This is the first of a series of blog posts showing how I think about a syntax problem when I first notice it. I will occasionally choose phenomena that I notice, and talk about them in an informal fashion, breaking down the process of preliminary syntactic exploration. That is, I am just thinking off the top of my head (brainstorming), with few or no revisions. The focus of the discussion will be on process. I am not trying to come up with a polished analysis. Of course, if people suggest references for me to look at, I will look at them later, but that would be a second stage of thought, not the preliminary exploration.
