This document discusses how to form the comparative and superlative forms of adjectives in English. It provides rules for forming comparatives and superlatives depending on the number of syllables in the adjective. For one-syllable adjectives, the comparative takes -er and the superlative takes -est. For two-syllable adjectives ending in -y, the comparative takes -ier and the superlative removes the -y and adds -iest. For three or more syllables, the comparative uses "more" and the superlative uses "most". There are some irregular forms as well. Examples are given to illustrate the rules.
