This document provides instructions for forming comparative adjectives in English. It discusses adding "-er" to one-syllable adjectives, using "more" with two-syllable adjectives and those ending in "-ed" or "-ing", and lists some irregular comparatives like "good" and "bad". The goal is to understand how to correctly change adjectives to their comparative form using suffixes and auxiliary verbs.
