What does common noun mean?

A common noun is a word that refers to a general class of people, places, things, or ideas. It's a general name for something, not a specific name.

Here's a breakdown:

* General: It doesn't name a specific person, place, or thing.

* Class: It refers to a group or category.

* Uncapitalized: Common nouns are usually written with a lowercase letter unless they're at the beginning of a sentence.

Examples:

* People: *teacher*, *student*, *child*, *doctor*

* Places: *city*, *country*, *park*, *school*

* Things: *car*, *book*, *chair*, *table*

* Ideas: *love*, *happiness*, *freedom*, *justice*

In contrast, a proper noun is a specific name for a person, place, or thing and is always capitalized.

For example:

* Person: *John*, *Mary*, *Abraham Lincoln*

* Place: *New York City*, *France*, *Central Park*

* Thing: *The Titanic*, *The Great Wall of China*, *iPhone*

Remember, common nouns are the everyday words we use to talk about the general things around us.
