Adjectives are words that describe or modify nouns. They add detail to sentences by answering questions like what kind, which one, or how many. When we want to compare two or more things, we use comparative and superlative adjectives.

Understanding how to use these forms correctly is essential for effective English communication. This article will walk you through the rules, exceptions, and usage of comparative and superlative adjectives—with examples and practical tips.

What Are Comparative Adjectives?

Comparative adjectives are used when comparing two nouns. They show how one thing differs from another in a particular quality (like size, age, or beauty).

Examples:

• This book is longer than the one I read last week.
• Maria is taller than John.
• That car is faster than mine.

• It’s the most expensive restaurant in town.
