Just like we have an adjective to describe a Noun we have an adverb describing a verb. To be further elaborative, the Adverb describes how a certain action is being done. For example, Madhuri was sleeping peacefully. Here, the word PEACEFULLY describes how Madhuri was sleeping, which is the action done by Madhuri. Usually, Adverbs end with ‘ly’ and it answers the questions where? When? How? And to what extent?
