Inconsistencies with respect to infinitive marker to
Just to clarify, there are a couple of inconsistencies with respect to how I drew the trees with the infinitive marker to on some of the handouts. Specifically, there are slides here and there where to is drawn into the trees as if it were T—rather than an M that moves up to T. The official version of the theory we’re working with (and different from what is in the textbook) is that to is an M that moves up to T, just as in the homework problem from a few weeks ago. So, if you see somewhere to given as being a T, just think of it as a shorthand for a T that takes an MP complement, headed by the M to, which has moved up to T. I’ll try to catch this in future handouts, but I still might miss one here and there.
[Edit after original post: Part of the point of that homework was showing that to doesn’t in fact move up to T.]
