Comparatives and Superlatives
We use Comparatives and Superlatives to compare two or more nouns.
The formation of the comparative and superlative depends on the number of syllables in the adjective:
One-syllable Adjectives
To form the comparative, we add -er to the end of the adjective.
To form the superlative, we add -est to the end of the adjective.
