The syntax-phonology interface of Left Branch Extraction
Locality of dislocation has been one of the central issues in linguistics since Ross’s (1967. Constraints on variables in syntax. Cambridge, MA: MIT dissertation) seminal paper. One of the locality conditions that Ross describes is the Left Branch Condition, which prohibits the left-branching element in a nominal domain from being extracted. However, Bošković (2005. Left branch extraction, structure of NP, and scrambling. In Joachim Sabel & Mamor…

The Comparative Syntax of Evidential Markers in Korean and Japanese
The cartographic project, initiated by Rizzi (1997, 2004, 2013) and Cinque (1999, 2004, 2006), among others, aims to provide a detailed map of clause structure for human language. The core proposal is that the traditional TP and CP consist of a hierarchy of functional projections that is supposed to be universal across languages. Recently, building on Cinque (2004), An (2022a) shows that evidential markers in Korean and Italian, namely, pota and …

Syntactic Head Movement in Japanese
We investigate the syntax of verb-echo answers in Japanese. We first present two arguments showing that this answer form is best analyzed through overt V-to-T-to-C movement, followed by TP-ellipsis. We further show that verb-echo answers exhibit a scope reversal effect: the otherwise robust wide scope reading of focus-marked phrases with respect to negation is reversed in this construction, a pattern that holds across all grammatical positions. T…
Particle stranding ellipsis involves PF-deletion
Argument Ellipsis and Scope Economy in Japanese
In this article, I show that in Japanese, while some focus elements obligatorily take wide scope with respect to scope-bearing predicative heads, argument ellipsis reverses this scope possibility, so that narrow-scope interpretation of the focus element is obligatory. I further show that Scope Parallelism (Fox 2000) overrides this narrow-scope requirement for elided arguments; when the antecedent clause exhibits scope interaction, the elided clau…
