This volume deals with the interplay between personal identity and language, with a special focus on interactions involving political correctness, ideological positioning and minority groups. Differently from many studies adopting only either an abstract observational perspective or a militant one, this volume aims at describing identity construction as an interactional practice, in order to offer a comprehensive and varied picture of how communicative practices may either facilitate or hinder effective interaction. Processes of community building, (collective) identity construction, and ingroup/outgroup strategies are discussed by scholars of different disciplines (philosophy of language, linguistics and sociology) through the analysis of both linguistic and multimodal resources in online and offline interactions.
