An adverb is an invariable word that modifies a verb, an adjective, or another adverb. Adverbs can provide additional information about manner, quantity, frequency, time, or place – they explain when, how, where, how often, or to what degree something is done. 
Adverbs of frequency express how often the action of a verb occurs. Adverbs of manner express how the action of a verb occurs. In English, the vast majority of adverbs of manner end in -ly, whereas in Italian, they mostly end in -mente. They are usually created from adjectives. 
Adverbs of place express where the action of a verb occurs. 
Adverbs of quantity express how much, how many, or to what extent. 
Adverbs of time express when the action of a verb occurs. 
Comparative adverbs are used to compare the relative superiority or inferiority of two or more things. This superior lesson will keep you from getting an inferiority complex. 😉

Negative adverbs turn affirmative statements and questions into negative statements and questions. The most common English negative adverb is the word "not," and the Italian equivalent is non. To make a statement or question negative, just put non in front of the verb.
