Ḥurūf al-Maʿānī are essential linguistic elements that connect explicit and implicit meanings within a sentence. However, Hurūf al-Jarr (Arabic prepositions) present significant challenges for students in terms of comprehension and mastery. Since there are twenty types of Hurūf al-Jarr, each carrying diverse meanings depending on the sentence context, which function as crucial supportive factors in addressing students’ weaknesses and improving their proficiency, this study aimed to examine the level of mastery among Arabic language students in understanding the Maʿānī Hurūf al-Jarr. Additionally, this study also investigated students’ perception levels as a potential social factor to determine their correlation with the mastery of the aforementioned matter. A cross-sectional survey method was employed with a population of 100 students from the Bachelor of Arabic Language Studies programme at Universiti Sultan Zainal Abidin, enrolled in the the 9th Semester of the 2024/2025 academic session. Research instruments included a questionnaire to assess the students’ perception level and a comprehension test to measure their mastery. The reliability index of the comprehension test was 0.82, while the questionnaire had a reliability value of 0.83, as measured by Cronbach's Alpha. Data were analyzed using both descriptive and inferential methods with SPSS software. Findings revealed that students had a weak level of mastery in maʿānī ḥurūf al-jarr (mean = 50.91%) and a moderate level of perception (mean = 3.38). A positive correlation was found between the level of perception and mastery (rr = 0.257, p 0.05). These results indicate a deficiency in students’ grasp of Arabic grammar and highlight the potential value of perception as an effective factor in this area.
