“…As reported in a series of previous studies, students' difficulties in using English collocations mainly resulted from their L1s' negative transfer (Begagić, 2014;Boonraksa & Naisena, 2022;Fan, 2009;Osman & Abdalla, 2019;Phoocharoensil, 2011Phoocharoensil, , 2014Yamashita & Jiang, 2010;Yumanee & Phoocharoensil, 2013). Another leading cause of students' misuse or incorrect choices of English collocations was due to their lack of appropriate collocational knowledge (Boonraksa & Naisena, 2022;Detdamrongpreecha, 2014;Dokchandra's 2019;Duong & Nguyen, 2021;Fan, 2009;Namvar, 2012;Saud, 2018;Yumanee & Phoocharoensil, 2013). In addition, there have been a set of research findings which pointed out that synonymy strategy was one of the underlying factors giving rise to students' inappropriate use of English collocations (Boonyasaquan, 2006;Kuo, 2009;Mongkolchai, 2008;Phoocharoensil, 2011;Zughoul & Abdul-Fattah, 2001).…”
