Book excerpt: Recent years saw a growing interest in the study of subjectivity, as the linguistic expression of speaker involvement. Intersubjectivity, defined by Traugott as "the linguistic expression of a speaker/writer's attention to the hearer/reader", on the other hand, has so far received little explicit attention in its own right, let alone systematic definition and operationalization. Intersubjectivity and seemingly related notions such as interpersonal meaning, appraisal, stance and metadiscourse, frequently appear in cognitive-functional accounts, as well as historical and more applied approaches. These domains offer (partly) conflicting uses of 'intersubjectivity', differ in the overall scope of the concept and the phenomena it may cover.This book brings together contributions from a variety of different approaches, with the aim of disentangling the current web of intertwined notions of intersubjectivity. Rather than focusing on the potentially conflicting views, the volume aspires to resolve some of the conceptual puzzle by cross-fertilization between the different views, and spark discussion on how to operationalize 'intersubjectivity' in linguistic research.
