: Peer review plays a vital and major role to determine the fate of manuscripts submitted to international academic journals. The present study analyzed the discourse structure and the language use of a corpus containing 43 peer review reports from journals from three disciplines (i.e., Applied Linguistics, Accounting, and Sociology). This study analyzed the most frequent discourse moves, negative, and positive expressions used in minor revisions, major revisions, and rejected manuscripts. The findings of this study showed that all discourse moves appeared in all peer review reports but two moves “Summarizing Judgment” and “Conclusion and Recommendation” were the most frequent discourse moves in all peer-review categories. The findings also revealed that the words “well”, “good”, and “original” were the most frequently-used positive words, while the words “unclear”, “inconsistent”, and “poor” were the most frequently-used negative words in the analyzed peer-review reports. The study recommends some points to be considered in future research on this topic.
