The following table gives the general Rules for Comparative Adjectives (there are some exceptions). Scroll down the page for more examples and explanations.

Rules for Comparative Adjectives

Rules for Comparative Adjectives

Rule 1: When an adjective consists of one syllable add er to the end to make it a comparative adjective.


clean cleaner
dark darker
thick thicker
soft softer
warm warmer
neat neater
broad broader
tall taller
old older

Exception to Rule 1: If the one syllable adjective ends with a consonant-vowel-consonant we need to double the last consonant before adding the er. However, if the last consonant is a w then we follow rule 1 instead.


big bigger
dim dimmer
fat fatter
fit fitter
flat flatter
few fewer
slow slower
low lower

Rule 2: When a two syllable adjective ends with y we need to replace the y with an i and then add the er.


busy busier
dirty dirtier
easy easier
funny funnier
noisy noisier
happy happier
heavy heavier
lovely lovelier

Rule 3: For an adjective with two or more syllabus (that does not end with y), we use add the word more or less in front of the adjective.


active more active, less active
careless more careless. less careless
famous more famous. Less famous
cheerful more cheerful, less cheerful
beautiful more beautiful, less beautiful
generous more generous, less generous
intelligent more intelligent, less intelligent
valuable more valuable, less valuable

Exceptions: There are some adjectives that have irregular comparative forms.


good better
bad worse
many more
much more
little less
far farther

How to form comparative and superlative adjectives?
This video shows the following:
For one syllable words we form the comparative and the superlative by adding “er” and “est” to the end of the word.

For two syllable words ending in “y” we change the “y” to “i” before adding “er” and “est”.

For other adjectives with two or more syllables we put “more” before the comparative and “most” before the superlative. We use the word “than” for the comparative and the definite article for the superlative.

There are a few exceptions to these rules. Good and well have the same comparative and superlative forms. The comparison for bad is worse and the superlative is worst. Much and many have the same comparative and superlative forms.
