A Plural Noun refers to more than one person, place, thing, or idea. It means there are two or more of something. Usually, we add -s or -es to make a noun plural, but some words change completely. For example:

Two cats, three books, many chairs.
"I have five pencils." (This means I have more than one pencil.)

Some special plural nouns don’t follow the regular rules. For example:

Child → Children
Mouse → Mice
Sheep → Sheep (stays the same in both singular and plural)

In simple words, singular means one, and plural means more than one!
