The article proposes a framework for the analysis of identity as produced in linguistic interaction, based on the following principles: identity is the product rather than the source of linguistic and other semiotic practices and therefore is a social and cultural rather than primarily internal psychological phenomenon; identities encompass macro-level demographic categories, temporary and interactionally specific stances and participant roles, and local, ethnographically emergent cultural positions; identities may be linguistically indexed through labels, implicatures, stances, styles, or linguistic structures and systems; (...) identities are relationally constructed through several, often overlapping, aspects of the relationship between self and other, including similarity/difference, genuineness/artifice and authority/ delegitimacy; and identity may be in part intentional, in part habitual and less than fully conscious, in part an outcome of interactional negotiation, in part a construct of others’ perceptions and representations, and in part an outcome of larger ideological processes and structures. The principles are illustrated through examination of a variety of linguistic interactions. (shrink)
