With respect to this phrase marker, there are two specific questions that were subordinated earlier: 1) what is the identity of the XP projection and 2) where exactly is the subject located. In formulating potential answers to these questions I will temporarily step back from (1) in some respects in order to be able to consider a wider array of theoretical options. Ultimately, I accept an analysis that returns to and adopts the specifics of (1) with XP replaced by the familiar complementizer phrase, CP.
