This talk brings semiotics and linguistic anthropology into dialogue in order to propose a new line of research: a semiotics of social identities.In the linguistic anthropology proposed by Michael Silverstein and developed by Constantine Nakassis, the concept of index has been reinterpreted in an original way, in accordance with a general metapragmatic function of language. It is not a matter of studying particular indexical signs that refer to things, but of considering the way in which any enunciation — through utterance contents and speech registers, for instance — contributes to the construction of its contextual parameters in an indexical manner. Indexicality becomes the fundamental dimension through which it is possible to study the relationship between enunciation and socio-semiotic variables.Semiotics, on the other hand, has traditionally conceived of subjects as actants, bodily entities or enunciative instances acting through practices. Although the questions of the body and of forms of life have been addressed — for instance in of Jacques Fontanille’s work — the study of identities has remained implicit or treated as unrelated to the study of signifying forms. However, a number of social phenomena remain outside this conception. For example, Johnny Depp’s identity is made up of his bodily performances, which give rise to fictional characters (J. Sparrow, W. Wonka), trans-domanial enunciations (press articles, advertisements), and social practices (the trial against Amber Heard). My working hypothesis is that these enunciative and axiological positions are held together by an encompassing and dynamic identity built in an indexical manner.
