"The volume aims to advance understanding of argumentative practices in different communicative contexts, with special regard for those with heightened public resonance: politics, media, and public debate in general. Furthermore, it intends to explore the linguistic aspects of argumentation, including both explicit codification, with the related issue of indicators, and the activation of implicit meanings. Bringing together different paradigms to account for the relations between contextual factors and discourse realizations, the contributions articulate around three foci, placing emphasis on one or more of them: the communicative purpose within a given genre or activity type; the argumentative and linguistic features of the investigated discourses, among which prototypical patterns, argumentative styles, and implicit meanings; the assessment of argumentation quality and strategies to cope with illegitimate practices"--.
