Comparative adjectives are used to compare two things by expressing a difference in quality, size, degree, etc. They are formed by adding “-er” to shorter adjectives or by using “more” or “less” with longer ones. This lesson covers the rules, examples, and common mistakes to help you use them effectively.
What Are Comparative Adjectives?
Comparative adjectives compare two nouns by expressing differences in quality, size, degree, or other characteristics.
- Example: This book is longer than that one.
How to Form Comparative Adjectives

Using “More” or “Less” for Long Adjectives
