We can use comparative adjectives to compare two or more things with each other. Comparatives are made using regular adjectives, however how they are made depends on the type of adjective.  If you would like to learn more about comparatives, you’ve come to the right place. Feel free to look around, learn, and practice.

The rules for making comparatives are as follows:

1- One syllable adjectives

Comparative adjectives with only one syllable are made by adding “er” to the end of the adjective

Adjective + er + (than)

I like Tom’s car but Dave’s is faster.

My car is cleaner than my wife’s.London isn’t warmer than Barcelona.* NOTE: If the adjective ends with an e, we simply add an r.

Joanne is nicer than Sally.

2- One syllable adjectives ending with a vowel and consonant

We make comparatives with one syllable adjectives ending with a vowel and consonant by doubling the consonant at the end and adding “er” at the end of the adjective.

for example: big (“i” = vowel and “g” = consonant)

Adjective + doubled consonant + er + (than)

I don’t like her house, it’s too small, mine is bigger.

Egypt is hotter than France.

* NOTE: This is not always the case, there are some exceptions.

It’s cooler today than it was yesterday.

3- Two or more syllable adjectives

We make comparatives with adjectives having two or more syllables by adding more before the adjecitve

For example: complicated, /com-pli-ca-ted/, has four syllables.

more + Adjective (than)

He thinks the sequel is more interesting.

Learning Chinese is more difficult than learning English.

* NOTE: We can make negative comparisions using less with these types of adjectives.

Your couch is less comfortable than mine.

4- Two or more syllable adjectives ending with “y”

If an adjective having two or more syllables ends with “y”, we make comparatives by removing the “y” and adding with “ier” to the end of the adjective.

Adjective (minus “y”) + ier + (than)

I had a lot of friends in Poland but my friends in the UK are friendlier.

Spain is sunnier than Sweden.

5- Irregular adjectives

Some adjectives are irregular, meaning that they cannot be turned into comparative adjectives using the previously mentioned rules, they completely change. The following table shows a few examples:

Adjecitve Comparative
good/well better (than)
bad worse (than)
far farther/further (than)

I didn’t like their new album, I thought their first one was much better.

6- Describing similarities and making negative comparatives

We can say that two or more things are equal or not equal to each other using some of the following words and phrases

(not) as + Adjective + as

My life in the UK is just as busy as it was in Poland.

London is not as beautiful as Paris.

* NOTE: We can also incorporate a subject into this structure.

It is as warm in Spain as it is in Portugal.

It is also possible to use “(not) like” to say that two or more things are equal or not equal.
