Analyzing Linguistic Errors in Writing an English Letter: A Case Study of Indonesian Undergraduate Students

This paper seeks to explore errors in Indonesian students’ writing in English. Seventy five students in their second year of study at the Department of English Literature, Faculty of Letters, Methodist University of Indonesia, Medan, were involved in this study. Despite the fact that they have studied grammar in the first semester at the University and several years in High School, students still face problems in writing in English. This study will elaborate on types of errors on students’ writing so as to make them aware of each type of errors before composing a text in English. In gathering the data needed, students were asked to write a letter with a maximum of 90 words to a property agent requesting for a specific home they wish to buy. Their writings afterwards were analyzed in terms of linguistic errors as proposed by Hubbard et al. (1996). These include grammatical, syntactic, substance, and lexical errors. This study revealed that students committed 42.4% of grammatical errors, 26.7% of syntactic errors, 17.9% of substance errors, 13% of lexical errors. Based on the discussion of the findings, it is concluded that Indonesian students in this study committed a great number of errors due to first language transfer.
