Comparatives and superlatives

Comparative sentences compare two things.

  • Moon Rock is smaller than Pittsville.
  • The train is more expensive than the bus.
  • I like the train, but the bus is cheaper.
  • Jill is better than Wendy at languages.
  • Jill is the better learner of the two. (Sometimes we use the in comparative sentences when it is understood which two people or things are being compared: the + comparative + noun)

Superlative sentences compare more than two things.

  • Sydney is the biggest city. (= of all the other cities)
  • The plane is the most expensive way to travel.
  • Of all the forms of transport, the plane is the most expensive.
  • Alison is the best swimmer.

This is how we make the comparative and superlative forms:

-short adjectives (one syllable):

adjective + -er, -est
small smaller smallest

-short adjectives that end in consonant + vowel + consonant (e.g., b + i + g):

adjective (double last letter) + -er, -est
big bigger biggest

-short adjectives that end in e:

adjective + -r, -st
nice nicer nicest

-two-syllable adjectives that end in y:

adjective (change y to i) + -er, -est
dirty dirtier dirtiest

-other two-syllable adjectives and longer adjectives:

more, most + adjective
beautiful more beautiful most beautiful

-irregular adjectives:

comparative and superlative forms are irregular
good better best
