Kim, Hak-Youn. 1996. A Study on Locality and Binding. Studies in Modern Grammatical Theories 8: 181-2O8. The purpose of this paper is to show how Locality (Manzini 1992) can solve the problems revealed in the previous Binding Theories (Chomsky 1981, 1986b, Aoun 1986), and furthermore to explain even every dependency. For the dependency of wh-movement, the Locality employs both categorial sequence based on non K-governing and address sequence based on K-governing, and barrier defined by g-marking. If the sequence satisfy government, then wh-antecedents and the traces establish dependency. This Locality accounts for wh-t incorporated in Generalized Binding and even Specific islands. For A-movement dependency, the theouy makes use of Barrier suggested above and extended the trace to dependent element. In addition, this rule is bicotditioned. Through optional g-marking forBarrier, the problem of non complementary distribution of pronoun and anaphor are solved. In conclusion, the Locality has strong explanatory power because the simple principle can cover various problems revealed in previous binding theories.
