Overview
Comparatives compare two things. Superlatives describe the extreme — the most or least of a group. These are among the most frequently used structures in everyday English.
- Comparative: My house is bigger than yours.
- Superlative: This is the biggest house on the street.
Forming Comparatives and Superlatives
The rules depend on the length of the adjective.
One-Syllable Adjectives: Add -er / -est
| Adjective | Comparative | Superlative |
|---|---|---|
| tall | taller | the tallest |
| old | older | the oldest |
| cheap | cheaper | the cheapest |
| fast | faster | the fastest |
| long | longer | the longest |
| young | younger | the youngest |
Spelling Rules for -er / -est
| Rule | Adjective | Comparative | Superlative |
|---|---|---|---|
| Ends in -e: add -r / -st | large, nice, late | larger, nicer, later | the largest, nicest, latest |
| Ends in consonant-vowel-consonant: double the last letter | big, hot, thin, sad | bigger, hotter, thinner, sadder | the biggest, hottest, thinnest, saddest |
| Ends in -y: change to -ier / -iest | happy, easy, busy | happier, easier, busier | the happiest, easiest, busiest |
| Two consonants at end: just add -er / -est | dark, fast, tall | darker, faster, taller | the darkest, fastest, tallest |
Two-Syllable Adjectives
Some two-syllable adjectives use -er/-est, others use more/most, and some allow both:
| Use -er/-est | Use more/most | Both OK |
|---|---|---|
| Ending in -y: happy, easy, funny, busy, early, pretty | Ending in -ful: careful, helpful, useful | clever, narrow, simple, quiet, gentle |
| Ending in -ow: narrow, shallow | Ending in -less: careless, useless | common, polite, handsome |
| Ending in -le: simple, gentle | Ending in -ing: boring, exciting | |
| Ending in -ed: tired, bored | ||
| Ending in -ous: famous, nervous |
Three or More Syllables: Always Use More / Most
| Adjective | Comparative | Superlative |
|---|---|---|
| beautiful | more beautiful | the most beautiful |
| expensive | more expensive | the most expensive |
| interesting | more interesting | the most interesting |
| comfortable | more comfortable | the most comfortable |
| intelligent | more intelligent | the most intelligent |
Irregular Comparatives and Superlatives
These must be memorised — they don't follow any pattern:
| Adjective | Comparative | Superlative |
|---|---|---|
| good | better | the best |
| bad | worse | the worst |
| far | further / farther | the furthest / farthest |
| old | older / elder | the oldest / eldest |
| much / many | more | the most |
| little | less | the least |
Elder/eldest are used only for family members: my elder brother, the eldest child. Further can mean "more" (further information) or "more distant." Farther refers only to physical distance.
Using Comparatives
Structure: comparative + than
- London is bigger than Manchester.
- This film is more interesting than the last one.
- She speaks English better than me.
Without "than" (when the comparison is understood)
- Which is cheaper? (comparing two things already mentioned)
- Can you speak more slowly? (compared to your current speed)
Modifying Comparatives
You can make comparatives stronger or weaker:
| Modifier | Meaning | Example |
|---|---|---|
| much / far / a lot | big difference | She is much taller than her sister. |
| a little / a bit / slightly | small difference | This is a bit cheaper than that one. |
| even | more than expected | Today is even colder than yesterday. |
| no | not at all | This is no better than the old one. |
Never use "more" with -er forms:
- Wrong:
more bigger- Correct: bigger or much bigger
Using Superlatives
Structure: the + superlative (+ in/of)
- Mount Everest is the highest mountain in the world.
- She is the most talented student in the class.
- This was the worst day of my life.
- He is the best player on the team.
Prepositions with superlatives
| Preposition | Used with | Example |
|---|---|---|
| in | places, groups | the tallest in the class / in the world |
| of | periods, sets | the best of the three / the hottest day of the year |
| on | teams | the fastest on the team |
Superlative + Present Perfect
A very common and natural pattern:
- This is the best film I**'ve ever seen**.
- She is the most interesting person I**'ve ever met**.
- It was the worst meal I**'d ever eaten**.
Comparing Equals: As...As
When two things are the same, use as + adjective + as:
- She is as tall as her brother.
- This restaurant is as expensive as that one.
- He works as hard as anyone I know.
Negative: not as...as
- My car is not as fast as yours. (= yours is faster)
- The film wasn't as good as the book.
Not as...as is softer than a comparative:
- She's not as tall as her sister. (neutral)
- She's shorter than her sister. (more direct)
Double Comparatives: Getting More and More
To describe something that is changing over time:
| Type | Structure | Example |
|---|---|---|
| Short adjective | adjective-er and adjective-er | The days are getting longer and longer. |
| Long adjective | more and more + adjective | English is becoming more and more popular. |
The...the... (parallel change)
When one change causes another:
- The more you practise, the better you get.
- The cheaper the hotel, the worse the service.
- The sooner, the better.
- The older I get, the less I worry.
Less and Least (Downward Comparisons)
To compare downward, use less (comparative) and the least (superlative):
- This book is less interesting than that one.
- That was the least expensive option.
- He is the least experienced member of the team.
Less is used with uncountable nouns and long adjectives. For short adjectives, "not as...as" is more natural:
- Less natural:
He is less tall than his brother.- More natural: He is not as tall as his brother.
Common Mistakes
Mistake 1: Double comparative
- Wrong:
She is more taller than me. - Correct: She is taller than me.
Mistake 2: Forgetting "the" with superlatives
- Wrong:
He is best player on the team. - Correct: He is the best player on the team.
Mistake 3: Using -er with long adjectives
- Wrong:
This is beautifuler. - Correct: This is more beautiful.
Mistake 4: Using "more" with irregular forms
- Wrong:
This is more good. - Correct: This is better.
Mistake 5: Comparing with "as" incorrectly
- Wrong:
She is as tall than me. - Correct: She is as tall as me.
Mistake 6: Wrong preposition with superlatives
- Wrong:
the biggest city of the world - Correct: the biggest city in the world
Mistake 7: Forgetting to double consonants
- Wrong:
biger, hoter - Correct: bigger, hotter

- Compare things around you: "My desk is bigger than my shelf. My chair is the most comfortable in the room."
- Practise "the...the...": "The more I read, the more I learn."
- Use superlatives with experiences: "What's the best film you've ever seen? The worst food you've ever tasted?"
- Describe photos: Compare the people, places, or objects in a picture.
- Write product reviews: "This phone is lighter than the old model but more expensive."
