Difference Between Proper Noun and Common Noun

In simple words, nouns are the name of individuals, ideas, places, objects, etc. Nouns are the foundation of a language and a vital part of speech. When a child begins to speak, he starts from nouns and gradually forms sentences. Nouns are the essential grammatical element that a person should adequately understand. Proper nouns and common nouns are two types of nouns.

Proper Noun vs Common Noun

The main difference between a proper noun and a common noun is that a proper noun is the official name of things. They do not refer to a class, for instance, Mango. On the other hand, common nouns are also names, but they designate a particular style, not the actual name, for example, fruit. Hence, Mango is a proper noun while the fruit is a common noun.

Proper Noun vs Common Noun

A particular name of a person, organization, object, or place is known as a proper noun. Proper nouns are a significant part of speech in English grammar. It helps people to learn English to differentiate between subjects, objects, and verbs. Proper nouns are always capitalized when used in a sentence. Proper nouns are generally found in every language.

Common nouns are used to designate a class of objects or living organisms. In English grammar, a common noun is one of the primary nouns, and without a common noun, a person can not complete a sentence. Common nouns are typically associated with objects and people, but they have no connection to the official name of certain things.

What is Proper Noun?

A proper noun refers to the specific name of a person, place, or thing. In other words, it identifies only a single unit, for instance, Earth, Washington, America, China, Asia, Mercedes, Jennifer Lopez, Tuesday, etc. These are a few examples of proper nouns.

These nouns are always written with their first letter being capitalized, regardless of their position in a sentence. For example, “Will you be visiting New York this year?” Here in the above-given example, New York is a proper noun and is capitalized without any effect of its position in the sentence. Proper nouns can be identified by several terms based on the following categories: names of persons like Andrew, John, Victor, etc.

Titles of people such as Queen Victoria, President Obama, etc. Places like Russia, China, India, etc. Calendar months and days, for example, September, June, Tuesday, etc. Holidays include specific days like Christmas, Labour Day, Independence day, etc. Brand and company names like Puma, Sony, Samsung, Nokia, etc.

Titles of works include the title of particular works of art and literature like Mahabharata, The New York Times, Romeo and Juliet, etc. Hence, a proper noun is an essential part of a language that facilitates people to know the appropriate name of a particular thing. It makes the conversation more convenient.

What is Common Noun?

A generic name used to denote some object or person is a common noun. Everything existing in this world has a name, so people can converse about it and share thoughts about it. Without a common noun, no conversation can ever take place. For example, a person says, ‘look! There’s a dog.’

Here he indicates an animal by signifying its class and the other person gets the idea to look for a dog. In this sentence, ‘dog’ is an example of a common noun. Common nouns’ primary specification is that they aren’t capitalized except for some particular circumstances. They are only capitalized if they are a part of the title or the first word in a sentence. Common nouns can be divided into five types.

Countable nouns—as the name suggests, countable nouns refer to those nouns that can be counted, for example, cat, dog, miles, meters, chair, table, book, and many more.

Uncountable nouns— unlike countable nouns, these nouns refer to objects that can not be counted, for example, grass, milk, water, wind, sleep, ice, etc.

Collective nouns— these nouns are the name of groups, for example, herd, family, team, etc.

Concrete nouns— concrete nouns are associated with something that can be physically touched, for example, flower, cheese, body, etc.

Abstract nouns— abstract nouns are the opposite of concrete nouns and refer to something that can’t be touched, for example, culture, love, loyalty, honesty, etc.

Main Differences Between Proper Noun and Common Noun

  1. A proper noun is called proper because it is a direct and proper name for certain things. On the other hand, a common noun is called common because it is a name of a class having common traits.
  2. According to the grammatical rules, proper nouns should be studied first for better understanding, while common nouns should be reviewed later because they are more descriptive.
  3. The first latter of proper nouns is primarily capitalized in sentences regardless of their position. On the other hand, common nouns are capitalized only when they are the first word of the sentence.
  4. Proper nouns need only one explanation, and that’s the reason they aren’t classified. On the other hand, common nouns are divided into five categories.
  5. Tom, America, Lily, Peacock, t-shirt, etc., are examples of proper nouns. On the other hand, boy, nation, bird, cloth are examples of common nouns.


Nouns are very helpful to signify thought, person, spot, object, creature, and many other things. Without nouns, there is no conversation among people because it helps people identify things. Names are assigned to each object, and the word for a specific thing might be different in countries, but the meaning doesn’t change.

So, a person can say nouns to help to find out the meaning behind a sentence. The conversation is all about delivering thoughts and information. The word noun originated from the Latin word ‘nomen’ meaning name.

The presence of nouns can be seen in every sentence. They are used to address things a person desires to talk about. They are different from verbs.
