Las oraciones escindidas como casos de inversión copulativa
Abstract: In this paper I will present my analysis of cleft sentences as cases of copular inversion (Alsina, 2007; Moro, 1997). According to my hypothesis, the postcopular element in a sentence like “Son los niños quienes fueron al parque” should not be considered the subject, but the predicate, as the apparent agreement is explicable by the principles governing copular inversion proposed by Alsina (2007). However, the lack of agreement when the obligatory preposition “a” for animated objects (“Es/*son a los niños a quienes vi”) is due to a general principle of language that prohibits agreement between elements in different cases. As this “blocking-by-case” principle conflicts directly against the agreement-per-coindexation principles required to understand copular inversion, an Optimality Theoretic version of LFG is used as theoretical framework. Finally, discussion of German and Dutch data will show the possible extension of this proposal to other languages that also show copular inversion.
