- The present study investigated differences in rhetorical preferences in L2 writings among different L1 groups. This study compared the use of metadiscourse markers in L2 essays and identified discourse devices used to distinguish different L1 groups. The essays originated from the International Corpus Network of Asian Learners of English (ICNALE) compared six L1 groups (viz., Chinese, Indonesian, Japanese, Korean, Taiwanese, and Thai) based on the frequency of metadiscourse markers. I utilized heat map with hierarchical clustering to investigate differences in metadiscourse among the six learner groups. The results suggested a substantial difference in the use of metadiscourse markers between East Asian groups (viz., Chinese, Japanese, Korean, and Taiwanese) and Southeast Asian groups (viz., Indonesian and Thai). Furthermore, each learner group displayed the specific characteristics of metadiscourse, which offer suggestions for improving L2 learners’ writings.
