What Are Comparatives?
Every day, we compare things around us. We say one city is bigger than another, one restaurant is more expensive than the one next door, or one friend is taller than another. These comparisons are at the heart of the English language, and the grammar structure that makes them possible is called the comparative form. Comparatives allow us to describe the difference between two people, two places, or two things by modifying adjectives to show that one has more (or less) of a particular quality than the other.
In English, comparatives are formed in two main ways: by adding -er to the end of short adjectives, or by placing the word more before longer adjectives. The word than typically follows the comparative adjective to introduce the second item in the comparison. Mastering these patterns is essential for describing the world accurately and expressing opinions with confidence.
Comparatives are used to compare two things. When comparing three or more things, we use superlatives instead. Think of comparatives as the grammar of choosing between two options.
When Do We Use Them?
Comparatives appear in a wide range of everyday situations. Whenever we look at two options and describe how they differ, we are using comparative forms. Here are the most common situations where comparatives are needed:
| Situation | Example |
|---|---|
| Comparing two people | Maria is taller than Sofia. |
| Comparing two qualities | Tokyo is more crowded than Oslo. |
| Making choices | This hotel is cheaper than the one near the beach. |
| Showing changes over time | The weather is getting colder and colder. |
| Describing progress | Her English is getting better every week. |
To show that something is changing or developing, use getting + comparative: "The days are getting longer." "Technology is getting more advanced." You can also repeat the comparative for emphasis: "It is getting colder and colder."
Short Adjectives — The -er Rule
For short adjectives — those with one syllable and some with two syllables — we form the comparative by adding -er to the end of the adjective. The word than connects the two things being compared.
Subject + be + Adjective + -er + than + Object
This pattern applies to most one-syllable adjectives and some common two-syllable adjectives ending in -y, -er, -le, and -ow.
| Adjective | Comparative | Example |
|---|---|---|
| tall | taller | Kenji is taller than his brother. |
| fast | faster | A cheetah is faster than a horse. |
| old | older | Rome is older than New York. |
| big | bigger | Istanbul is bigger than Lisbon. |
| hot | hotter | Dubai is hotter than London. |
| heavy | heavier | An elephant is heavier than a lion. |
| simple | simpler | This exercise is simpler than the last one. |
Long Adjectives — More + Adjective
For longer adjectives — those with two or more syllables (except the ones that take -er) — we form the comparative by placing more before the adjective. We do not add -er to long adjectives.
Subject + be + more + Adjective + than + Object
This pattern is used for adjectives with two or more syllables, such as beautiful, expensive, interesting, and comfortable.
| Adjective | Comparative | Example |
|---|---|---|
| beautiful | more beautiful | Prague is more beautiful than I expected. |
| expensive | more expensive | This restaurant is more expensive than the one on Park Street. |
| interesting | more interesting | The documentary was more interesting than the film. |
| comfortable | more comfortable | This chair is more comfortable than the wooden one. |
| dangerous | more dangerous | Driving in the city is more dangerous than driving in the countryside. |
| popular | more popular | Football is more popular than rugby in Brazil. |
Do not use more and -er together:
✘ She is more taller than her sister.
✔ She is taller than her sister.
✘ This book is expensiver than that one.
✔ This book is more expensive than that one.
Irregular Comparatives
Some of the most common adjectives in English do not follow the regular -er or more patterns. These adjectives have completely irregular comparative forms that must be memorised. They appear in everyday conversation constantly, so learning them by heart is essential.
| Adjective | Comparative | Example |
|---|---|---|
| good | better | Her pronunciation is better than mine. |
| bad | worse | The traffic in Cairo is worse than in Madrid. |
| far | farther / further | Seoul is farther from London than Paris is. |
| little | less | I have less free time than my younger brother. |
| much / many | more | There are more museums in London than in my city. |
Never add -er to irregular comparatives:
✘ This cake is gooder than the last one.
✔ This cake is better than the last one.
✘ My handwriting is badder than yours.
✔ My handwriting is worse than yours.
Farther is typically used for physical distance: "The airport is farther than I thought." Further can refer to physical distance as well, but it is also used for abstract or figurative meaning: "We need to discuss this further." In modern English, many speakers use them interchangeably for distance.
