The CUC in the MP Revisited

The CUC in the MP Revisited

This paper began with pointing with the theoretical weaknesses of the Chain Uniformity Condition (CUC) which is based on the uniformity condition (Chomsky, 1992; Chomsky & Lasnik, 1993). To solve the problems, I introduced the refined CUC and Barriers with a new adjunction condition that is adopted from Frampton (1990). Concerning the problems raised by subject/object asymmetry and Wh-in-situ constructions, I have introduced a [+p] feature (Watanabe, 1991). In order to develop a more general theory, I have separated the I-to-C Raising (or [T+AGRs]-to-C Raising) into two parts: the one part occurring before Spell-Out by [+p], and the other after Spell-Out by [T+AGRs]. I assumed that erasure of offending traces in the Spec of AGRsP in the overt syntax through L-marking by [+p] does not influence the judgement of grammaticality at all. I have shown that with the help of the constraints developed in this paper we can explain the cases of the movement of Wh-in-situ at LF.
