Irregular Plural Nouns in English

In the English language, most nouns follow a simple rule for forming plurals: add “-s” or “-es” to the end. However, a fascinating category known as irregular plural nouns deviates from these standard rules. These nouns often pose a challenge to learners due to their unique and unpredictable plural forms.

In this article, we’ll explore the concept of irregular plural nouns, how to identify them and provide illustrative examples.

What is an Irregular Plural Noun?

An irregular plural noun is a noun that does not follow the standard rules of pluralization, such as simply adding “-s” or “-es”. Instead, these nouns change their form entirely or follow different rules that can be traced back to Old English or other linguistic influences.

Examples of Irregular Plural Nouns

1. Child becomes children.
   • Explanation: Unlike regular nouns, “child” does not become “childs”. The word changes to “children” to indicate more than one child.
2. Foot becomes feet.
   • Explanation: The singular “foot” transforms into “feet” in the plural form, showcasing an irregular change.
3. Mouse becomes mice.
   • Explanation: Instead of adding a suffix, “mouse” changes internally to form the plural “mice.”
