Comparative adjectives in English

Hey everybody!

It’s that time again where we get the opportunity to improve our English that bit more with our weekly grammar post. Today we are going to look at comparative adjectives in English and how they are both formed and used.

Comparatives of one-syllable adjectives

In order to make the comparative form of a one-syllable adjective, we simply add “er” to the end of the adjective. In other words to make the comparative form of the adjective “tall”, we just add “er” to the end and we now have the comparative form “taller”. It’s also important to remember that after comparatives we use the conjunction “than”.


Jane is 1m 65 and Claire is 1m 60.

Jane is taller than Claire.

One-syllable adjectives and their comparative form:

Short – Shorter than

Big – Bigger than

Small – Smaller than

Old – Older than

Young – Younger than

Rich – Richer than

Nice – Nicer than

Poor – Poorer than

Pay close attention to the fact that we have doubled the “g” at the end of the adjective “big”. This is due to the fact that “big” is a one-syllable adjective which ends with a consonant which is preceded by a vowel.

Two or more syllable adjectives and their comparatives.

When adjectives have 2 syllables in English, the general rule for making the comparative form is to change the “y” to and “i” and add “er”.


Pretty – Prettier than

Funny – Funnier than

Silly – Sillier than

Dirty – Dirtier than

When we want to create the comparative form of adjectives that have two or more syllables and don’t end with the letter “y”, we cannot add “er” but instead use the adverb “more” before before the adjective.


Expensive – More expensive than

Comfortable – More comfortable than

Interesting – More interesting than

Dangerous – More dangerous than

Remember that if we wish to express the idea of not so much, then we need to use the adverb “less”.


My car is more comfortable than your car.

Your car is less comfortable than my car.

Football is more dangerous than tennis.

Tennis is less dangerous than football.

Adjectives which have irregular comparatives

As we all know, nothing is ever straight-forward. There is always an exception or irregularity along the way and comparative adjectives are no different. The 3 adjectives which have irregular comparatives are: good, bad and far.

Adjectives with their irregular comparatives:

Good – Better than

Bad – Worse than

Far – Farther / Further than


My English is better than my French.

The weather in England is worse than in Spain.

Your house is farther from Frankfurt than mine.

Bear in mind that “farther” and “further” mean the same when we are talking about distance but only “further” can be used if we are asking someone for additional information.
