Despite the voluminous body of research investigating linguistic, disciplinary, and cultural variations in citation practices in research articles, these practices have not been examined in light of the interplay between disciplinary conventions and research methodological underpinnings in the field of linguistics. Adopting a multi-faceted design, this study analyzed 180 research article introductions from two close-knit disciplines (Theoretical Linguistics and Applied Linguistics) to look into the contextualized citation functions and authorial evaluative stance toward citations. The corpus was purposively selected to sample three research methodologies. Comparisons were carried out at disciplinary, research methodological, and combinatory levels. The findings of the study show clear variations in the citation functions and evaluative stances taken toward citations. These variations are thought to be the result of the disciplinary conventions which authors must abide by as well as the paradigmatic underpinnings of the research methodologies which the articles are built upon, though the latter have greater impacts. As a partial contribution to the field of second language writing, a practical taxonomy is also proposed to account for the contextualized citation functions in the two disciplines. The study concludes with some pedagogical implications
