Verb Doubling

AbstractThe analysis offered in “Verb doubling construction in Japanese” is critically reviewed. The analysis yield verb doubling construction (VCD) by moving a verb-tense complex (VTC) in T to C, and phonetically realizing both the moved VTC in C and its copy in T. The analysis suffers from various shortcomings. Among them, it relies upon a problematic formulation of Doubly Filled Comp Filter, and the analysis incorrectly predicts the possibility of VDC in embedded contexts. The present study offers a brief outline of a plausible alternative of VDC that involves a phonetically null sentence-final particle (SFP) whose phonetic content is copied from the predicate at the phonetic interface.

Effective Use

We construct vertex transitive lattices on products of trees of arbitrary dimension [Formula: see text] based on quaternion algebras over global fields with exactly two ramified places. Starting from arithmetic examples, we find non-residually finite groups generalizing earlier results of Wise, Burger and Mozes to higher dimension. We make effective use of the combinatorial language of cubical sets and the doubling construction generalized to arbitrary dimension. Congruence subgroups of these quaternion lattices yield explicit cubical Ramanujan complexes, a higher-dimensional cubical version of Ramanujan graphs (optimal expanders).

Person Agreement

The paper describes the doubling of free personal pronouns in Agul, an East Caucasian language spoken in Daghestan, Russia. The doubling construction consists of a subject pronoun in the canonical preverbal position, paired with an identical instance of the same pronoun immediately following the verb. The first pronoun is usually adjacent to the “verb–pronoun” combination, though it can optionally be separated by another constituent. In the oral corpus consulted for the analysis, the construction is found most often with the primary verb of speech in clauses introducing a quote (e.g. ‘I said I, …’). I argue that the doubling pattern originated as the conflation of a preverbal subject with a very frequent “verb–subject” word order used with highly topical referents. The function of the doubling construction is therefore postulated to draw additional attention to the referent. A brief comparison of Agul doubling and related phenomena in other languages (e.g. person agreement and clitic doubling) is also offered.

Doubling Construction

This paper argues that the ban on headless XP-movement should not be captured in narrow syntactic terms. That is, there is no constraint in the syntactic computation preventing remnant movement of a phrase from which the head has been extracted, i.e., so-called Takano’s Generalization is wrong. This is demonstrated through a case study of the emphatic doubling construction in Rioplatense Spanish, which requires a derivation proceeding exactly along these lines. It is further argued that the relevant prohibition should be stated as a condition that applies at PF: A preliminary conjecture on the nature of this prohibition is also offered.
