The purpose of this article is to show that, even in a language like Japanese which lacks overt morphological agreement, Agreement Phrases not only exist, but also play an important role in the grammar. Evidence comes primarily from facts about scope interaction in certain complex predicate constructions. The article also presents indirect support for the core idea of Watanabe's (1993) three-layered Case theory.Since Pollock (1989) and Chomsky (1991), much work has been done on the Split Infl Hypothesis, according to which traditional Infl should be decomposed into several different syntactic categories including Tense and Agreement. There is, however, little agreement as to whether languages without overt agreement morphology have Agreement Phrases as characterized in , and two anonymous TLR reviewers. 2. In this paper, we will not be concerned with subject positions. Thus, they are not represented in structural descriptions (tree diagrams, etc.). For a recent discussion on subject positions, see Koizumi (1995).

If Case is an LF requirement (and not an overt one), word order facts would not provide us with such information anyway (Howard Lasnik, personal communication).Brought to you by |
