What is a plural form?

Answer 1

A plural noun is one that refers to more than one of an object or concept. The plural is most often formed by adding S or ES to the singular form (also sometimes altering the spelling).

The plural forms of verbs are used with these nouns. In many cases, the plural noun will end in S and use a verb that does not end in S. Conversely, verbs used with single subjects will often end in S.

Example:

boy (one), boys (more than one boy)

The boy throws the football.

The boys throw the football.

There are a substantial number of "irregular" plural nouns not formed by adding S or ES.

Examples:

man-men

child-children

tooth-teeth

foot-feet

Answer 2

A plural form refers to a word or a form of a word that indicates more than one person, animal, object, or concept. It is used when referring to multiple entities instead of a singular entity.
