AdverbsAdjectives modify nouns. The 'adverb' is the catch all term that is used to refer to phrases or words that modify everything else.
Following is an adverb modifying an adjective:
Ils sont trop sophistiqués.
and an adverb modifing an entire sentence:
Heureusement, malgré que je soit pauvre, j'ai de la
nourriture, de l'eau, et un abri.
More than anything else, by modifying a verb, adverbs tell us how (i.e. the manner in which) something is done. Such adverbs are called ‘manner adverbs’
Adverbs are typically built from adjectives. The standard, most common model is constructed by appending ment to the end of the feminine adjective (Regular Adverbs).

Thankfully, not all adverbs are built the same way for things would get a little
drab. Sometimes the ment is appended to the masculine adjective (Dropped
E), sometimes not ment but mment is appended to the adjective
(Irregular Adverbs), and sometimes the
ment ending isn't used at all (Other Origins).
In English, we append ly as opposed to ment to an adjective to form a manner adverb. English speakers really love doing this and invent new adverbs all the time this way. French speakers have been more reserved about creating adverbs this way and many English ly adverbs are expressed in French using a prepositional phrase as opposed to an ment ending adverb.

Falling within the 'adverb' category are words and phrases that negate (Negations Tutorial), locate both in space (Place) and time(Time), as well as certain expressions that qualify sentences and phrases. I know this is all exciting but please try to contain your emotions.
