This document provides rules for forming comparative and superlative adjectives in English. It explains that comparative adjectives are used to compare two things and use endings like "-er" or "than". Superlative adjectives compare more than two things and use endings like "-est" or "the most". The rules provided give guidance on adding suffixes based on the number of syllables in the adjective and whether it ends in certain letter combinations. Exceptions for irregular adjectives are also noted. The purpose is to help readers properly form comparative and superlative adjectives.
