This document discusses how to form adverbs from adjectives in Spanish. In most cases, an adverb is formed by adding "-ly" to an adjective. However, if the adjective ends in "-y," the "y" is replaced with "i" before adding "-ly." If the adjective ends in "-able," "-ible," or "-le," the final "e" is replaced with "y" before adding "-ly." For adjectives ending in "-ic," "-ally" is added. Some adjectives are identical to their adverb forms, such as "fast" and "hard." The adverb that corresponds to the adjective "good" is "well."
