Irregular Adjectives | 100 Examples of Irregular Adjectives

Irregular adjectives are adjectives that do not follow the usual rules for forming comparative and superlative degrees. For example, good changes to better and best, while bad changes to worse and worst. Unlike regular adjectives that use -er, -est, more, or most, these adjectives have special forms that English learners need to remember.

In this article, you will learn 100 examples of irregular adjectives and their comparative and superlative forms, along with their meanings and uses in everyday English. Understanding these adjective forms will help you compare people, places, things, and situations correctly while improving your English grammar, vocabulary, speaking, and writing skills.

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.
