Question

What is an adverb I always get mixed up with these

Answer 1

A word that describes a verb and it usually ends in ly

Answer 2

An adverb tells you when, where, how, in what manner, or to what extent an action is performed.

Many adverbs end in ly (most of them that are used to show how an action is performed).

Even though many adverbs end  with ly, some do not.
