Abstract
This paper aimed at identifying the significance of error analysis in written production of Ajloun National University students in English Writing 2 (Essay Writing) course in the final examination. The participants were eighteen second- year English language major students. The students were asked to choose a topic out of six different topics to write an essay in the final examination. The results showed that there were ten different types of errors categories identified in students' essays in the final examination such as word choice, spelling, punctuation, prepositions, etc. Moreover, the results revealed that the most common errors categories were wrong word choice (N=104, 18.02%) (Rank 1), followed by poor spelling (N=84, 14.55%) (Rank 2) whereas the least common types of errors categories were poor possessives usage (N=24, 4.15 %) (Rank 10) and wrong pluralism (N=29, 5.02.33%) (Rank9). Finally, identifying errors committed by ANU students were significant because they shed light on the problems that face them as well as helped the instructors in providing feedback to the students to make their writing more successful.
