摘要:This study reports on research article (RA) authors’ definitional understanding and sociocultural perceptions of intertextuality and plagiarism in academic writing. To meet this end, a questionnaire, consisting of three sections, was constructed and emailed to Iranian RA authors who have published in leading international and local applied linguistics journals. The findings of the first two sections suggest that authors recognized the crucial role intertextuality plays in RAs; however, they had a flimsy understanding of the concept and its cultural bearings. On the other hand, unacceptable, as most of these respondents may find it, plagiarism was seen as an unavoidable part of academic research at least in initial steps of academic writing. This was shown to be mainly the function of the authors’ sociocultural perceptions of plagiarism. The third section of the questionnaire addressed the authors’ departure from plagiarism and gradual proximization to intertextuality. The findings imply that plagiarism, intertextuality and their concomitant sociocultural perceptions ought to be discussed, re-examined, and put to trial in local contexts
