Rule reminder
In Italian, adverbs collocate with specific adjectives and verbs. 'Profondamente convinto' (deeply convinced), 'strettamente correlato' (closely related), 'ampiamente diffuso' (widely spread), 'fortemente voluto' (strongly desired). Using the wrong adverb — even a synonym — can sound unnatural to native speakers.
