Adverbs are very similar to the adjective in that, in general, they behave similarly with respect to the verb as the adjective does with respect to the noun.
``Una parola dolce'' A/ns
versus
``Parlare dolcemente'' B/
In traditional Italian grammar, adverbs are subdivided into different subcategories on the basis of their semantic value: manner, time, place, quantity, comparative, affirmative, negative, relative/interrogative, etc.
In corpus tagging and dictionary encoding, not all these types are distinguished.
