The document discusses comparatives and superlatives in English. It explains how to form comparatives and superlatives of adjectives and adverbs. For comparatives of short adjectives, add "-er" and for longer adjectives use "more". Superlatives of most short adjectives add "-est" and for longer ones use "most". Irregular forms include "good-better-best" and "bad-worse-worst". The same rules generally apply to forming comparatives and superlatives of adverbs by adding "-er", "more", "-est", and "most".
