​Comparative Adjectives

​A comparative adjective is used to compare one person, action, thing or state to another.

​

​It adds the suffix -er to the original adjective.

​

​e.g. bright - > brighter

​Superlative Adjectives

​A superlative adjective is used to compare one person, action, thing or state to all others in the same group.

​

​It adds the suffix -est to the original adjective.

​

​e.g. bright - > brightest

​Spelling Rules

​Most words can simply have the suffix –er and –est added to the end of them without having to make any changes to the root adjective.

​

However, there are some words that you need to watch out for!

​

Words that end in a ‘y’ These words need to have the ‘y’ changed into an ‘i’ before adding the suffix.

e.g. heavy → heavier tiny → tiniest

​

Double consonants Words that end in one vowel and then one consonant need to have the last consonant doubled.

​

e.g. flat → flatter

slim → slimmest

​

Words that end in an ‘e’ Words that end in an ‘e’ need to have the ‘e’ removed before the suffix is ended.

​

e.g. large → larger

fine → finest
