“…Some types of nonsententials are generable without the derivation of a full sentential structure, while other (apparent) nonsententials require the derivation of a full sentential structure, the unpronounced portion of which is later elided. More precisely, I will argue that as a consequence of the architecture of the independently motivated phase-based model considered here (Epstein and Seely, 1999, 2002, 2006Epstein et al, 1998), certain subsentential objects converge on their own, without being embedded in a larger structure; however, others do not. When these types of subsentential objects are Spelled Out and evaluated by the interfaces, they contain no unvalued features (which are uninterpretable at the interfaces), and so do not crash.…”
