This document discusses how to form comparative adjectives in English. It explains that one-syllable adjectives add "-er", two-syllable adjectives ending in "-y" change the "-y" to "-i" and add "-er", and adjectives with three or more syllables use "more" before the adjective. It provides examples of comparisons using these rules and notes some irregular adjectives like "good", "bad", and "much" that have different comparative forms.
