This document discusses the formation of comparative and superlative adjectives in English. It explains that comparatives are formed using "er" for one-syllable adjectives, "more" for two-syllable adjectives, and "most" for adjectives with more than two syllables. Superlatives are formed by adding "-est" to one-syllable adjectives and those ending in certain letters, and using "most" for other adjectives. Some adjectives like "good", "bad", "far" have irregular forms.
