The present study attempts to analyze and classify errors in translations of Korean Mongolian language learners and to suggest educational implications based on the error analysis. Korea and Mongolia have had an established relationship since 1990 and held exchanges in various fields for a short period of time, and as a result the demand for professional translation is increasing. To meet this demand, undergraduate schools also require educational programs for professional translators, yet it is difficult to find any research or studies about the issue. In this study, Mongolian texts translated by Korean Mongolian learners were collected and analyzed, and the errors were classified into 1) grammar related errors, 2) translation skill related errors, and 3) meaning related errors. Based on the analysis, the following implications can be presented. First, it is necessary for students to recognize the differences between the use of punctuation marks in the two languages and to learn how those them appropriately in the target language. Second, there is the issue of transcribing Mongolian into Korean. Although precise common rules for transcribing have not yet been established, teachers should suggest a consistent transcription guide. Third, since many errors related to the source language appear, it is necessary to avoid literal translations and complete the translation suitable for the target language. Finally, students need to be exposed to various types of texts and practice the style of writing that fits to the text.
