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 "better", "worse", and "furthest". The same rules generally apply to forming comparative and superlative adverbs by adding "-er", "more", "-est", and "most".
