This document discusses the different forms that adjectives can take when used in a comparative structure. It outlines five rules for comparative adjectives: 1) adding -ER to short adjectives, 2) repeating the last consonant and adding -ER for short adjectives ending in a consonant and vowel, 3) removing the final Y and adding -IER for adjectives ending in Y, 4) adding MORE before long adjectives, and 5) IRREGULAR adjectives like GOOD and BAD which take different forms. The purpose is to compare one thing to another using the proper comparative adjective structure.
