How the suffix ly works

Adding ly to most adjectives creates an adverb that describes how, when, or to what degree something happens, as in quick becoming quickly. This pattern is common but not universal, since a handful of ly words such as friendly and lonely are actually adjectives, not adverbs. Reading the word in a sentence usually makes its role clear, since adverbs typically modify verbs while these adjectives describe people or things directly.
