%0 Journal Article %T Sobre la estructura sintagm¨¢tica de la aposici¨®n explicativa ON THE PHRASE STRUCTURE OF THE EXPLICATIVE APPOSITION %A Carlos Mu£¿oz P¨¦rez %J Bolet¨ªn de Filolog¨ªa %D 2012 %I Universidad de Chile %X El presente trabajo pretende evaluar la adecuaci¨®n de dos tipos de an¨¢lisis de las estructuras apositivas explicativas: los an¨¢lisis sim¨¦tricos y los an¨¢lisis asim¨¦tricos. Asumiendo como marco te¨®rico la gram¨¢tica generativa contempor¨¢nea, se muestra c¨®mo los an¨¢lisis sim¨¦tricos requieren tomar supuestos fuertes con respecto a la naturaleza de la sintaxis. Por tanto, se presenta un an¨¢lisis asim¨¦trico basado en una relaci¨®n sim¨¦trica subyacente. Esta propuesta permite salvar los problemas conceptuales del an¨¢lisis sim¨¦trico, a la vez que permite explicar (i) la naturaleza predicativa de la aposici¨®n explicativa, (ii) su car¨¢cter speaker-oriented, (iii) la condici¨®n de adyacencia entre ambas partes de la aposici¨®n, (iv) la presencia de adverbios entre ambas partes de la aposici¨®n, y (v) el alcance dispar de cuantificadores en ambos t¨¦rminos de la aposici¨®n. The present paper aims to evaluate the adequacy of two types of analysis of appositive constructions: the symmetric and asymmetric analysis. Grounded in contemporary generative grammar, it is shown that the symmetric analysis requires taking several assumptions about the nature of syntax. Thus, an asymmetric analysis is presented based on an underlying symmetric relation between both parts of the apposition. This proposal neutralizes the conceptual problems of a symmetric approach and, at the same time, permits to explain (i) the predicative nature of explicative appositions, (ii) its speaker-oriented character, (iii) the adjacency condition between both parts of appositive constructions, (iv) the presence of adverbs between both parts of the apposition, and (v) the difference on scope relations between quantifiers on both parts of the apposition. %K gram¨¢tica generativa %K aposici¨®n explicativa %K ensamble sim¨¦trico %K etiquetamiento %K generative grammar %K explicative apposition %K symmetrical merge %K labeling %U http://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0718-93032012000200005
