Good, gooder, goodest

What? No way!

Are you competing with your friends to be number one at school, campus, or the office? You are number 1, and your friend could be number 2 in finishing the school project. You want to promote yourself, so your boss can give you a bonus? How do you say it when you want to compare yourself with others or compare one thing with another? Let’s use the structure of comparison.

One way of describing a person or thing is by saying that they have more of a particular quality than someone or something else. To do this, we use comparative adjectives, which are formed either by adding    -er at the end of the adjective, or placing more before it, e.g.

She’s more intelligent than her sister.

This is a bigger piece of cake.

It is also possible to describe someone or something by saying that they have more of a particular quality than any other of their kind. We do this by using superlative adjectives, which are formed by adding -est at the end of the adjective and placing the before it, or placing the most before the adjective, e.g.

He’s the most intelligent man I’ve ever met.

This is the biggest piece of cake.

Some rules about forming comparatives and superlatives

1. One syllable adjectives generally form the comparative by adding -er and the superlative by adding -est, e.g.

AdjectiveComparativeSuperlative
softsofterthe softest
cheapcheaperthe cheapest
sweetsweeterthe sweetest
thinthinnerthe thinnest
  • Note that if a one-syllable adjective ends in a single vowel letter followed by a single consonant letter, the consonant letter is doubled, e.g. thin – thinner/thinnestbig – bigger/biggest.
  • If an adjective ends in -e, this is removed when adding -er/-est, e.g. wide – wider/widest.
  • If an adjective ends in a consonant followed by -y-yis replaced by -iwhen adding -er/-est, e.g. dry – drier/driest.

2. More and most are sometimes used with one-syllable adjectives as an alternative to the -er/-est form when we particularly want to emphasize the comparison, or if the adjective occurs with another adjective which has more than one syllable, e.g.

The icing was supposed to be pink and white, but it looked more red than pink.

That sofa might look nice, but this one is more soft and comfortable.

3. Two-syllable adjectives which end in -y usually form the comparative by adding -er and the superlative by adding -est, (note the change of -y to-i in the comparative/superlative).

AdjectiveComparativeSuperlative
luckyluckierthe luckiest
prettyprettierthe prettiest
tidytidierthe tidiest

4. Two-syllable adjectives ending in -ed-ing-ful, or -less always form the comparative with more and the superlative with most. 

AdjectiveComparativeSuperlative
worriedmore worriedthe most worried
boringmore boringthe most boring
carefulmore carefulthe most careful
uselessmore uselessthe most useless

As a general rule, most other two-syllable adjectives also form comparatives and superlatives with more and most, apart from those ending in -y (see point 3 above). However, a few two-syllable adjectives can take either -er/-est or more/most. Here are three examples. 

AdjectiveComparativeSuperlative
narrownarrower/more narrowthe narrowest/most narrow
simplesimpler/more simplethe simplest/most simple
quietquieter/more quietthe quietest/most quiet


5. Adjectives which have three or more syllables always form the comparative and superlative with more and most.

AdjectiveComparativeSuperlative
dangerousmore dangerousthe most dangerous
difficultmore difficultthe most difficult
excitingmore excitingthe most exciting
ridiculousmore ridiculousthe most ridiculous

The only exceptions are some three-syllable adjectives which have been formed by adding the prefix un- to another adjective, especially those formed from an adjective ending in-y. These adjectives can form comparatives and superlatives by using more/most or adding -er/-est. 

AdjectiveComparativeSuperlative
unhappyunhappierthe unhappiest/most unhappy
unfriendlyunfriendlierthe unfriendliest/most unfriendly


6. The following adjectives have irregular comparative and superlative forms:

AdjectiveComparativeSuperlative
goodbetterthe best
badworsethe worst
farfarther/furtherthe farthest/furthest

The adjectives ill and well, describing bad and good health, have irregular comparative forms. The comparative of ill is worse, and the comparative of well is better, e.g. She’s feeling much better/worse today.

The usual comparative and superlative forms of the adjective old are older and oldest. However, the alternative forms elder and eldest are sometimes used. Elder and eldest are generally restricted to talking about the age of people, especially people within the same family, and are not used to talk about the age of things, e.g.

It’s the oldest/*eldest castle in Britain.

Elder cannot occur in the predicative position after link verbs such as bebecomeget, e.g.

We’re all getting older/*elder.

My brother is older/*elder than me.


7. Comparatives and superlatives of compound adjectives are generally formed by using more andmost, e.g.

Going skiing was the most nerve-wracking experience I’ve had.

Some compound adjectives have a first element consisting of an adjective which would normally form a comparative or superlative in one word, either by adding -er/-est, or by an irregular form. Such compound adjectives can, therefore form a comparative/superlative by using these changes to the first adjective, rather than by using more/most.

AdjectiveComparativeSuperlative
good-lookingbetter-lookingthe best-looking
long-lastinglonger-lastingthe longest-lasting
low-paidlower-paidthe lowest-paid

8. Some adjectives which already have a comparative or superlative meaning do not usually occur with -er/-est or more/most, unless we want to give special emphasis, often for humorous effect, e.g.

Mussels are my most favorite food.

Common examples of adjectives like these are: completeequalfavorite, and perfect.

Use of superlatives

Like comparatives, superlatives can be placed before nouns in the attributive position, or occur after be and other link verbs, e.g.

It is the most delicious chocolate cake I’ve ever eaten.

Annabel was the youngest.

This restaurant is the best.

As shown in the second two examples, superlatives are often used on their own if it is clear what or who is being compared. If you want to be specific about what you are comparing, you can do this with a noun, or a phrase beginning with in or of, e.g.

Annabel was the youngest child.

Annabel was the youngest of the children.

This restaurant is the best in town.

Another way of being specific is by placing a relative clause after the superlative, e.g.

This offer is the best I’m going to get.

Note that if the superlative occurs before the noun, in the attributive position, the in or ofphrase or relative clause comes after the noun, eg.

The best restaurant in town.

The best offer I’m going to get.

Although the usually occurs before a superlative, it is sometimes left out in informal speech or writing, e.g.

This one seems to be cheapest.

However, the cannot be left out when the superlative is followed by an of/inphrase, or a relative clause indicating the group of people or things being compared, e.g.

This one is the cheapest.

This one is cheapest.

This one is the cheapest of the new designs.

* This one is cheapest of the new designs.

This one is the cheapest I could find.

*This one is cheapest I could find.

Sometimes possessive pronouns are used instead of the before a superlative, e.g.

my youngest brother

her most valuable piece of jewellery

Ordinal numbers are often used with superlatives to indicate that something has more of a particular quality than most others of its kind, e.g.

It’s the third largest city in the country.

The cathedral is the second most popular tourist attraction.

In informal conversation, superlatives are often used instead of comparatives when comparing two things. For example, when comparing a train journey and car journey to Edinburgh, someone might say: the train is quickest, rather than: the train is quicker. Superlatives are not generally used in this way in formal speech and writing.

The opposite of comparative and superlative forms

Comparative and superlative forms with -er/-est and more/most are always used to talk about a quality which is greater in amount relative to others. If we want to talk about a quality which is smaller in amount relative to others, we use the forms less (the opposite of comparative more), and the least (the opposite of superlative the most). Less is used to indicate that something or someone does not have as much of a particular quality as someone or something else, e.g.

This sofa is less comfortable.

I’ve always been less patient than my sister.

The least is used to indicate that something or someone has less of a quality than any other person or thing of its kind, e.g.

It’s the least expensive way to travel.

She was the least intelligent of the three sisters.
