What are Comparative Adjectives?
Comparative adjectives are used to compare two nouns or pronouns. They show which of the two has a higher degree of a particular quality.
We use comparative adjectives when we want to say that one thing is "more" of a certain quality than another.
My car is faster than yours.
This book is more interesting than that one.
Forming Comparative Adjectives
The way we form comparative adjectives depends on the number of syllables in the adjective.
1. One-Syllable Adjectives
Add -er to the end of the adjective.
| Adjective | Comparative | Example |
|---|---|---|
| tall | taller | John is taller than Mike. |
| old | older | This building is older than the library. |
| fast | faster | A cheetah is faster than a lion. |
Spelling Rules for One-Syllable Adjectives:
- Ending in -e: Just add -r.
- large → larger
- nice → nicer
- Ending in consonant + single vowel + consonant (CVC): Double the last consonant before adding -er.
- big → bigger
- hot → hotter
- thin → thinner
2. Two-Syllable Adjectives Ending in -y
Change the -y to -i and add -er.
| Adjective | Comparative | Example |
|---|---|---|
| happy | happier | She looks happier today. |
| easy | easier | This exercise is easier than the last one. |
| busy | busier | I'm busier this week than last week. |
3. Two-Syllable Adjectives (not ending in -y) and Three or More Syllables Adjectives
Use more before the adjective.
| Adjective | Comparative | Example |
|---|---|---|
| modern | more modern | This design is more modern than the old one. |
| careful | more careful | You should be more careful. |
| expensive | more expensive | A car is more expensive than a bicycle. |
| beautiful | more beautiful | The sunset was more beautiful than I expected. |
Irregular Comparative Adjectives
Some common adjectives have irregular comparative forms that you need to memorize.
| Adjective | Comparative | Example |
|---|---|---|
| good | better | My English is better now. |
| bad | worse | The weather is worse today. |
| far | farther / further | His house is farther than mine. (distance) I need further information. (abstract) |
| little | less | I have less time than you. |
| much / many | more | She has more books than her brother. |
Using 'than' with Comparative Adjectives
We almost always use than after a comparative adjective when we explicitly state the two things being compared.
He is taller than his brother.
This movie is more exciting than the last one.
I feel better than yesterday.
If the comparison is clear from the context, we can omit 'than' and the second item.
I bought a new phone. It's faster. (Implied: faster than my old phone)
Making Comparisons Stronger or Weaker
We can use other words to emphasize or soften the comparison.
Stronger Comparisons
Use words like much, a lot, far, significantly, considerably before the comparative adjective.
She is much taller than her sister.
This car is a lot more expensive than that one.
The new system is far better than the old one.
Weaker Comparisons
Use words like a little, a bit, slightly before the comparative adjective.
I feel a little happier today.
This task is a bit more difficult than I thought.
He is slightly older than me.
Common Errors and How to Fix Them
| ✗ Incorrect | ✓ Correct | Why |
|---|---|---|
| He is more taller than me. | He is taller than me. | Do not use 'more' with -er endings. |
| This is difficulter. | This is more difficult. | 'Difficult' has three syllables, use 'more'. |
| She is gooder than him. | She is better than him. | 'Good' is an irregular adjective. |
| My car is faster that yours. | My car is faster than yours. | Always use 'than' for comparison. |
Real-World Examples
Comparing two items:
"Which phone is better?" "The new model is more powerful and has a bigger screen."
Describing changes:
The weather is colder today than yesterday. I need a warmer coat.
Making choices:
"This restaurant is more expensive, but the food is much better."
