Comparative and superlative adjectives

Comparative adjectives are used to compare differences between the two objects they modify (larger, smaller, faster, higher).

  • My house is larger than hers.
  • This box is smaller than the one I lost.
  • Jim and Jack are both fast, but Jack is faster. (“than Jim” is understood)

Superlative adjectives are used to describe an object which is at the upper or lower limit of a quality (the tallest, the smallest, the fastest, the highest). They are used in sentences where a subject is compared to a group of objects.

  • My house is the largest one in our neighborhood.
  • This is the smallest box I have.
  • Mount Everest is the highest mountain on Earth

Forming comparatives and superlatives depends on the number of syllables in the original adjective.

One syllable adjectives

Add -er for the comparative and -est for the superlative. If the adjective has a consonant + single vowel + consonant spelling, the final consonant must be doubled before adding the ending.

bigbiggerthe biggest
sadsadderthe saddest
Two syllables

Adjectives with two syllables can form the comparative either by adding -er or by preceeding the adjective with more. These adjectives form the superlative either by adding -est or by preceeding the adjective with most. In many cases, both forms are used, although one usage will be more common than the other. If you are not sure whether a two-syllable adjective can take a comparative or superlative ending, play it safe and use more and most instead.

Three or more syllables

Adjectives with three or more syllables form the comparative by putting more in front of the adjective, and the superlative by putting most in front.
