Linguistic taboo has been relegated for a long time to a peripheral position within Linguistics, due to its social stigmatization and inherent linguistic complexity. Recently, though, there has been a renewed interest in revisiting the phenomenon, especially from cognitive frameworks. This volume is the first collection of papers dealing with linguistic taboo from that perspective. The volume gathers 15 chapters, which provide novel insights into a broad range of taboo phenomena (euphemism, dysphemism, swearing, political correctness, coprolalia, etc.) from the fields of sexuality, diseases, death, war, ageing or religion. With a special focus on lexical semantics, the authors in the volume work within Cognitive Linguistics frameworks such as conceptual metaphor and metonymy, cultural conceptualization or cognitive sociolinguistics, but also at the interface of pragmatics, discourse analysis, applied linguistics, cognitive science or psychiatry. This volume provides theoretical reflections and case studies based on new methods and data from varied languages (English, Spanish, Polish, Dutch, Persian, Gikũyũ and Egyptian Arabic). As such, it moves towards a new generation of linguistic taboo studies.
