What is a common noun?

The most common part of speech that you will find in the English language is a common noun.

Simply put, a common noun refers to the name of any person, thing, place, or anything in a group or category. Furthermore, this is a known name, not specific to the person, thing, place, etc.

Common nouns can be abstract (like qualities and ideas) or concrete (tangible things).

Common nouns can be collective in nature as well.

This represents a collection or a group.

It’s important to note that every noun is usually an object or person, or place.

A common noun is not one of these, while a proper noun is specific to a particular thing, place, person, etc. Let’s break this down.

Examples in sentences

Here are some good examples to display common nouns:

  • All women love jewelry, and they love necklaces best.
  • Lisa had a Cheshire cat that loved drinking milk.
  • A dog is a faithful animal, but a cat or a hamster may be a different story.
  • Billy is a successful climber who has achieved much by climbing Mount Everest.
  • If the doorbell doesn’t work, be sure to use the door knocker.

Are common nouns lowercase or uppercase?

Unless a common noun begins a sentence, it is never uppercase. Assigning lowercase letters and capitals to words is a perennial issue and getting this right is critical to understanding the basics of the English language.

Frequently, spelling errors get created because they don’t use upper and lower cases appropriately.

Some common nouns, such as a president, may mislead you to think it requires a capital letter, for example.

This is because the word represents a person of authority. Unless the word is placed before the name of a particular president, the word does not start with a capital “p”.

Difference between common nouns and proper nouns

The distinguishing factors between proper and common nouns are generally easy to decipher.

When you use nouns in speech, it does not make any difference whether any noun is common or proper. This is because the syntax of speech isn’t influenced by them.

Every word that names something can be categorized as proper or common nouns. A common noun means a thing, a person, a place. A common noun is generic noun word form.

What is the most common way to form the plural of a noun and a common noun?

As you may have already guessed, the most common way to form any plural is simply by adding an “s” at the end of a noun. Look at the following examples:

  • “Boat” becomes “boats”
  • “House” becomes “houses”
  • “Dog” becomes “dogs”
  • “River” becomes “rivers”
  • “Girl” becomes “girls”

Although, there are some caveats. You cannot simply add an “s” to any common noun.

Highlighted below are some rules for making nouns pluralized:

  • When singular nouns end in the letters s, z, x, sh, or ch, the plural is made by adding “es” to the singular. Examples: bus (buses), church (churches), box (boxes), wish (wishes), etc.
  • When singular nouns end with consonants (any letters that are not vowels) and a “y”, the plural is formed by adding “ies” and dropping off the “y”. Examples: story (stories), spy (spies), daisy (daisies), etc.

Some irregular nouns may not follow any of the rules mentioned, like woman. Woman changes to “women,” and person becomes “people.”
