The document provides rules for comparing adjectives in English. It explains that to compare two things, add "-er" to the adjective, and to compare three or more things, add "-est". It then lists six specific rules for forming comparisons for different types of adjectives based on their spelling and syllable structure. The rules cover one-syllable adjectives, adjectives ending in consonant+y, adjectives ending in e, adjectives with two or more syllables, and adjectives used with "less" or "least". Students are instructed to practice the rules by answering questions and completing an exercise in their workbooks.
