Not all adjectives can be formed into adverbs; for example, the words postalmente and malatamente do not exist. On the other hand, not all Italian adverbs are formed from adjectives. When in doubt, check the dictionary.

Adverbs always precede the adjective or adverb that they modify, and they generally follow a simple verb form. For example: Beve sempre la birra. (He always drinks beer.) In sentences with compound tenses, most adverbs are placed after the past participle. For example: Sono arrivato tardi al museo. (I arrived late at the museum.) However, certain common adverbs such as già, ancora, sempre, (non)...mai, and (non)...più are inserted between the auxiliary verb and the past participle of the compound form:

Non ci sei più andata. (You don’t go there anymore.)

Enzo è sempre venuto in orario. (Enzo always came on time.)

Non ho ancora finito i miei compiti. (I still hadn’t finished my homework.)
