Understanding how to use comparative and superlative adjectives is crucial for expressing comparisons effectively in English. These grammatical forms allow you to describe the differences between two things or to highlight something at the extreme end of a scale. This guide will break down the rules of comparative and superlative adjectives, providing clear explanations and examples to help you master this essential aspect of English grammar.
Comparative Adjectives: Comparing Two Things
Comparative adjectives are used to show the difference between two nouns. Whether you’re talking about size, speed, or any other quality, comparatives help you indicate which of the two nouns possesses that quality to a greater degree. The basic structure for using comparative adjectives is:
Noun (Subject) + Verb + Comparative Adjective + than + Noun (Object)
The word “than” is essential in these constructions as it introduces the second item being compared. However, if the context is clear, the second item of comparison can sometimes be omitted.

Examples of Comparative Adjectives in Sentences:
- My car is faster than my neighbor’s car.
- This book is more interesting than the last one I read.
- Apples are healthier than candies.
- The blue shirt is cheaper than the red one.
- She is happier today than she was yesterday.
- He performed worse on the test compared to his previous performance.
- I like coffee better than tea. (Here, “than tea” is understood but not explicitly stated)
Superlative Adjectives: The Highest Degree
Superlative adjectives are used to describe a noun that is at the highest or lowest degree of a certain quality when compared to a group of things. They indicate the extreme – the most or least of something within a set. The structure for superlative adjectives is:
Noun (Subject) + Verb + the + Superlative Adjective + Noun (Object)
The word “the” is always used before a superlative adjective, and the group being compared can be mentioned or understood from the context.

- That was the worst movie I’ve seen this year.
- She is the best singer in the competition. (Here, “in the competition” is the understood group)
Forming Regular Comparative and Superlative Adjectives
The way you form comparative and superlative adjectives depends on the number of syllables in the base adjective. Here’s a breakdown of the rules:
One-Syllable Adjectives
For most one-syllable adjectives, you simply add -er to form the comparative and -est to form the superlative. If the adjective ends in a consonant-vowel-consonant pattern, double the final consonant before adding the suffix.
| Adjective | Comparative | Superlative |
|---|---|---|
| Tall | Taller | Tallest |
| Short | Shorter | Shortest |
| Fast | Faster | Fastest |
| Slow | Slower | Slowest |
| Big | Bigger | Biggest |
| Hot | Hotter | Hottest |
| Cold | Colder | Coldest |
| Sad | Sadder | Saddest |
| Glad | Gladder | Gladdest |
Two-Syllable Adjectives
For two-syllable adjectives, the rules are a bit more varied.
- Option 1: -er and -est: Many two-syllable adjectives can take -er and -est, especially those ending in -y, -ly, -ow, -er, and -le. For adjectives ending in -y, change the y to i before adding the suffix.
- Option 2: more and most: Alternatively, you can use more to form the comparative and most for the superlative.
In many cases, both forms are acceptable, but using more and most is generally considered safer if you are unsure.
| Adjective | Comparative (Option 1) | Superlative (Option 1) | Comparative (Option 2) | Superlative (Option 2) |
|---|---|---|---|---|
| Happy | Happier | Happiest | More happy | Most happy |
| Easy | Easier | Easiest | More easy | Most easy |
| Simple | Simpler | Simplest | More simple | Most simple |
| Gentle | Gentler | Gentlest | More gentle | Most gentle |
| Clever | Cleverer | Cleverest | More clever | Most clever |
| Quiet | Quieter | Quietest | More quiet | Most quiet |
Three or More Syllable Adjectives
For adjectives with three or more syllables, always use more to form the comparative and most to form the superlative.
| Adjective | Comparative | Superlative |
|---|---|---|
| Important | More important | Most important |
| Beautiful | More beautiful | Most beautiful |
| Expensive | More expensive | Most expensive |
| Intelligent | More intelligent | Most intelligent |
| Difficult | More difficult | Most difficult |
| Interesting | More interesting | Most interesting |
Irregular Comparative and Superlative Adjectives
Some common adjectives have irregular comparative and superlative forms that you need to memorize. These are exceptions to the regular rules.
| Adjective | Comparative | Superlative |
|---|---|---|
| Good | Better | Best |
| Bad | Worse | Worst |
| Far | Farther / Further | Farthest / Furthest |
| Little | Less | Least |
| Much / Many | More | Most |
Examples of Irregular Comparatives and Superlatives:
- This is the best coffee I’ve ever had.
- His performance was worse than expected.
- I walked further today than yesterday.
- She has less time than I do.
- He has more money than his brother.
Mastering comparative and superlative adjectives will significantly enhance your ability to express comparisons in English, making your communication clearer and more precise. Practice using these forms in your writing and speaking to solidify your understanding.
