What is a Plural Noun?

Plural Noun Definition: A Plural Noun is a word that refers to more than one person, place, thing, or idea. It's the opposite of a singular noun, which refers to just one.

Why are Plural Nouns Important? They are essential for subject-verb agreement and for expressing quantity in English. Mastering plural forms helps you write and speak accurately and clearly.

Function in Grammar

Plural nouns are used to name more than one person, place, thing, or idea. They are the opposite of singular nouns, which refer to just one. For example:

• Singular Noun: cat, book, child
• Plural Noun: cats, books, children

Plural Noun vs Singular Noun: Plural nouns refer to more than one thing (e.g., cats), while singular nouns refer to one thing (e.g., cat).
