Abstract
This paper examines two problems concerning relativization that have remained unaccounted for in syntactic research: i) the lack of reconstruction effects of the relative head in wh-relatives; and ii) the source of the choice of a complementizer C/that or wh-relative pronoun. The primary aim of this study is to provide a detailed explanation for these problems, using the general approach to relativization, Tonoike's (2008) DP movement approach, with necessary elaboration added. The description of the elaboration is twofold: concerning problem (i), we adopt the Late Merge Strategy of Takahashi (2016); and concerning problem (ii), it is proposed that the partitive Case feature assignment is a deciding factor executed in parallel with the case of the relativization of the existential there subject.
