In Italian, many adverbs are formed by adding the ending -mente to the singular feminine form of the adjective.

felice	felice	felicemente (happily)

If an adjective ends in -ale, -ile, or -are, the adverb is formed with the root of the adjective plus the ending -mente.

Adverbs always precede the adjective or adverb that they modify, and they generally follow a simple verb form. For example: Beve sempre la limonata. (He always drinks lemondade.) 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.)
