This chapter explores how emotions are expressed, named, and strategically deployed in argumentative discourse. Drawing on discourse analysis, rhetorical theory, and Pragma-Dialectics, it examines the functions of emotion terms, the role of emotional appeals in dialogical action, and the interaction between metaphor and affect. The chapter begins by tracing the French tradition of analyzing emotion naming as a marker of speaker involvement, commitment, and evaluative stance. Then it turns to dialogical perspectives, showing how emotions function as both argumentative resources and potential sources of fallacy. A review of rhetorical and computational approaches illustrates how emotions are increasingly recognized as integral to argument quality, audience adaptation, and persuasion. Finally, the chapter analyzes the role of metaphor as a conceptual and affective device in argumentation. An empirical study of political discourse demonstrates that metaphor and emotional appeal frequently co-occur, suggesting that speakers select emotionally resonant source domains to strengthen the persuasive force of arguments.
