Phrase Structure and Movement in Japanese
Japanese exhibits some unique features with respect to phrase structure and movement. It is well-known that its phrase structure is strictly head-final. It also provides ample evidence that a sentence may have more complex structure than its surface form suggests. Causative sentences are the best-known example of this. They appear to be simple sentences with verbs accompanying the causative suffix, -sase. But the causative suffix is an independent verb and takes a small clause vP complement in the syntactic representation. Japanese sentences can have a rich structure in the right periphery. For example, embedded clauses may contain up to three overt complementizers, corresponding to Finite (no), Interrogative (ka), and Report/Force (to). Matrix clauses may end in a sequence of discourse particles, such as wa, yo, and ne. Each of the complementizers and discourse particles has a selectional requirement of its own. More research is required to settle on the functional heads in the nominal structure. Among the controversial issues are whether D is present and whether Case markers should be analyzed as independent heads. Various kinds of movement operations are observed in the language. NP-movement to the subject position takes place in passive and unaccusative sentences, and clausal comparatives and clefts are derived by operator-movement. Scrambling is a unique movement operation that should be distinguished from both NP-movement and operator-movement. It does not establish operator-variable relations but is not subject to the locality requirements imposed on NP-movement. It cannot be PF-movement as it creates new binding possibilities. It is still debated whether head movement, for example, the movement of verb to tense, takes place in the language.
