The document discusses comparative and superlative adjectives. It explains that the comparative form compares two people or things, while the superlative compares one person or thing to a group. For one-syllable adjectives, -er is added for comparative and -est for superlative. For adjectives with more than one syllable, "more" is used for comparative and "most" for superlative. Some adjectives like good, bad, many and little are irregular.
