Abstract:

Modality is one important part of the interpersonal meta-function, which is particularly essential in political discourse. Based on Halliday's Systemic Functional Grammar, this paper tries to analyze the interpersonal meanings of the values of modal operators of 30 English political interviews in order to see how interpersonal meanings are revealed through the usage of different values of modal operators. Results indicate that both sides tend to use similar and different amounts of modal operators with different values. The use of different values of modal operators by the interviewers and the interviewees is influenced by both social roles and roles in the interaction. Usages of different values of modal operators not only show the power relationships, but also show the interaction of the participants. This study hopes to provide a new perspective for understanding political discourse.
