ABSTRACT This study investigates the lexical errors made by fourth-semester students at UIN S.M.D.D Bukittinggi when translating English texts into Indonesian, employing a qualitative case study approach. A sample of ten informants was selected through homogeneous sampling to ensure consistency in language proficiency and educational background. Data were collected through document analysis of translation tests, focusing on a news article titled "Drink Driver Jailed for Killing Retired Teacher" from BBC News. The analysis utilized James' taxonomy of formal and semantic errors, along with Ellis' error analysis procedures, to categorize the errors and explore their underlying causes, including interlingual and intralingual transfer.The findings revealed a range of lexical errors, categorized into formal and semantic errors. Formal errors included misselection and misformation, with specific issues related to incorrect suffix and prefix usage, as well as phonetic inaccuracies. Semantic errors encompassed confusion in sense relations and collocational errors, indicating challenges in selecting semantically appropriate terms. For instance, common missteps involved translating "retired teacher" as "guru pensiun" instead of the more accurate "guru yang telah pensiun," highlighting a lack of morphological precision.The analysis underscores the importance of targeted educational interventions aimed at improving students' translation skills and language proficiency. By identifying and addressing these lexical errors, the study contributes to the understanding of translation challenges faced by Indonesian EFL learners and emphasizes the need for enhanced training in morphological accuracy and semantic selection. Overall, the findings provide insights for educators to refine teaching strategies and improve translation competencies in English-to-Indonesian contexts.
