Since Ross (1969), it is well known that certain island violations are ameliorated in Sluicing in English. Merchant (2001) argues that the amelioration effects obtain, since certain islands are PF-islands and thus can be repaired by ellipsis at PF. However, amelioration of island effects is not universally observed. For instance, Korean Sluicing is island-sensitive, as well as Japanese Sluicing. This might lead to the hypothesis that in Korean/Japanese, islands are not PF-islands but LF-islands and thus cannot be repaired by ellipsis. However, this paper rejects the hypothesis by demonstrating that in fragment answers in Korean, island violations can be repaired by ellipsis at PF. The paper also suggests a possible direction towards an account for the island sensitivity in Korean Sluicing.
