The hidden side of adverbs

This paper will address the predicative nature of manner adverb(ial)s and of three types of sentence adverbs (subject-oriented, modal, and evaluative) in Italian. Predication often becomes overt by means of morphological correlates. Is it possible to find any such evidence with invariable adverbs? To unveil their predicative nature, a procedure will be suggested in which two sentences, one with a -mente adverb, the other with its cognate adjective (a) share the content morphemes (identity of the signifiant) and (b) entail each other (identity of the signifié as regards semantic roles). A number of such pairs will be discussed, examples of which include: Intelligentemente, Leo intervenne ‘Cleverly, Leo intervened’ and Leo fu intelligente a intervenire ‘Leo was clever to intervene’. We aim to ascertain if the argument structure of the adjective and the semantic role(s) which it assigns can shed light on the very same properties of the cognate adverb.
