This study provides a critical discourse analysis of letters of complaint by Jordanian university students. It aims to investigate the rhetorical pattern in these letters and explore the main strategies students use to express their dissatisfaction about certain issues and persuade the addressee to take action. To this end, permissions were obtained to collect data from two universities in Jordan: Jordan University of Science and Technology and World University of Islamic Studies and Education. The data were analyzed both qualitatively and (...) quantitatively through two analytic frameworks within critical discourse analysis : genre analysis to investigate the rhetorical pattern of complaint letters, and discursive analysis to investigate the main strategies of persuasion. These strategies were then categorized according to Aristotle’s means of persuasion: ‘ethos’, ‘logos’ and ‘pathos’. The analysis showed that written complaint was a distinctive genre with distinctive moves. It also revealed that persuasion by means of pathos was more prevalent than the other two types. Socio-cultural values have been shown to be so powerful in Jordanian society even in neutral situations such as academic context. This study will hopefully contribute to the fields of genre analysis and CDA in cross-cultural communication. (shrink)
