“…This is perhaps because the fourth-year learners have more experience in learning vocabulary knowledge, which is consistent with previous findings suggesting that understanding the aspects of vocabulary knowledge requires sufficient language experience (e.g., Hayashi & Murphy, 2011;Schmitt & Zimmerman, 2002, Nontasee & Sukying, 2021a. Diao (2004) also found that senior students showed better collocation competence than freshmen students, likely due to the senior students having more exposure to English, and other studies have also reported that students' knowledge of collocations improves through their academic years (Al-Zahrani 1998;Ebrahimi-Bazzaz et al, 2014;Gitsaki, 1999). The results also indicate that, overall, collocational competence for both first-and fourth-year students is unsatisfactory and students showed poor collocational knowledge in general.…”
