This case study explores the comprehension challenges related to synecdoche among EFL students at the Modern College of Business and Science (MCBS). Recognizing a gap in the literature, the study aims to understand the difficulties students face when dealing with synecdochical contexts and to identify contributing factors. Two instruments were employed: a synecdoche comprehension test and a student questionnaire, completed by 96 MCBS students. Additionally, a teacher questionnaire was administered to 10 participants to gain further insights. The results reveal a wide range of understanding, with only 31 out of 69 participants passing the comprehension test, indicating a prevalent misunderstanding of synecdochical phrases. The teachers’ questionnaire highlighted important variables affecting students’ comprehension of synecdoche. The findings suggest a need for targeted teaching strategies to improve comprehension of synecdoche among EFL students.
