This document discusses adverbs of manner and how they are formed from adjectives. It notes that adverbs of manner add details to verbs by describing how an action is performed. Adverbs are often formed from adjectives by adding "-ly" to the end, though if the adjective ends in "y", the "y" changes to "i" before adding "-ly". Examples are given of common adverbs like "quickly" and "happily". The document then provides a game to practice identifying adverbs of manner in sentences.
