You have a pet mouse and you call it "mousey," but that's kind of boring, right? It’s because mousey is a common noun that’s generally used for all mice. 

Instead, you gave it a name: "Squeak." Cool name, right? Here Squeak is a particular name for your mouse that is a proper noun. 

The categorization of things makes them common nouns, while naming them specifically creates proper nouns. "A proper noun is a specific name for a particular person, place, thing, or idea." 

A study reported that participants showed a 15% faster response time when identifying proper nouns compared to common nouns. 

In this article, I'll walk you through proper nouns, their types, rules, and how they play a key role in clear communication.

What are proper nouns?

The proper nouns are a special name, person, place, or thing that is written with a capital letter. These nouns play an important role in our communication. Human brains have the instinct to categorize and name things around them. 

It is something like: 

“Anna visited the Grand Palace during her winter vacation."

In this sentence, "Anna" and "Grand Palace" are proper nouns

This type of noun is distinct from common nouns, which refer to general categories. Proper nouns pinpoint individual entities, making them a necessary type of noun in language. 

Understanding the different types of nouns, especially the difference between proper and common nouns, is important for clear communication and understanding language. 

Types of proper nouns

You have a friend named Nancy who is studying Physics at Harvard University. You just read four proper nouns in the previous sentence! All of them are different types, which I will explain below.

As proper nouns refer to the specific name of any entity, their types can be vast. But I am categorizing them into 10 major types here:

  1. Personal names: First names, middle names, last names, and even nicknames are proper nouns and should be written with the first letter capitalized.

Titles and respectful terms also fall in this category.

  • First name: Nancy 
  • Last name: Smith
  • Full name: Nancy Smith
  1. Geographical names:

Names given to areas marked by geographical boundaries are proper nouns.

  • Countries: Canada, Japan, and South Africa
  • Cities: New York, London, and Mumbai
  • Continents: Europe, Africa, and Antarctica
  • Bodies of water: Pacific Ocean, Mediterranean Sea, Lake Victoria
  • Parks and forests: Yellowstone National Park, Black Forest
  1. Historical periods and events:

We often refer to events and historical periods with a proper noun.

  • Eras: The Renaissance, The Industrial Revolution
  • Wars: World War II, and the American Civil War
  • Specific events: The French Revolution, The Boston Tea Party
  1. Brands and Products:

Names of things that specify a unique trait or category are proper nouns too.

  • Car models: Toyota Corolla, Ford Mustang
  • Technology products: iPhone, PlayStation
  • Food and drink brands: Starbucks, Heinz
  1. Titles of Works:

Titles given to creative works and arts always specify them and create a unique image in minds. That’s why they fall under proper nouns.

  • Books: "To Kill a Mockingbird," "The Great Gatsby"
  • Movies: "Star Wars," "The Godfather"
  • Songs and albums: "Bohemian Rhapsody," "Thriller"
  • Artworks: "Mona Lisa," "The Starry Night"
  1. Languages and Nationalities:

Although nationalities represent a large group of people, they are proper nouns as they specify a group from hundreds of groups.

  • Languages: Spanish, Arabic, and Russian
  • Nationalities: American, Japanese, Australian
  1. Days, Months, and Holidays:

When referring to periods using a specific term, make them proper nouns.

  • Days of the week: Monday, Friday
  • Months: January, August
  • Holidays: Easter, Diwali, and Ramadan

Articles with proper nouns

Is that name one you've heard of? “The Donald Trump” or “The David Ogilvy”? I don’t think anybody has because mostly an article is not used with a proper noun. It should be simply “Donald Trump” and “David Ogilvy.” 

However, we use articles when a preposition is there to provide additional information about a proper noun. When we say Dwayne “The Rock” Johnson, we are not using an article for the proper noun but for the preposition "Rock.” 

Similarly, the name of a country is always written without an article: “Pakistan” and "America," but when writing their official names in a sentence, we go: 

“The Islamic Republic of Pakistan” and “The United States of America.” The article “the” is introduced for the prepositions “Islamic Republic” and “The United States.”

