This document discusses the formation of adverbs in English. It explains that most adverbs of manner are formed by adding "-ly" to adjectives. However, adjectives ending in "-ly" cannot have "-ly" added. In those cases, adverbs are formed in a descriptive way using words like "way" or "manner". The document also notes some adjectives that can form adverbs in two ways, changing the meaning, and exceptions with verbs like "be" where adverbs are not used. It provides examples and an exercise to underline the correct adjective or adverb form.
