Definition

What is it?

An irregular plural noun is a noun that does not form its plural by adding -s or -es. Instead, its plural form changes in a unique way, sometimes by changing vowels or adding a different ending.

Simple Example

Quick Example

Imagine you have one 'man' working in your shop. If two more men join, you now have three 'men'. We don't say 'mans' because 'man' is an irregular plural noun.