Capitalization Rules of Proper Noun

You see a movie titled Damsel or the Spellbound. Both of them are mentioned in capital letters because they are proper nouns. The first letter of a proper noun is always capitalized, no matter where it is in a sentence. 

A 2019 NAEP survey found that about 27% of fourth-grade students in the U.S. struggle with using proper nouns correctly. 

But why is it so difficult? Understanding when to capitalize a noun can be challenging, especially for children or beginners. The trick is to identify if the word is pointing to a specific thing or not. 

For example:

  • He was not happy with the remarks of Albert.

“Albert” is the last word in the above sentence. But still, the first letter is in capital form.

If a proper noun is a combination of two or more words, then capitalize the first letter of each word. As I have done in the following sentence: 

  • I visited the Golden Gate Bridge during my trip to San Francisco, California.

Proper adjectives

To better explain what proper adjectives are, let me give you an example. 

Imagine you're in a park, sitting and enjoying your time. There you see a large tree, a colorful bench, or a playful squirrel. 

If you've been to a park like this before, you might say, "I went to Central Park." The word "Central" is a proper adjective because it describes a specific park.

Examples:

  • From a person: Shakespearean (relating to Shakespeare)
  • From a place: Italian (relating to Italy)
  • From a thing: Braille (relating to Louis Braille)

More examples in sentences:

  • I love reading Shakespearean sonnets.
  • She enjoys eating Italian food.
  • The Braille system is used by many visually impaired people.

The proper adjectives are always capitalized, just like proper nouns.

Proper nouns vs. common nouns with examples

Do you know the difference between common and proper nouns? If not, then don’t worry; the below examples and explanations will help you understand. 

Learning the difference between these nouns helps you capitalize words correctly, use articles properly, and effectively convey specific information.

Let's learn their differences and provide examples to explain each type.

Common noun

While visiting a zoo, you might see different animals, cages, and signs. The words animals, cages, and signs are the common nouns. These nouns are general and non-specific words. 

These words are not capitalized (unless at the beginning of a sentence). In common nouns, you add articles (a, an, the). These nouns are generally used to categorize things or entities. 

Examples: laptop, water bottle, pencil, and door. 

Use of examples in sentences: 

  • I put the laptop on the table
  • Can you pass me my water bottle?
  • She has a new pencil box
  • Can you please close the door?

Proper noun

Did you ever shop at a mall? If yes, then you have seen many things that probably you don’t know are proper nouns, just like the Hermes shop, Gucci bag, or Dior lip gloss. 

The italic words are the proper nouns that specify special things in the mall. Proper nouns have specific and unique identifiers. 

They are always capitalized in sentences. In proper nouns, they usually don't take articles (a, an, the) unless part of the name. These nouns refer to individual entities.

Examples: Mark Zuckerberg, Taj Mahal, or NASA. Use of examples in sentences:

  • Mark Zuckerberg founded Facebook.
  • The Taj Mahal is a beautiful mausoleum located in Agra, India.
  • NASA launched the Apollo 11 mission to the Moon.

Nouns that can be either proper or common

Now this can be a little challenging for you because some nouns can function as either proper or common nouns, depending on how they're used in a sentence.

A 2019 NAEP survey found that about 27% of fourth-grade students in the U.S. struggle with using proper nouns correctly. 

But why is it so difficult? Understanding when to capitalize a noun can be challenging, especially for children or beginners. The trick is to identify if the word is pointing to a specific thing or not. 

For example, while "mom" is typically lowercase when used as a general term, it's capitalized when used as a specific name.

Common noun: I love mom. Proper noun: Call Mom for help.

These are common nouns, but when they are used in such a way that they pinpoint a single entity or multiple entities falling under the same noun, they are proper nouns now.

Summing up

Proper nouns are an essential part of grammar that makes your writing or thought more specific. These nouns include everything like name, place, thing, movie, or brand. 

Proper nouns help us to show or indicate unique things in the world. The appropriate use of proper nouns not only improves grammar but also adds clarity to the expression. 

So, start implementing the practices that I have mentioned above. And let your writing and communication become more precise, engaging, and impactful.
