Contemporary linguistics and semiotics treat the term indexicality in a variety of ways. Broadly speaking, indexicality can refer to: (a) context-sensitive aspects of sign systems (in the case of natural languages, things like “shifters” and “deictics”), (b) traces of the emitter’s identity included in the message being produced (in the case of natural languages, things like pronunciations associated with a specific geographical or social provenance), and (c) a specific type of meaning making process whereby one thing points to another either by “contiguity”, “causality”, or other type of determination excluding resemblance or pure convention. The problem supposed by indexicality (and to some extent by any other type of sign) is whether indexicality is to be defined by properties of the sign involved in a process of interpretation or by the role of the subject producing or interpreting the given sign. While Peircean semiotics aims to establish a comprehensive typology of signs that excludes proper subjects from it, and thus focuses on the underlying “logic” of interpretation, a type of Saussurean semiology that grew out of the functionalist interpretation of Saussure (i.e. Martinet, Mounin, Prieto, etc.) put forward (albeit implicitly and not explicitly) a typology of signs that rests upon the assumption of a community of interpreters wherein social subjects that carry out interpretation processes constitute the basis of such typology. This presentation will introduce such typology and will present the impact it has for defining the notion of sign itself, and thus the object of study of a general semiotics.
