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.)

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

Hi Dear Sir,

I faced with some sentences in Azar blue regarding comparison of adjectives that I am not sure about even it is true or false. I am waiting to here from you even these are true of false:
the example is:
10. I don't like to work hard, but my sister does. I'm a lot lazier than my sister.
here first used alot then used lazier. is it right?

Hello M Ebrahim,

Yes, that sentence is fine. 'A lot' here is a modifier to make the comparative adjective 'lazier' stronger.

Thanks Sir,

I got the point.

Sorry, but your exercises are half hidden. :(

Hello Antonina M,

Thanks for telling us. We just made a major update to our site a few days ago, and this is one of the bugs that we are working on. We'll get it fixed as soon as we can – sorry for the inconvenience!

Is the following sentence correct ?

No other star is so bright as the Sun.


Hello Kelsie_29,

Yes, that is correct, though 'as bright as' is more common in modern English.

I have a question regarding an example which I saw in a book which is as follows -

The Shanghai Maglev has broken the record speed of all the other trains.

Is a comparison being made in the above statement?


Hi Kelsie,

There's an implicit comparison in that statement, for if this train has broken the speed record, then it is faster than all other trains (or 'the fastest train').

I find some difficulties with counting the syllables
how I could do it ? with pronounce or counting vowels I make some mistakes.
