This course is a detailed investigation of the major issues and problems in the study of lexical argument structure and how it determines syntactic structure. Its empirical scope is along three dimensions: typology, lexical class, and theoretical framework. The range of linguistic types include English, Japanese, Navajo, and Warlpiri. Lexical classes include those of Levin's English Verb Classes and others producing emerging work on diverse languages. The theoretical emphasis of this course is on structural relations among elements of argument structure.
