The document discusses the use of comparatives and superlatives in adjectives. Comparatives are used to compare two things and are formed using -er or by using conjunctions like "but". Superlatives are used to compare more than two things and use "the" since there is only one item with the superlative form. It provides examples of forming comparatives and superlatives based on the number of syllables and ending of adjectives, and notes irregular forms like good and bad.
