The document discusses the use of comparatives and superlatives. It provides examples of how to form comparatives and superlatives based on the number of syllables in adjectives. Comparatives are used to compare two things, using terms like "more" or "less." Superlatives use "most" or "least" to compare three or more items, and indicate the one that exhibits the quality to the greatest or least degree. Examples are given for one-syllable, two-syllable, and words ending in "-y."
