> With adjectives that end in -e, add -r to form the comparative, and -st to form the superlative.
For example:
close - closer - closest
large - larger - largest
safe - safer - safest
wide - wider - widest
> Some adjectives have only one syllable, end with a consonant, and have a single vowel before the consonant. With these adjectives, double the last letter before adding -er to form the comparative, and -est to form the superlative. For example:
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 the y to i. Then add -erto form the comparative, and -est to form the superlative. For example:
busy - busier - busiest
dirty - dirtier - dirtiest
happy - happier - happiest
pretty - prettier - prettiest
More / Most
With some adjectives, you use more to make the comparative form, and most to make the superlative form.
Adjectives that form their comparative and superlative with more and most are usually adjectives with two or more syllables, or sounds. For example:
| ac-tive ex-pen-sive beau-ti-ful fa-mous | charm-ing for-tu-nate cheer-ful in-tel-li-gent | com-fort-a-ble pow-er-ful de-li-cious val-u-a-ble |
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.
