Young-Seok Choi. 1996. On the Complement of Some Unaccusative Predicates. Studies in Modern Grammatical Theories 8: 209-225. The main concern of this paper is a constraint on the complements of certain unaccusative predicates in Korean, with the primary focus on toy `become`. It will be argued that such constructions involve raising from an initially biclausal structure, consistent with Perlmutter and Postal`s (1984) hypothesis that auxiliary verbs universally occur in an initially unaccusative structure. Some syntactic evidence will be provided in support of the proposed analysis based on facts about word order, relativization, and passivization.
