Epistemic modality in English-medium medical research articles: A systemic functional perspective

Abstract Epistemic modality is a critical yet intricate linguistic device in academic writing. In this study, we investigated the use of epistemic modality in 25 English-medium medical research articles (RAs) from a systemic functional perspective. We focused on the distribution of the value and the orientation of epistemic modality and their functions in medical RAs. The results showed that medical RA writers mostly rely on low and median values, and implicitly subjective, implicitly objective and explicitly objective orientations of epistemic modality. These findings indicate that medical RA writers tend to make claims mainly in a tentative, reserved and objective way. The findings of the study may help non-native medical RA writers to produce more acceptable medical RAs.
