How do I make the comparative and superlative adjectives?


What are comparative and superlative adjectives?

A comparative adjective does what it says: it compares two things or groups of things. We need to form a comparative adjective to show what is most or what tops a category.

NOTE: When a one-syllable adjective ends in a vowel and a consonant, then remember to double the consonant (see the example below). 

Making comparatives and superlatives

We form a comparative adjective for a one-syllable adjective by adding -er and -est to the adjective:

Big : bigger : biggest

Small : smaller : smallest

Noun (subject) + verb + comparative adjective + than + noun (object)
My dog is bigger (big + g + er) than your dog.

Easy list of some comparative and superlative adjectives

Form a comparative adjective for a two-syllable adjective by adding -ier and -iest to the adjective:

Pretty : prettier : prettiest

Happy: happiest : happiest

Fine: finer : finest

Finally, form the comparative adjective for two or more syllables by adding the word ‘more’ and ‘the most’.

Beautiful : more beautiful : the most beautiful

Delicate : more delicate : the most delicate

Be careful: good, bad, and far take special forms as they are irregular:

Good : better : the best

  • Those bottles of wine are good.
  • That vintage is better.
  • In my opinion, this one is the best.

Bad : worse : the worst

  • Her injuries are bad.
  • Their injuries are worse.
  • His injuries are the worst.

Far : further : the furthest

  • Kristof had to travel far to get here.
  • Anfal had to travel further than Kristof did.
  • Gian had to travel the furthest of all of us.
