Academic authors employ various language means in order to construct and disseminate knowledge, to sound persuasive, to undergird their arguments, but also to seek agreement within the academic community. The aim of this paper is to analyse a selected group of rhetorical strategies used by Anglophone and Czech authors of Linguistics research articles (RAs) and research theses (RTs). These strategies are assumed to vary in both academic genres since the position of their writers within the academic community differs. Even though authors of RAs have to meet reviewers’ requirements in order for their article to be published, so their relative position may be lower than that of the reviewers’, authors of RAs may have the same “absolute status” as the reviewers may be just as expert in that particular field. By contrast, the status of research students is lower than that of their evaluators both in relative and absolute terms. Even though students may gain some learned authority in presenting an original contribution, their assessors command both learned and institutional authority, hence are endowed with a higher status. Apart from comparing rhetorical strategies used in RAs and RTs, the paper focuses on cross-cultural differences between Anglophone and Czechacademic writing traditions.
