Comparative and Superlative AdjectivesDownload this explanation in PDF here.
To make the comparative form of adjectives (like 'bigger' or 'more expensive') and the superlative form (like 'biggest' or 'most expensive'), first we need to know how many syllables are in the adjective.
Adjectives with one syllable
Usually if an adjective has only one syllable, we add 'er' to make the comparative form. We add 'est' to make the superlative form.
- clean → cleaner / cleanest
- cold → colder / coldest
- small → smaller / smallest
- young → younger / youngest
- tall → taller / tallest
- wet → wetter / wettest
- big → bigger / biggest
- hot → hotter / hottest
- thin → thinner / thinnest
- dry → drier / driest
- nice → nicer / nicest
- large → larger / largest
There are a few adjectives that we have to use 'more' or 'most' with, even though they only have one syllable. We CAN'T add 'er' or 'est'.
- fun → more fun / most fun (NOT
funner / funnest)
- real → more real / most real (NOT
realer / realest)
- right → more right / most right (NOT
righter / rightest)
- wrong → more wrong / most wrong (NOT
wronger / wrongest)
For adjectives with two syllables we generally use 'more' or 'most'.
- careful → more careful / most careful
- bored → more bored / most bored
- clever → cleverer / cleverest
- simple → simpler / simplest
- narrow → narrower / narrowest
- quiet → quieter / quietest
- dirty → dirtier / dirtiest
- pretty → prettier / prettiest
- happy → happier / happiest
- ugly → uglier / ugliest
Adjectives with more than two syllables can only make their comparative by using 'more' and their superlative by using 'most'.
- beautiful → more beautiful / most beautiful
- intelligent → more intelligent / most intelligent
- interesting → more interesting / most interesting
- expensive → more expensive / most expensive
There are also some irregular adjectives. We just need to learn these forms.
- good → better → best
- bad → worse → worst
- far → further → furthest
- little → less → least
- much → more → most
