El desarrollo diacrónico de la construcción disponerse a + INF.

In this paper, the historical development of the construction disponerse a + INF is analyzed, as a carrier of an aspectual value of imminence. Specifically, those lexical-grammatical criteria that allow observing the process of grammaticalization and constructionalization of the scheme are explored. In addition, the semantic expansion from the imminent value to the inchoative and causative value is studied. Throughout the paper, contrasts are made with the diachronic trajectory of poner(se), since this form has exerted an analogical influence on disponer(se). From a theoretical perspective, it interacts with the model of grammaticalization and with the constructions grammar applied to the historical study of verbal periphrasis. At the methodological level, the research is based on the elaboration of a database with the integral registry of the examples from CORDE, which allows projecting quantitative as well as qualitative linguistic analyzes. As a result, the grade of grammaticalization and constructionalization of the item is described, the chronology of its imminence, inchoative and causative values are explored, and the proximity of the construction with the paradigm of aspectual verbal periphrasis is reflected.
