Providing an up-to-date, multi-perspective and cross-linguistic account of the centrality of the expressive function in communication, this book explores the conceptualization of emotions in language and the high emotional 'temperature' of a variety of contemporary discourses. Adopting a number of methodological angles, both qualitative and quantitative, the chapters present insights from cognitive linguistics, (critical) discourse analysis, corpus linguistics and sociolinguistics, as well as those resulting from the combination of these approaches. Using a wide variety of data types, from song lyrics and TV series to Twitter posts and political speeches, and through the analysis of a range of languages, including Arabic, English, Polish, Italian, Hungarian, and Turkish, the book offers a panoramic view of the multi-faceted interaction between language, expressivity and cognition.
