Comparatives and superlatives: the basics

by | May 14, 2020

We form comparatives by adding -er to the end of an adjective or by putting the word more in front of it.

We form superlatives by adding -est to the end of an adjective and the in front of it or by putting the words the most in front of it.

These are the rules:

  • For one syllable adjectives, use -er or the …-est
  • For two syllable adjectives use more or the most.
  • For two syllable adjectives that end in -y, -er, -le or -ow you can use either form.
  • For adjectives with three or more syllables, use more or the most.

Here are some examples:

  • I was very cold, but I’m warmer now.
  • The blue coat is more expensive than the red coat.
  • Which flowers do you think are the nicest?
  • Dominic is the most popular boy in school.

Note that in sentences where you mention the thing you are comparing something with, you need to use the word than:

  • Susie is taller than me.
  • Peter is more sociable than his brother.

Be careful with the common adjectives good, bad and far. They are irregular, and their forms are:

  • good > better > best
  • bad > worse > worst
  • far > further > furthest
