Which house looks BIGGER and MORE BEAUTIFUL?: 5 basic rules to form comparatives and superlatives
When you compare two nouns, use the comparative form of the adjective. Many comparative adjectives end in –er.
We use the superlative form of an adjective to compare three or more kinds. Many words in the superlative form end in -est. We often add ‘the’ before the superlative form of the verb. But some words follow a different rule for their comparative and superlative forms.
We should follow these rules to avoid repeating our mistakes.
With adjectives that end in -e, add -r to form the comparative, and -st to form the superlative.
close closer closest
large larger largest
safe safer safest
wide wider widest
Some adjectives only have one syllable and end with a consonant with a single vowel before such consonant.
With these adjectives, double the last letter before adding –er to form the comparative, and -est to form the superlative.
big bigger biggest
dim dimmer dimmest
mad madder maddest
sad sadder saddest
Some adjectives have two syllables and end in -y. With these adjectives change y to i. Then add -er to form the comparative, and add -est to form the superlative.
busy busier busiest
dirty dirtier dirtiest
happy happier happiest
pretty prettier prettiest
With some adjectives, which have two or more syllables, use more to make the comparative form, and most to make the superlative form.
pow-er-ful more powerful most powerful
val-u-a-ble more valuable most valuable
bea-u-ti-ful more beautiful most beautiful
ac-tive more active most active
char-ming more charming most charming
cheer-ful more cheerful most cheerful
com-fort-able more comfortable most comfortable
del-i-cious more delicious most delicious
The comparative and superlative forms of some adjectives are completely different words. With these adjectives, you don’t add -er or more to form the comparative, or -est or most to form the superlative.
bad worse the worst
far further the farthest
good better best
