Data dubbed "peripheral" or previously unaccounted for have inspired new methods, new models and theories of language and new ways of understanding language and communication within pragmatics. The chapters in the volume extend this perspective to include language users and their identities as central, taking into account the ideologies that mediate their perception of language use. Identities and peripheries are approached geographically (Europe, North America, Africa, Asia; dialectal variation), socially (gender, age, social status), medially (traditional, electronic and multimedia), occupationally (trade, congregation) and from the points of view of healthcare and of professional relations. The volume includes the editors' introductory overview of challenges in the field, and chapters divided into three parts, Building the Peripheral Stage; Identities in Interaction; and Gender, Narratives, and Peripheries. By particularizing a variety of linguistic peripheries, the volume fosters a deeper understanding of human interaction.
