This study aims to describe and analyze Korean and Indonesian object pronouns based on a Korean-Indonesian parallel corpus. Both Korean and Indonesian are categorized as ‘discourse pro-drop languages’ that allow arguments(subjects and objects) to be dropped. However, the object elliption in Indonesian is more restrained because in independent clauses the object cannot be ommited. The results of the Korean-Indonesian parallel corpus showed that there were instances when Korean object pronouns corresponded with Indonesian object pronouns and when they did not. The Indonesian object pronoun is controlled by its verb’s transitivity and therefore can appear even when the object pronoun in the Korean text was expressed using zero anaphor. The Korean object pronoun when overtly expressed, displayed new information, focus or emphasis. In addition, we also observed cases on the account of different language expression, Korean and Indonesian preference on expression was discovered.
