Forming the comparative and the superlative of adverbs

Adverbs ending in -ly use more to form the comparative and most to form the superlative.

Adverb Comparative Superlative
quietly more quietly most quietly
slowly more slowly most slowly
seriously more seriously most seriously
  • The teacher spoke more slowly to help us to understand.
  • Could you sing more quietly please?

Adverbs that don't end in -ly form the comparative and the superlative in the same way as adjectives: they take and ending of -er for the comparative and -est for the superlative. If an adverb ends in e you first have to remove the e then add the ending.

Adverb Comparative Superlative
hard harder hardest
fast faster fastest
late later latest
  • Jim works harder than his brother.
  • Everyone in the race ran fast, but John ran the fastest of all.

A few adverbs have irregular comparative and superlative forms.

Adverb Comparative Superlative
badly worse worst
far farther/further farthest/furthest
little less least
well better best
  • The little boy ran farther than his friends.
  • You're driving worse today than yesterday !
  • He played the best of any player.
