What is an adverb?
An adverb is a word that we add to describe how is something or someone doing the action, is just a kind of describtion of the verb that it is following, there are adverbs of place like aquí(here) allí(there), adverbs of time like: más tarde(later).después(after).... but in this lesson we are going to talk about advebs made from adjectives, lets go to learn how:
There are some adverbs that you can create them from a adjective like bad(badly), friend(friendly), well as you can see in English language we can create them just adding "ly", in spanish language is the same but we add the letters "mente" ex:
