Linguistic polyphony is an utterance act theory (la linguistique de l'énonciation) and is a French specialty. It deals with the numerous points of view that are likely to be communicated through an utterance. The book introduces utterance act theory and polyphony as such, but most especially focuses on the Scandinavian variant of polyphony, ScaPoLine. ScaPoLine is a formal linguistic theory whose main purpose is to specify the instructions conveyed through linguistic form for the creation of polyphonic meaning. The theoretical introduction is followed by polyphonic analyses of linguistic phenomena such as negation, mood, modality and connectors, and of textual phenomena such as represented discourse and irony. The book suggests how ScaPoLine could offer new insights within cross-linguistic and interdisciplinary studies.
