It has been a common view in the literature since Yang (1984, 1988) that caki ‘self' is a long distance anaphor, subject to parameterizaton of the binding domain across languages. I suggest that caki ’self' is a local anaphor with a DP structure including pro. I also suggest that a null argument in Korean has a DP structure with pro, too, based on the wide range of similarities with caki ‘self.' The present proposal for caki ’self' and the null argument has a nontrivial theoretical implication for anaphors and null arguments in languages typologically akin to Korean.
