This document discusses comparative and superlative adjectives in English. It outlines three main rules for forming comparatives: (1) adding -er to one-syllable adjectives, (2) adding -ier to adjectives ending in y, and (3) using "more" plus the base adjective form for words of three or more syllables. It also notes some irregular comparatives like good/better and bad/worse. For superlatives, it explains using -est for one-syllable adjectives, -iest for words ending in y, and "most" plus the base form for multi-syllable adjectives, as well as the irregular forms like best/worst
