An irregular noun is a noun that does not follow the standard rules of pluralization.
Here's how it works:
* Regular nouns form their plurals by adding "-s" or "-es" to the singular form. For example:
* cat - cats
* book - books
* box - boxes
* Irregular nouns, however, have unique and often unpredictable plural forms. They don't follow the simple rules of adding "-s" or "-es." Examples include:
* child - children
* woman - women
* foot - feet
* mouse - mice
There are many reasons why certain nouns are irregular. These include:
* Historical origins: The English language has borrowed words from many other languages, and some of these words retained their original plural forms.
* Sound changes: Some irregular plural forms reflect old sound changes that occurred over time.
* Simple quirks: Some irregular nouns are just...irregular!
