When you want to compare two people, places, or things in English, you need comparative adjectives. Whether you're saying that something is bigger, more expensive, or better, understanding how to form comparatives correctly is essential for clear communication.
What Are Comparative Adjectives?
Comparative adjectives are modified forms of adjectives used to compare two nouns. They show that one thing has more (or less) of a quality than another.
Base adjective: tall
Comparative: taller
John is taller than Mark.
The way you form the comparative depends on the adjective's length and spelling.
Rule 1: Short Adjectives (One Syllable)
For most one-syllable adjectives, add -er to form the comparative:
tall → taller
fast → faster
old → older
young → younger
small → smaller
cheap → cheaper
clean → cleaner
warm → warmer
Spelling Rules for Short Adjectives
Adjectives ending in -e: Add only -r
large → larger
nice → nicer
safe → safer
wide → wider
late → later
Adjectives ending in consonant + vowel + consonant: Double the final consonant
big → bigger
hot → hotter
thin → thinner
fat → fatter
wet → wetter
sad → sadder
Adjectives ending in -y: Change y to i and add -er
dry → drier
shy → shier
Rule 2: Two-Syllable Adjectives Ending in -y
For two-syllable adjectives ending in -y, change the -y to -i and add -er:
happy → happier
easy → easier
busy → busier
funny → funnier
pretty → prettier
angry → angrier
dirty → dirtier
early → earlier
heavy → heavier
lazy → lazier
Rule 3: Long Adjectives (Two or More Syllables)
For most adjectives with two or more syllables, use more before the adjective:
expensive → more expensive
beautiful → more beautiful
interesting → more interesting
comfortable → more comfortable
difficult → more difficult
important → more important
intelligent → more intelligent
careful → more careful
Two-Syllable Adjectives That Can Use Either Form
Some two-syllable adjectives can use either -er or more:
simple → simpler or more simple
quiet → quieter or more quiet
clever → cleverer or more clever
narrow → narrower or more narrow
gentle → gentler or more gentle
common → commoner or more common
Rule 4: Irregular Comparatives
Some common adjectives have completely irregular comparative forms that you must memorize:
good → better
bad → worse
far → farther / further
little → less
much / many → more
old → older / elder
Good vs Better
Bad vs Worse
Far: Farther vs Further
Farther — typically used for physical distance:
London is farther from Paris than Brussels.
Further — used for physical distance AND abstract meanings:
We need to discuss this further.
The hotel is further down the road.
Old: Older vs Elder
Older — general comparison of age:
My car is older than yours.
She is older than me.
Elder — used only for family members, and not with "than":
My elder brother lives in London.
She is my elder sister.
Using "Than" in Comparisons
When comparing two things directly, use than after the comparative:
Tokyo is bigger than Osaka.
Gold is more expensive than silver.
Running is harder than walking.
My new job is better than my old one.
Pronouns After "Than"
After "than," you can use either subject pronouns or object pronouns. Both are acceptable:
Comparisons Without "Than"
You don't always need "than." Sometimes the comparison is implied:
I need a bigger apartment. (bigger than my current one)
Can you speak more slowly? (more slowly than you are now)
This year has been better. (better than last year)
Modifying Comparatives
You can make comparatives stronger or weaker using modifiers:
Making Comparatives Stronger
much better — This is much better than before.
far more expensive — Cars are far more expensive now.
a lot easier — This test was a lot easier.
significantly higher — Prices are significantly higher.
considerably larger — The new office is considerably larger.
Making Comparatives Weaker
slightly better — This version is slightly better.
a little more difficult — The exam was a little more difficult.
a bit older — He's a bit older than me.
somewhat cheaper — This brand is somewhat cheaper.
Double Comparatives
Use double comparatives to show that two things change together:
The + comparative, the + comparative
The more you practice, the better you get.
The older I get, the wiser I become.
The harder you work, the more you earn.
The sooner, the better.
The bigger the house, the higher the price.
Repeated Comparatives
To show continuous change, repeat the comparative:
The city is getting bigger and bigger.
Housing is becoming more and more expensive.
She's getting better and better at tennis.
The days are growing shorter and shorter.
Technology is advancing faster and faster.
Less and Fewer
To show that something has a smaller amount of a quality, use less + adjective:
This book is less interesting than that one.
The second option is less expensive.
He seems less confident today.
Less vs Fewer
Less — for uncountable nouns:
I have less time than before.
There is less traffic on weekends.
Fewer — for countable nouns:
I have fewer books than my sister.
There are fewer cars on the road today.
Common Mistakes to Avoid
Mistake 1: Using "more" with -er adjectives
Never use "more" with adjectives that already have -er.
Mistake 2: Adding -er to long adjectives
Mistake 3: Forgetting to double consonants
Mistake 4: Using irregular forms incorrectly
Mistake 5: Using "very" instead of "much"
Mistake 6: Confusing comparative and superlative
Use comparative for two things, superlative for three or more.

Summary
Key Rules:
- Short adjectives (1 syllable): Add -er (tall → taller)
- Adjectives ending in -y: Change to -ier (happy → happier)
- Long adjectives (2+ syllables): Use more (more beautiful)
- Irregular: good → better, bad → worse, far → farther/further
- Use than to complete the comparison
- Use much/far/a lot to strengthen comparatives
- Use slightly/a bit to weaken comparatives
- Never use "more" + "-er" together
- Never use "very" with comparatives
Comparative adjectives are essential for everyday English. From shopping ("This one is cheaper") to describing people ("She's more experienced") to making decisions ("The first option is better"), you'll use them constantly. Master the spelling rules, memorize the irregular forms, and you'll be comparing things like a native speaker in no time!
