This paper addresses the problem of the distribution and interpretation of the Korean long-distance anaphor "caki" and its pronominal counterpart "ku." The first part of the paper reviews previous analyses and shows that the distribution of "caki" and "ku" cannot be fully accounted for in purely structural terms. An alternative analysis is provided within the neo-Gricean theory of implicature. Finally a discussion is provided of some cases where "caki" and "ku" appear to be in free variation. The account provided in this paper, it is argued, can be generalized to cover these cases as well. (Author/JL)
