Irregular Adjectives | 100 Examples of Irregular Adjectives

You probably already know words like big, small, and happy. But then English suddenly gives you strange forms like better instead of gooder or worse instead of badder. That confuses many learners.

The good news? Irregular adjectives are not hard once you see them used in real sentences. In this blog post, you will learn what irregular adjectives are, how they change, and how to use them naturally in daily English.

I have spent 8 years creating vocabulary flashcards and visual learning sheets for students. One thing I often notice is that learners remember irregular adjectives faster when they read short, real-life examples instead of long grammar rules.

What Are Irregular Adjectives?

Irregular adjectives are adjectives that do not follow the normal grammar rule when we compare things.

Most adjectives use:

• -er for comparison
• -est for the highest degree

Example:

• small → smaller → smallest

But irregular adjectives change in a different way.

Example:

• good → better → best

These special forms are called irregular adjectives.
