From Verum to Epistemic Modality and Evidentiality : On the Emergence of the Spanish Adv+C Construction

In this article, I investigate the diachronic development of a construction in Modern Spanish. It consists of an epistemic or evidential modifier followed by the complementizer (hence Adv+C) that heads root clauses (Seguro Adv que C viene ‘Surely he/she will come’). I demonstrate that the distributional, semantic, and pragmatic properties support a monoclausal analysis for Modern Spanish Adv+C as well as for its historical source construction. I propose a cartographic analysis associating Adv+C and the source construction with a low position in Rizzi’s split CP. Supported by corpus data, I identify a verum focus construction (Aff+C) as the origin of Adv+C. I claim that the loss of the verum interpretation triggers the reanalysis of the construction. This ultimately gives rise to its productive extension to other epistemic and evidential modifiers
