What is the difference between a singular noun and a plural noun?

A singular noun is a noun that refers to one person, thing, or place. A plural noun is a noun that refers to two or more people, things, or places.

For example, the singular noun "boy" refers to one person, while the plural noun "boys" refers to two or more people. The singular noun "book" refers to one book, while the plural noun "books" refers to two or more books.

Singular nouns are often used in sentences that talk about one person, thing, or place. Plural nouns are often used in sentences that talk about two or more people, things, or places.
