Irregular plural nouns are usually used to make a word mean more than one, you just add -s or -es. Like cat becomes cats. But some words don’t follow this rule. They have their way of showing there’s more than one. Irregular Plural Nouns Examples include, mouse becomes mice, not mouses. These words do not play by the usual rules, and each one has its special way to change. It might sound a bit tricky, but once you learn a few of them, it becomes fun to spot these special words and understand how they work.

What are Irregular Plural Nouns?
Irregular plural nouns are nouns that do not follow the typical pattern for forming plurals in English. In most cases, forming the plural of a noun involves adding “-s” or “-es” to the singular form. However, irregular plurals have unique ways of changing from singular to plural, and these changes often do not follow a consistent rule.
Examples:
- Man – Men
- Woman – Women
- Child – Children
- Tooth – Teeth
- Foot – Feet
- Mouse – Mice
- Goose – Geese
Rules for the Formation of Irregular Plural Nouns:

- Change of -us to -i
