This document discusses how to form comparative adjectives and adverbs in English. It explains that comparatives of equality or inequality can be formed using "as...as" or "not as...as" structures. For adjectives, short forms add "-er" and long forms use "more/less". Adjectives ending in "-y" add "-ier". Irregular adjectives like "good" have comparative forms "better/worse". Comparative adverbs are formed by adding "as" or "more/less" before the base adverb.