Spelling Rules for -er
Adding -er to an adjective is not always as simple as just attaching two letters. There are important spelling rules that govern how the ending is added, depending on the final letters of the adjective.
| Rule | Adjective | Comparative | Explanation |
|---|---|---|---|
| CVC → double the consonant | big | bigger | One vowel + one consonant at the end → double the last letter |
| hot | hotter | Same rule: h-o-t → hotter | |
| thin | thinner | Same rule: th-i-n → thinner | |
| Ends in -e → add -r only | nice | nicer | Already ends in -e, so just add -r |
| large | larger | Same rule: large + r = larger | |
| wide | wider | Same rule: wide + r = wider | |
| Ends in -y → change y to i, add -er | happy | happier | Drop -y, add -ier |
| easy | easier | Same rule: eas-y → easier | |
| early | earlier | Same rule: earl-y → earlier |
CVC stands for Consonant-Vowel-Consonant. When a one-syllable adjective ends in this pattern, double the final consonant before adding -er. For example: sad → sadder, wet → wetter, fat → fatter. However, do not double the consonant if the adjective ends in -w or -x: new → newer (not newwer).
Comparison is the foundation of understanding. When we say one thing is greater, smaller, or different, we give shape to the world around us.

Less and Not As…As
Comparatives are not only about saying something has more of a quality. We can also express that something has less of a quality by using less + adjective + than or the structure not as + adjective + as. Both forms express the same idea, but not as...as is far more common in everyday speech.
Subject + be + less + Adjective + than + Object
Subject + be + not as + Adjective + as + Object
Less + adjective + than is the direct opposite of more + adjective + than. The structure not as...as means the two things are not equal in that quality.
| Structure | Example | Meaning |
|---|---|---|
| less...than | This book is less interesting than the other one. | The other book is more interesting. |
| not as...as | This book is not as interesting as the other one. | Same meaning as above. |
| less...than | The film was less exciting than the trailer. | The trailer was more exciting. |
| not as...as | Amsterdam is not as big as Berlin. | Berlin is bigger than Amsterdam. |
| not as...as | My cooking is not as good as my mother's. | My mother cooks better than I do. |
To say two things are equal in a quality, use as + adjective + as (without "not"): "Ankara is as cold as Moscow in January." "He is as tall as his father." This is sometimes called the equative structure.
Double Comparatives
Double comparatives use the pattern the + comparative, the + comparative to show that two things change together. When one thing increases or decreases, the other thing changes at the same time. This is a powerful structure for expressing cause and effect.
The + comparative + (subject + verb), the + comparative + (subject + verb)
The first part describes the cause or condition, and the second part describes the result or consequence. Both parts must contain a comparative form.
| Cause / Condition | Result / Consequence |
|---|---|
| The more you study, | the better you get. |
| The harder you work, | the more successful you become. |
| The earlier you wake up, | the more time you have. |
| The older I get, | the wiser I feel. |
| The less you eat, | the hungrier you become. |
| The cheaper the product, | the lower the quality. |
Comparatives vs. Superlatives
Students often confuse comparatives and superlatives because they are closely related. The key difference is simple: comparatives compare two things, while superlatives compare three or more things and identify the one with the highest (or lowest) degree of a quality.
| Feature | Comparative | Superlative |
|---|---|---|
| How many things? | Two things | Three or more things |
| Short adjective ending | Adjective + -er | the + Adjective + -est |
| Long adjective form | more + Adjective | the most + Adjective |
| Connector word | than | in / of |
| good | better | the best |
| bad | worse | the worst |
| Example (short) | Tokyo is bigger than Seoul. | Tokyo is the biggest city in Japan. |
| Example (long) | Art is more creative than maths. | Art is the most creative subject. |
Ask yourself: "Am I comparing two things or three or more?" If the answer is two, use the comparative. If the answer is three or more, use the superlative. This simple question will prevent most errors.
Do not use the superlative when comparing only two things:
✘ Between the two brothers, Ali is the tallest.
✔ Between the two brothers, Ali is the taller.
✘ Of these two options, this is the best.
✔ Of these two options, this is the better.
