Sometimes, an adjective can compare one noun with another. We add the letters -er onto an adjective when using it to compare. Look at this example:
Sally is short.
Jan is shorter.
The word short is an adjective. The word shorter is a comparative adjective. When we compare Jan to Sally, Jam is shorter.
Here are other adjectives that take -er when they are comparative:
high – higher
old – older
mild – milder
tall – taller
bright – brighter
Some adjectives double the last letter when adding -er to be comparative.
big – bigger
fat – fatter
red – redder
hot – hotter
thin – thinner
If an adjective already ends in an –e, just add –r to make it comparative.
loose – looser
late – later
large – larger
nice – nicer
simple – simpler
Some adjectives are used to compere nouns. Add -r and -er to an adjective to make it a comparative adjective.
