English comparatives and superlatives: grammar guide

Comparatives and superlatives are how English measures one thing against another: cheaper, more expensive, the best, as good as. This guide covers the basic forms first, then the patterns that show how big a difference is and how two changes move together.

Form building the words correctlyUse choosing the right patternForm and use both at once

Three ways to compare

Every comparison starts with one question: are the things equal, is one more than the other, or is one the most in its group?

Three ways to compare: as tall as, taller than, the tallest

Meaning Pattern Example
Equal as + adjective + as Ana is as tall as her father.
Less not as … as, less … than The ferry is not as fast as the plane.
More (two things) comparative + than Gold is heavier than silver.
Most (one from a group) the + superlative Jupiter is the largest planet in the solar system.

Basic patterns (B1)

Parts 1 to 3 cover the forms and the three basic ways to compare. If you are at B1, start here.

Advanced patterns (B2 to C1)

Parts 4 and 5 cover the size of a difference (much, slightly, by far, twice as … as) and patterns such as the more …, the more …. If you are at C1, use them as a review.

1

Form

Building the forms

Does the word take -er or more? Is it irregular?

The rule: Short words add -er and -est, long words take more and most, and good, bad, far, and little are irregular. Use one marker only: not more better.

Which ending?

Word Rule Comparative Superlative
small, cheap, young one syllable: add -er, -est smaller the smallest
nice, wide ends in -e: add -r, -st nicer the nicest
thin, sad one short vowel + one consonant: double it thinner the saddest
happy, busy, early ends in -y: change y to i happier the busiest
modern, famous most other two-syllable words: more, most more modern the most famous
beautiful, important three or more syllables: more, most more important the most beautiful
quickly, clearly -ly adverbs: more, most more quickly the most clearly
fast, hard, late adverbs without -ly: add -er, -est faster the hardest

Irregular forms

Word Comparative Superlative
good, well better the best
bad, badly worse the worst
far farther, further the farthest, the furthest
little (amount) less the least
much, many more the most

Farther or further?

Both are used for distance. Only further means extra or additional: further details, further questions.

Two-syllable words

Some two-syllable words, such as quiet, simple, narrow, and clever, accept both forms: quieter or more quiet. Words ending in -y usually take -ier.

Adjectives that come from -ed forms take more, even when they are short: more tired, more bored, more worried.

Common errors in this part

  • Double comparativeThis route is more shorter.✓ This route is shorter.Shorter already means more short.
  • -er or -est where more or most is neededThis sofa is comfortabler.✓ This sofa is more comfortable.Comfortable has more than two syllables.
  • Regular ending on an irregular wordHer score was badder than mine.✓ Her score was worse than mine.Bad is irregular: worse, the worst.
2

Use

Comparative or superlative?

Are you comparing two things or picking one from a group?

The rule: Use a comparative + than for two things and the + superlative for one from a group. After a superlative, use in for places and groups and of for sets and periods. One of the takes a plural noun.

Two things or a group?

Situation Clue words Example
Two people or things than This bag is lighter than that one.
One from a group of three or more in, of, all, ever, among She is the fastest runner in the club.
Second, third, and so on the second, the third K2 is the second highest mountain in the world.
The lowest degree the least This is the least expensive option.

Partner words after a superlative

Partner Use Example
in a place or an organization the oldest tree in the park, the best team in the league
of a period or a set the busiest week of the month, the cheapest of the three
one of the + plural noun one member of a top group one of the most famous paintings in the world
present perfect + ever your whole experience the longest I have ever waited

Two items, careful style

When there are exactly two, careful writers use the comparative: the taller of the two brothers. In everyday speech, the superlative is also common here. In informal American English, the simple past also appears after a superlative: the best movie I ever saw.

Common errors in this part

  • Comparative and superlative mixedAmir is the taller person in our office.✓ Amir is the tallest person in our office.In our office shows a group of more than two.
  • Wrong word after a superlativeIt is the longest bridge of the country.✓ It is the longest bridge in the country.A country is a place, so use in.
  • Singular noun after one of theThis is one of the hardest job I've had.✓ This is one of the hardest jobs I've had.One of the takes a plural noun.
3

Use

As … as, same, and different

Are the things equal, or is one less?

The rule: Use as + adjective + as for equal things and not as … as or less … than for less. Say the same as, similar to, and different from.

Equal and less

Pattern Meaning Example
as + adjective + as equal This room is as bright as the kitchen.
not as + adjective + as less The remake is not as funny as the original.
less + adjective + than less The new model is less noisy than the old one.
as much / many + noun + as equal amount I don’t have as many followers as you.
just as, almost as, nowhere near as how close The copy is almost as sharp as the original.

Fixed partners

Pattern Example
the same as My password is the same as before.
the same + noun + as He is the same height as his son.
similar to Portuguese is similar to Spanish in many ways.
different from The final version is different from the draft.
like (before a noun, for appearance or manner) She looks like her grandmother.

as tall as me or as tall as I am?

