phenomenon in the Arctic region. (specific region)

The first word of a sentence is always capitalized, as well as the first word of a quotation and the first word after a colon, but only when it introduces a complete sentence. For example:

  • She said, “Tomorrow I’ll be visiting London.”
  • Life has two rules: Never quit, and always remember Rule Number 1.

Common nouns, unlike proper nouns, do not require capitalization unless they are the first word in a sentence or part of a title.

Proper Nouns in Relationships

Despite the proper noun requiring a capital letter, there are, of course, exceptions to the rule. Let’s take the use of family relationships as a proper noun, for example, dad, mom, grandma, etc. These words can be nouns but can also be used as a proper noun when you are using them to refer to someone by name. For the latter, they should be capitalised. Let’s look at some examples.

  • Please can you tell Dad that I have gone to my friend’s house?
  • My friend’s dad is a very nice guy.

The first example shows the word dad being used as a proper noun and so is capitalised, however in the second example, it is not.

Directions As Proper Nouns

The directions, as seen on a compass should only take a capital letter if they are being used as a place name. Here are some examples of this.

  • My aunt lives in South Korea.
  • My aunt lives in the south of Korea.

The first example uses the word south as a part of a place name and so is a proper noun, however, the second example uses it as a description of the location and so is not classed as a proper noun.

Things That Do And Don’t Need To Be Capitalised

It is sometimes difficult to determine what is a proper noun and therefore needs to take a capital letter, and what does not. Here are some examples of things that do and do not need to take a capital letter.

Capital Letter

  • Brand names
  • Weekdays
  • Month names

No Capital Letter

  • Seasons of the year
  • Job titles

Proper Nouns with or without Articles

Using Articles with Proper Nouns

In general, articles are not used with proper nouns. However, there are some exceptions to this rule. Here are some guidelines to follow when using articles with proper nouns:

  • Use “the” with a proper noun when it refers to a specific entity that is unique or has a particular identity. For example, “the Eiffel Tower,” “the White House,” “the Amazon River.”
  • Use “a” or “an” with a proper noun when it is being used as a common noun, to refer to a class of things. For example, “a Picasso,” “an Einstein,” “a Ferrari.”
  • Use “the” with a proper noun when it is being used as a common noun to refer to a group of people or things. For example, “the Beatles,” “the Kennedys,” “the Simpsons.”

Not Using Articles with Proper Nouns

In general, proper nouns do not require articles. However, there are some exceptions to this rule. Here are some guidelines to follow when not using articles with proper nouns:

  • Do not use articles with proper nouns that are names of people, places, or things. For example, “John Smith,” “New York City,” “Mount Everest.”
  • Do not use articles with proper nouns that are used as titles or names of organizations. For example, “President Biden,” “Apple Inc.,” “United Nations.”

Nouns That Can be Either Proper or Common

In the English language, there are instances where a noun can function as both a proper and a common noun. Identifying these dual-purpose nouns is crucial for proper capitalization and usage in sentences.

One common example is when a noun represents a brand or company name but also symbolizes an entire product category. A few illustrations of these instances are:

  • Kleenex is a proper noun, as it is a brand name for facial tissues. However, it has become synonymous with the product itself, making it also a common noun.
  • Google is a search engine company, classifying it as a proper noun. Yet, the act of searching online has become known as “googling,” making it a common noun as well.

Some other examples in which the line between proper and common nouns blurs include the following:

  • Coke for all types of cola drinks, beyond just Coca-Cola branded beverages.
  • Aspirin which was originally a trademark name for a specific pain reliever but has since evolved into a common noun for all similar pain relievers.

Another scenario where the dual role occurs is in certain job titles or positions. For instance:

  • President can be a common noun for referencing a leader, but it transforms into a proper noun when specifying a specific person, such as President Biden.

It is essential to note that the context and capitalization play crucial roles in differentiating between the two forms. As a general rule, proper nouns require capitalization, while common nouns do not, unless they begin a sentence.

Frequently Asked Questions

What are the main differences between common and proper nouns?

Certainly. Here are some examples of proper nouns across different categories:

What are some common rules for capitalizing proper nouns?

Proper nouns follow specific capitalization rules in English. The main rule is that the first letter of a proper noun must always be capitalized. However, there are additional rules and guidelines to consider, such as:

  • When a proper noun consists of multiple words, each word should be capitalized (e.g., Golden Gate Bridge).
  • Titles and honorifics followed by a name should be capitalized (e.g., Dr. Johnson, Queen Elizabeth).
  • Acronyms and abbreviations for proper nouns should also be capitalized (e.g., NASA, FBI).

Can proper nouns be plural?

Yes, proper nouns can be plural. For example, the proper noun “Smith” can become “the Smiths” when referring to a family with that last name. However, the plural form of a proper noun does not change the fact that it is still a specific name and must be capitalized.
