This study explores variation in the use of citations in a specialised corpus of Linguistics research articles comprising Czech-medium and English-medium texts by Czech linguists and English-medium texts by Anglophone authors. Drawing on the typologies suggested by Thompson and Tribble (2001), Petrić (2007) and Dontcheva-Navratilova (2016), the investigation aims at identifying the frequency and rhetorical functions of citations across the generic moves of RAs and exploring how they contribute to academic persuasion. The findings of the contrastive analysis indicate that the existing divergences in citation practices of Czech writers writing in Czech and English and Anglophone authors are related to the intended readership and the linguacultural context in which they strive to convince readers to accept their claims and views.
