Assessing alternatives: the case of the presumptive future in Italian

In this paper, we study the distribution and interpretation of a non-temporal use of the future tense in Italian, called ‘presumptive’ or ‘epistemic’, which we label here PF. We first distinguish PF from its closest modal relatives, namely epistemic necessity/possibility/likelihood modals, as well as weak necessity modals. We then propose an account of PF in declaratives and interrogatives that treats it as a special comparative subjective likelihood modal, and test its empirical predictions. A theoretical lesson drawn from this detailed study of the semantics of PF is that semantics needs sharpened theoretical tools to be able to capture the fine-grained distinctions languages make when it comes to signaling modulated epistemic commitment to a proposition.
