As soon as you can start using adjectives to describe people and things, you can begin to compare them. When we compare two items, we use the comparative form of adjectives.
If an adjective is a one syllable word we make the comparative by adding -er. If the adjective ends in one vowel and one consonant, double the consonant before adding -er.
- cheap -> cheaper
- old -> older
- big -> bigger
- thin -> thinner
If the word ends in -y, change -y to -i and add -er
- funny -> funnier
- happy -> happier
If the adjective has 3 or more syllables, we make the comparative by using more before the word
- comfortable -> more comfortable
- interesting -> more interesting
The tricky words are 2 syllable words: some (especially ending in -y) add -er for the comparatives, others use more. Some adjectives use both forms.
- angry -> angrier
- silent -> more silent
- quiet -> quieter, more quiet
- friendly -> friendlier, more friendly
Finally there are some irregular comparatives:
- good -> better
- bad -> worse
- far -> farther / further
When we compare more than two things we use the superlative form. Instead of -er, we use -est, instead of more, we use most.
- angry -> angriest
- silent -> most silent
- quiet -> quietest, most quiet
- friendly -> friendliest, most friendly
The irregulars are similar
- good -> best
- bad -> worst
- far -> farthest / furthest
