This chapter will sketch some current findings, questions, and trends in approaches to the study of language variation and identity. The term "identity" functions outside of linguistics to cover a variety of concepts; for our purposes, we will understand identity to mean the active negotiation of an individual's relationship with larger social constructs, in so far as this negotiation is signaled through language and other semiotic means. Identity, then, is neither attribute nor possession, but an individual and collective-level process of semiosis. We shall be concerned with its emblematic sites, its codes and its channels (Silverstein 1998), and, crucially for variation theory, with its richly patterned, multivariate nature. The scope of this particular review will be limited to works that are broadly representative of or that stand in dialogue with the Labovian quantitative sociolinguistic tradition, and will of necessity exclude significant qualitative research on linguistic identity that falls under the rubric of sociology of language and discourse analysis. (For a review of the literature within this field, see Tabouret-Keller 1998.) Though much-debated in identity theory, psychological processes internal to the individual, such as (Freudian prelinguistic) identification, sublimation, fantasy and desire, and their role in identity formation (Zizek 1993, Salecl 1994, Lacan 1977 are, to say the least, difficult to study under the standard empiricist lens of variationist inquiry unless they are overtly signaled in interaction (but see Kulick 2000 for an exhortation to undertake exactly such studies in the area of language and sexuality).Although this review will incorporate selected developments in anthropology, psychology, social theory, and literary theory, for more in-depth analysis in these areas I refer the reader to other works dealing with field-specific perspectives on identity and identity politics (
