Many adverbs have a comparative and superlative degree, just like adjectives.
They can have the comparative and superlative:
- Most adverbs of manner: chiaramente, velocemente, bene, ecc.
- Some verbs of place: vicino, lonatno,ecc.
- Some adverbs of time: presto, tardi, ecc.
The comparative degree of majority is formed with più combined with the simple adverb:
- Chiaramente >> più chiaramente.
- Tardi >> più tardi.
The comparative degree of minority is formed with meno combined with the simple adverb:
- Chiaramente >> meno chiaramente.
- Tardi >> meno tardi.
The superlative degree can be formed in different ways:
- With adverbs made up of simple words (like vicino, lontano, presto, tardi), the suffix -issimo is added to the end of the word: vicino >> vicinissimo; lontano >> lontanisssimo; presto >> prestissimo, tardi >> tardisssimo.
- In adverbs formed with the suffix -mente, adding the suffix -mente to the feminine superlative form of the corresponding adjective: chiaramente >> chiarissimamente; veloce >> velocissimamente.
- With all adverbs, following the comparative degree of majority of the adverb with possibile: il più vicino possibile; il più chiaramente possibile.
The adverbs bene, male, molto, poco have particular comparative and superlative forms, like the corresponding adjectives:
| Adverb | Superlative | Comparative |
| Bene Male Molto Poco Grandemente | meglio peggio più meno maggiormente | benissimo/ottimamente malissimo/pessimamente moltissimo pochissimo massimamente/sommamente |
