Opacity in agreement

In this paper, I use a complex pattern of agreement in progressives in the NeoAramaic language Senaya as a window into the timing of and relationship among the different components of ^-agreement. In particular, I argue that we need to recognize three distinct, ordered operations underlying what we see on the surface as ^-agreement - Match, Value, and Vocabulary Insertion - based on data that reveal that opacity can arise both in the relation between Match and Value, as well as in the relation between Value and Vocabulary Insertion. This work builds on and extends earlier research that recognizes the need for (at least a subset of) these distinct components, including (among many others) Halle & Marantz (1993; 1994), Béjar (2003), Arregi & Nevins (2012), Bhatt & Walkow (2013), Bonet (2013), and Marušič et al. (2015).
