The document discusses the rules for forming comparatives and superlatives in English. There are three main ways to form comparatives: using "as...as", or adding "-er" to one-syllable adjectives and changing the ending to "-ier" for two-syllable adjectives ending in "-y" when using "than". For longer adjectives "more" is used. Superlatives are formed by adding "-est" or changing the ending to "-iest", or using "most/the most" depending on the adjective's length. Examples are provided to illustrate the rules for adjectives and adverbs. Quizzes are included for further practice with comparatives and superlatives.
