Le-predicates and argument structure in Mexican Spanish Ía Navarro Ibarra In this talk I will present a process of complex predicate formation in Mexican Spanish that consists in combining a non-referential le clitic form and a verbal base (cf. (1)a-c). I will focus on the syntactic and semantic properties of the lexical structure of the verbal bases. The goal of the talk is to identify the relevant components of the argument structure that are involved in the complex predicate formation and to formally account for the complex predicate composition. (1) a. ¿Le cierro a la puerta? Es que entra mucho aire. LE close at the door.OBL Is that enter much wind. “Do I close-le at the door? There is a lot of wind coming in.” b. Todavía hay que caminarle un rato. Yet there-is that to-walkLE a while. “We still must walk-le for a while.” c. Este fin que viene sí le salimos. This week-end that comes AFIRM LE go-out. “Next weekend we do go out-le.” My analysis is built on following assumptions: (i) both the configurational semantics (i.e. l(exico)-syntactic structure) and the non-configurational semantics (i.e. the semantic conceptual values associated whit the l-syntactic projections) are the significant elements that define the grammatical meaning of the verbs (Mateu 2002). (ii) The le clitic has grammaticalized a non-referential abstract goal and some agentive implications that are typically associated with the Dative (Company Company 2006 inter alia). (iii) The use of le in complex predicates results from two bleaching processes: weakening of argument status and weakening of pronominal status (Torres Cacoullos 2002). The following points are central in this analysis: a) Following Cuervo (2003), we affirm that as a consequence of (ii) and (iii) the syntactic status of le changes to that of a defective High Applicative Head. This head introduce a function that relates the denotation of le (i.e. the non-referential abstract goal and the presupposition of an agent) with an event denoted by a VP. b) Complex predicates with le are formed when the clitic head takes a VP as its complement and introduces an event modification by means of a semantic composition process based on pseudo-incorporation (cf. Dayal 2003, Espinal & McNally 2007). c) Complex predicates with le denote agentive and intransitive activities, even if the verbal base is transitive or unaccusative. I will argue that this because the highest verbal node in the syntactic structure, which is the complement of the clitic ApplP, must have a semantic component compatible with the denotation of activities and with an abstract goal inference (This structure is represented in (2)).
