An adverb (avverbio) is a word that modifies a verb, an adjective, or another adverb. In English, adverbs are often formed by adding the suffix -ly to adjectives: slowly, softly, surely. Adverbs often answer the question come? (how?), quando? (when?), or dove? (where?):

Luciano agisce lentamente. (Luciano acts slowly.)

Leonardo viene tardi. (Leonardo comes late.)

Usciamo adesso. (We’re leaving now.)

Ci andiamo a giugno. (We are going there in June.)

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

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