Definition

What is it?

An irregular plural is a word that changes its form in a special way when it goes from one (singular) to many (plural). Unlike most words that just add '-s' or '-es', irregular plurals follow their own unique rules.

Simple Example

Quick Example

Imagine you have one 'child' in your family. If you have more than one, you don't say 'childs', right? You say 'children'. So, 'child' becoming 'children' is an example of an irregular plural.

Worked Example

Step-by-Step

Let's find the irregular plural for 'mouse'.

1. Start with the singular word: 'mouse'. This means one mouse.
---
2. Think about how we usually make words plural. We often add '-s' or '-es'. If we added '-s', it would be 'mouses'.
---
3. Does 'mouses' sound correct for more than one mouse? No, it doesn't.
---
4. The English language has special rules for some words. For 'mouse', the plural form is 'mice'.
---
5. So, 'mouse' (singular) becomes 'mice' (plural). This is an irregular plural because it didn't just add '-s' or '-es'.

ANSWER: The irregular plural of 'mouse' is 'mice'.

Why It Matters

Understanding irregular plurals is crucial for clear communication, whether you're writing a news report or giving a presentation. Journalists and lawyers need to be precise with words, and authors use correct plurals to tell their stories effectively. Good grammar makes your message strong and easy to understand.

Common Mistakes

MISTAKE: Adding '-s' to all words to make them plural, e.g., 'mans' | CORRECTION: Some words have special plural forms, like 'man' becomes 'men'.

MISTAKE: Confusing words that look similar but have different irregular plurals, e.g., 'foot' to 'foots' | CORRECTION: 'Foot' becomes 'feet', just like 'tooth' becomes 'teeth'.

MISTAKE: Forgetting that some words don't change at all, e.g., 'sheeps' | CORRECTION: Words like 'sheep' and 'fish' have the same singular and plural form.
