Read the rules and choose the correct grammatical forms of the adjectives

We add the ending -er/-est to one-syllable (e.g. large) or two-syllable adjectives having -y (e.g. happy).

• If a one-syllable adjective ends in -e, we add -r/-st: large— larger— the largest.

• If a one-syllable adjective ends in a consonant + one vowel + one consonant, we double the last consonant and add -er/-est: big— bigger — the biggest.

• If a two-syllable adjective ends in a consonant + -y, we change it into -i and add -er/-est: happy— happier — the happiest.

• easy — [easyer|easier|eassier] — the [easiest|eassiest|easyest];

• fat — [fater|fatier|fatter] — the [fattest|fatiest|fatest];

• safe — [saffer|safer|safier] — the [safiest|saffest|safest];

• early — [earlier|earlyer|earllier] — the [earlliest|earliest|earlyest];

• tall — [tallier|taller|taler] — the [tallest|talest|taliest].