Both are accepted. A pronoun such as me is normal in everyday English. Adding the verb (as I am, as she does) sounds more formal. Different than (American) and different to (British) are also common.

Common errors in this part

  • as and than mixedHer car is as old than mine.✓ Her car is as old as mine.As … as uses as twice.
  • Wrong word after same, similar, or differentHis opinion is similar with mine.✓ His opinion is similar to mine.Similar takes to.
  • Wrong word after same, similar, or differentYour shoes are the same size like mine.✓ Your shoes are the same size as mine.The same + noun + as.
4

Form and use

How big is the difference?

Is the difference big or small? Is it a multiple?

The rule: Before a comparative, use much, far, or a lot for a big difference and slightly or a bit for a small one, not very. Multiples take twice, three times, or half + as … as.

slightly taller, much taller, twice as tall

Words before a comparative

Size of difference Words Example
Big much, far, a lot, considerably, significantly far more reliable, a lot cheaper
Small slightly, a bit, a little, marginally slightly longer, a bit more complicated
More than expected even, still The sequel was even better.
Strong superlative by far, easily by far the hardest question, easily the most popular

much more or many more?

Before Use Example
a noncount noun much more, a little more, a lot more much more space, a little more patience
a plural noun many more, a few more, a lot more many more options, a few more minutes

Multiples

Pattern Example
twice as + adjective + as The tablet is twice as thick as the phone.
three times as + adjective + as The tower is three times as tall as the church.
half as + adjective + as The new route is half as long.
twice the + noun + of The lake is twice the depth of the reservoir.
three times + comparative + than Common in news writing, but some editors avoid it, and twice bigger than is usually avoided in careful English.

Grammar recap

The Modifiers guide covers these words in a wider setting, together with very, extremely, absolutely, and so or such.

Common errors in this part

  • very before a comparativeThe new version is very better.✓ The new version is much better.Very does not go directly before a comparative.
  • Noncount and plural mixedWe need much more chairs.✓ We need many more chairs.Chairs is a plural noun.
  • Broken multiple patternThis box is twice as heavier as that one.✓ This box is twice as heavy as that one.Between as and as, the adjective keeps its basic form.

Form and use

Advanced patterns

Do two changes move together? Is something changing over time?

The rule: The + comparative …, the + comparative … links two changes. Repeat a comparative to show change over time. After than or as, a verb that matches the main verb can finish the comparison.

The more …, the more …

Pattern Example
the + comparative + subject + verb, the + comparative + subject + verb The earlier you book, the cheaper the ticket is.
the more + noun + subject + verb The more questions you ask, the more you understand.
the more / less + long adjective + subject + verb The less crowded the beach is, the happier I am.
no verb (short or formal) The bigger the screen, the higher the price. The sooner, the better.

The comparative comes first, then the subject and verb: the busier you are, not the more you are busy.

Change over time

Pattern Example
comparative + and + comparative The queue got longer and longer.
more and more + long adjective The puzzles became more and more difficult.
less and less + adjective The village is less and less crowded each winter.

Finishing the comparison with a verb

Main verb After than or as Example
action verb, present do / does She types faster than I do.
action verb, past did We stayed longer than they did.
be am / is / are / was / were The hall is bigger than it was.
modal can / will / could He can swim farther than I can.

than me or than I do?

Both are correct. Than me is normal in conversation. Than I do is more formal, and it is needed when the verb carries tense or meaning: She earns more now than she did then.

Common errors in this part

  • Missing theThe more you laugh, more you relax.✓ The more you laugh, the more you relax.Both halves need the.
  • Broken the more …, the more … patternThe more you are busy, the less you sleep.✓ The busier you are, the less you sleep.The comparative comes first, then the subject and verb.
  • Broken change-over-time patternThe music got more and more louder.✓ The music got louder and louder.Short words repeat the -er form.

Self-check

Is each sentence correct? Tap to see the answer. The part label tells you where to look if you were not sure.

Part 1Their new house is bigger than ours.

Correct. Big doubles the g before -er.

Part 1This exercise is more easy than the last one.

Incorrect. Easy ends in -y: This exercise is easier than the last one.

Part 2Lake Victoria is the largest lake in Africa.

Part 2It was one of the strangest day of my life.

Incorrect. One of the takes a plural noun: one of the strangest days of my life.

Part 3My score was not as high as I hoped.

Correct. Not as … as means less.

Part 3Her bag is different with mine.

Incorrect. Use different from: Her bag is different from mine.

Part 4The new train is a lot faster than the old one.

Correct. A lot shows a big difference before a comparative.

Part 4The second room is three times as larger as the first.

Incorrect. The adjective keeps its basic form: three times as large as the first.

Part 5The harder you train, the stronger you become.

Correct. Both halves use the + comparative.

Part 5My grandmother walks faster than I am.

Incorrect. Walks is an action verb, so use do: faster than I do.
