Comparative and superlative adjectives

Level: beginner

Comparative adjectives

We use comparative adjectives to show change or make comparisons:

This car is certainly better, but it's much more expensive.
I'm feeling happier now.
We need a bigger garden.

We use than when we want to compare one thing with another:

She is two years older than me.
New York is much bigger than Boston.
He is a better player than Ronaldo.
France is a bigger country than Britain.

When we want to describe how something or someone changes we can use two comparatives with and:

The balloon got bigger and bigger.
Everything is getting more and more expensive.
Grandfather is looking older and older

We often use the with comparative adjectives to show that one thing depends on another:

The faster you drive, the more dangerous it is. 
(= When you drive faster, it is more dangerous.)

The higher they climbed, the colder it got. 
(= When they climbed higher, it got colder.)

We use the with superlative adjectives:

Everest is the highest mountain in the world.

I have three sisters: Jan is the oldest and Angela is the youngest

How to form comparative and superlative adjectives

We usually add –er and –est to one-syllable words to make comparatives and superlatives:

old older oldest
long longer longest

If an adjective ends in –e, we add –r or –st:

nice nicer nicest
large larger largest

If an adjective ends in a vowel and a consonant, we double the consonant:

big bigger biggest
fat fatter fattest

If an adjective ends in a consonant and –y, we change –y to –i and add –er or –est:

happy happier happiest
silly sillier silliest

We use more and most to make comparatives and superlatives for most two syllable adjectives and for all adjectives with three or more syllables:

careful more careful  most careful
interesting more interesting  most interesting

However, with these common two-syllable adjectives, you can either add –er/–r and –est/–st or use more and most:


He is certainly handsomer than his brother.
His brother is handsome, but he is more handsome.
She is one of the politest people I have ever met.
She is the most polite person I have ever met.

The adjectives good, bad and far have irregular comparatives and superlatives:

good better best
bad worse worst
far farther/further  farthest/furthest

hello Sir,
Could you please tell me whether my sentences and the reasons are correct or not.
' she works harder than her late grandmother did.'
' The new car is more expensive than the old one was.'
I used 'did' because it refers to my grandmother that has passed away and 'was' because the old car is broken or isn't used anymore.

Thank you,Sir

Hello Risa warysha,

Both sentences are correct but we generally don't add the final verbs as they are understood from the sentence as a whole:

She works harder than her late grandmother.

The new car is more expensive than the old one.

hello, I have a problem with the adjective oversize:
I got into an argument with a friend weather more oversize is a correct usage of the adjective or not. To me it seems to be already in a comparative form, so I really wanna know if it can be used like shown previously

Hello goodusername

It would be a bit unusual to say 'more oversized', but in some contexts it could probably work, for example, if you are comparing two oversized items and one is bigger than the other.

All the best

May I ask these sentences are correct or not.

1) My friend is more careful than me.
2) My friend is careful than me.
3) My friend is carefully than I or me.
4) My friend is careful than I or me.

1 Until 4 is only using the comparative and in sentences 3 I know it was wrong but I still do not know why sentence 3 is wrong.

Thank You in advance for answering my question.

Hello Backlight,

The first sentence is correct. The others are incorrect.

We use 'than' after comparative forms. In (2) and (4) you have normal adjectives, not comparative forms. In sentence (3) you have an adverb, not a comparative form.

Dear teacher,
What is the correct way bellow When we use comparative adjectives.
1. He is taller than I.
2. He is taller than me.
3. He is taller than I am.
Thank you

Hello Janaka Liayanapathirana

All three of these are correct. I would recommend you use 2 in informal or neutral situations. 1 and 3 are appropriate for formal situations.

All the best

Hello everybody.... I´ve got a question, first of all I´ve been checking the use of adjectives (as comparatives, superlatives, adjective ends ED and ING), I understand what is the use of which of them, but I don´t know if those ones have any special rule to transform the "basic form" of the adjective into the others. For example:
Shock - Shocker (I´m not sure if this is the correct form) - Shockest - Shocked - Shocking
Horrible - More horrible - Most horrible - Horrified* - Horrifying*
Does anybody know something about it?

Thanks for all your support, the Learn English team makes a great job :)

Hello Alicia,
Some of the rules are easy to remember, such as the ones on the page about forming comparatives and superlatives.
Other rules are much less consistent, I'm afraid. The first thing you need to do is to identify the adjective. For example, 'horrible' is an adjective, but 'shock' is not - it is a verb or a noun.
You also need to recognise different words. For example, 'horrified' and 'horrible' have difference meanings:
horrible = very unpleasant (a characteristic)
horrified = shocked in a very unpleasant way (an feeling/emotion)
I think the best advice I can give is for you to make clear notes as you learn vocabulary. As you build up more and more examples you will start to see the patterns instinctively rather than through applying many complex rules. This is how native speakers learn such things, after all.
