This document discusses comparatives and superlatives in English. It explains that comparatives are used to compare two things using terms like "more" and "-er". Regular comparatives add "-er" while some adjectives like "good" are irregular. Superlatives compare three or more things and use "-est" or "most/least". They often use terms like "the" or possessives. Some common irregular superlatives are "best", "worst" and "farthest". Superlatives can also use prepositions like "in", "of" to specify groups or time periods.
