An adverb is a word that qualifies the action of the verb, that is, it specifies how or when the action is performed. In English, many adverbs are indicated by the -ly ending. In French, most adverbs end in -ment:
Adverbs answer questions about the action: how? How much? When? And where? While most adverbs in French and English modify verbs, they can also modify other adverbs as well as adjectives.
|verb modified by adverb:||écoute attentivement||listen carefully|
|adverb modified by adverb:||trop lentement||too slowly|
|adjective modified by adverb:||extrêmement silencieux||extremely quiet|
Note: It is common in non-standard English for speakers to use adjectives in place of adverbs.
