Common nouns and Proper nouns
What is the definition of the common noun?

Common nouns are everyday nouns that refer to the general category of people, places, things, or concepts.

According to Merriam-Webster, a common noun is “a noun that may occur with limiting modifiers (such as a or an, some, every, and my) and that designates any one of a class of beings or things”

The Cambridge English Dictionary defines a common noun as “a noun that is the name of a group of similar things, such as “table” or “book”, and not of a single person, place, or thing.”

What are the rules of the common noun?

The rules for common nouns include:

  1. Common nouns are not capitalized unless they begin a sentence. They always come in lowercase letters.
  2. Common nouns are not specific and do not refer to a particular person, place, thing, or concept.
  3. Common nouns can be pluralized by adding an -s or -es to the end of the noun. For example, “dog” becomes “dogs,” “cat” becomes “cats,” “book” becomes “books,” “student” becomes “students.”
  4. Common nouns can be modified with adjectives, such as “happy dog” or “big city”.
  5. Common nouns can be used in various grammatical contexts, such as subject, object, possessive, etc.

Examples,

  • As a subject, a common noun performing an action in a sentence, for example: “The dog barks.” (dog is the subject)
  • As an object, a common noun can be affected by the action in a sentence, for example: “He gave her a book.” (book is the object)
  • As a possessive, a common noun can indicate ownership or possession, for example: “The cat’s tail was fluffy.” (cat’s is a possessive form of the common noun cat)
  1. Common nouns can be combined with articles, such as “a” or “the” in phrases like “a dog” or “the city.”
  2. Common nouns are usually singular or plural depending on the context of the sentence, for example, “A dog is barking” or “Dogs are barking”

These are the general rules to be followed while using common nouns and there are also some exceptions to these rules in the English language.

For example:

  • Uncountable nouns: These are nouns that can’t be pluralized, such as “information” or “advice”.
  • Irregular nouns: Some nouns do not follow the rule of adding -s or -es to form their plural form, such as “man” becomes “men”, and “child” becomes “children”.
  • Compound nouns: Some nouns are formed by combining two words, and these nouns may have their own rules for pluralization, for example, “toothbrush” becomes “toothbrushes”
  • Proper nouns: Proper nouns are specific names and they are capitalized, but they still can be pluralized, for example, “John” becomes “Johns”. It becomes a common noun.
  • Foreign words: Some nouns are borrowed from other languages and they may have their own rules for pluralization, for example, “cactus” becomes “cacti”

Can a common noun become a proper noun?

There are common nouns that can become proper nouns. As you know, a common noun refers to a general category, while a proper noun refers to a specific one.

A common noun can become a proper noun when it is used to refer to a specific person, place, thing, or concept. For example, “city” is a common noun, but “New York City” is a proper noun because it refers to a specific city. “book” is a common noun, but “The Catcher in the Rye” is a proper noun because it refers to a specific book. “John” is a common noun, but “John Smith” is a proper noun because it refers to a specific person.

Important note: some words can be both common nouns and proper nouns depending on the context they are used in, for example, “University” is a common noun when it refers to a general concept of a university, but when it refers to a specific institution it becomes a proper noun, for example, “Harvard University”.
