This document discusses how to form and use superlatives in English. It explains that to form most superlatives, -est is added to the adjective. Superlatives are used to compare more than two things and often use "the" and "in" or "of". Irregular superlatives like best, worst, and furthest are also covered. For adjectives with two or more syllables, "the most" is used instead of adding -est. Examples are provided to illustrate superlative usage.
