Comparative & Superlative

Comparatives and superlatives help you compare people, animals, places, and things. You already know how to add -er/-est and use more/most. Now it is time to learn the tricky irregular forms and some important rules about "less", "fewer", and when to use "more" and "most".

How to avoid common mistakes when mixing regular and irregular forms

When to Use

Comparing two things with irregular adjectives: "This hawker centre has better food than that one."
Comparing three or more things with irregular adjectives: "Out of all my subjects, Science is the best."
Using "fewer" with countable nouns: "There are fewer books on this shelf than on that one."
Using "less" with uncountable nouns: "There is less water in my bottle than in yours."
Using "more/most" with longer adjectives: "This painting is more beautiful than that one."

How to Form

Irregular Comparative and Superlative Forms

These adjectives do not follow the -er/-est pattern. You need to memorise them.

Adjective	Comparative	Superlative
good	better	best
bad	worse	worst
far	farther / further	farthest / furthest
little (amount)	less	least
many / much	more	most

"Less" vs "Fewer"

Word	Used With	Example
fewer	countable nouns	Fewer students came to school today.
less	uncountable nouns	There is less noise in the library.

"More / Most" with Longer Adjectives

Use "more" and "most" with adjectives that have three or more syllables, and with most two-syllable adjectives that do not end in -y.

Adjective	Comparative	Superlative
beautiful	more beautiful	most beautiful
expensive	more expensive	most expensive
comfortable	more comfortable	most comfortable
careful	more careful	most careful

Remember: Short adjectives (one syllable) use -er/-est. Two-syllable adjectives ending in -y change to -ier/-iest. Longer adjectives use more/most.

Key Rules

Never double-compare: Do not add -er or -est together with "more" or "most". Say "better", not "more better". Say "worst", not "most worst".
"Fewer" for countable, "less" for uncountable: If you can count the noun (apples, children, pencils), use "fewer". If you cannot count it (water, time, homework), use "less".
Irregular forms must be memorised: "Good", "bad", "far", "little", "many", and "much" do not follow regular rules. There is no shortcut -- you must learn them by heart.
Use "the" before superlatives: Always say "the best", "the worst", "the most beautiful". The superlative needs "the" in front of it.
"Than" follows comparatives: When comparing two things, use "than" after the comparative form. "My brother is taller than me." "This book is better than that one."
"Farther" vs "further": Both are correct. "Farther" is more common for physical distance ("The park is farther away"). "Further" is more common for additional amount ("I need further information").

Common Mistakes

Wrong	Right	Why
She is more better than me.	She is better than me.	"Better" is already comparative; do not add "more"
This is the most worst day.	This is the worst day.	"Worst" is already superlative; do not add "most"
He is the most goodest player.	He is the best player.	"Good" is irregular -- use "best", not "goodest" or "most good"
I have less pencils than you.	I have fewer pencils than you.	"Pencils" are countable, so use "fewer"
There are fewer water in the tank.	There is less water in the tank.	"Water" is uncountable, so use "less"
She sings most beautifully of all.	She sings the most beautifully of all.	Superlatives need "the" before them

Clue Words

Comparative clues (use the comparative form)

than, compared to, between the two

Superlative clues (use the superlative form)

the, of all, in the class, in the world, in the group, ever

"Fewer" clues (countable nouns)

books, students, apples, chairs, people, questions

"Less" clues (uncountable nouns)

water, time, money, homework, noise, traffic

Tip: If you see "than" in the sentence, you need a comparative form. If you see "the _ of all" or "the _ in the class", you need a superlative. For "fewer" vs "less", ask yourself: "Can I count it?" If yes, use "fewer". If no, use "less".

Practice Tips

Irregular forms drill: Write out the five key irregular sets (good/better/best, bad/worse/worst, far/farther/farthest, little/less/least, many-much/more/most) on a card and test yourself daily until they are automatic.
The counting test: When choosing between "fewer" and "less", try putting a number in front of the noun. Can you say "three waters"? No -- so use "less water". Can you say "three books"? Yes -- so use "fewer books".
The "more" check: After writing a comparative sentence, check whether you accidentally used "more" with an irregular form. Cross out the "more" if the word already changes form (better, worse, farther).
Read and spot: When reading a storybook or an article, circle every comparative and superlative you find. Check whether it is regular (-er/-est or more/most) or irregular. This will help you recognise the patterns naturally.
