The document discusses how to form comparisons in English using comparative adjectives and adverbs. It explains that for one-syllable adjectives the suffix "-er" is added, for adjectives ending in "y" the "y" is dropped and "-ier" is added, and for adjectives with two or more syllables "more" is used before the adjective. The document also notes some irregular comparatives that must be memorized like "good" and "bad" as well as exceptions to the rules.
