Funktionsverbgefüge y predicados complejos en espa？ol: Una nueva interpretación a partir de proyecciones sintácticas metafóricas

in the last few years modern linguistics continues to multiply the number of concepts and terms about expressions considered by traditional grammar as simple "locutions" and based on diachronic and frequency criteria. this expansion leans on concepts of questionable theoretical applicability as "grammaticalization" or "lexicalization", distorting the reality of the problem. this work aims at revising the main constructions classified in a general way as "idiomatic expressions", under which we can find a group of denominations defined by apparent linguistic criteria (collocation, funktionsverbgefüge, complex predicates, etc.). we propose to reduce considerably the number of these concepts helped by premises of the valence grammar and adding the idea of "re-syntactic process", that is, a phenomenon that converts a basic structure into another of metaphoric type and where a new productive structure will be created.
