The document discusses rules for forming the comparative and superlative forms of adjectives in English. For adjectives with one syllable ending in a consonant, the comparative is formed by adding -er and the superlative is formed by adding -est. For adjectives of two or more syllables, the comparative is formed by placing "more" in front and the superlative is formed by placing "most" in front. Some common irregular adjectives have unique comparative and superlative forms like "good", "bad", and "little".
