Comparatives and Superlatives
Adjectives and adverbs have comparative and superlative forms. The comparative indicates that one thing has more of the quality than another thing. The superlative indicates that one object has the highest degree of a quality.
For most adjectives of one syllable and some adjectives of two syllables, add –er to make the comparative and –est to make the superlative.
Examples: sweet, sweeter, sweetest; high, higher, highest; cold, colder, coldestFor longer adjectives and adverbs, the comparative is formed by adding more before the word, and the superlative is added by adding most.
Examples: hilarious, more hilarious, most hilarious; quickly, more quickly, most quickly; delicious, more delicious, most deliciousThere are some special cases in English, as for instance good, better, best and bad, worse, worst.
