This dissertation examines the strategic deployment of evidential resources in communicative interactions among Nantis, an Arawak people of Peruvian Amazonia. In particular, this work focuses on Nantis' uses of evidentials to modulate representations of responsibility, and shows that two distinct types of responsibility must be distinguished in order to account for the socially instrumental properties of evidential resources: event responsibility and utterance responsibility. Event responsibility concerns praiseworthiness or blameworthiness for happenings in which the relevant individual is causally implicated; while utterance responsibility concerns the socially salient attributes of an utterance (e.g. truthfulness), and not the utterance's consequences. Evidential resources are shown to mitigate event responsibility in Nanti interactions by serving as a pragmatic metaphor, whereby the sensory directness or indirectness encoded by evidentials yields inferences regarding individuals' participation in, and responsibility for, events. The use of evidential resources, principally quotative resources, to modulate utterance responsibility operates on quite different principles. Specifically, quotative resources serve to individuate utterances by attributing them to a particular source, thereby rendering explicit that individual's commitment to the stances expressed by the quoted utterance. In doing so, the use of the quotative resource emphasizes that individual's responsibility for the expressed stance. Quotative resources are also employed to decrease a first party's responsibility for a stance, by attributing it to a third party. In this case, inferences based on the Maxim of Quantity lead interactants to infer reduced commitment on the part of the first party on the basis of the attribution of strong commitment to a third party. Both epistemic stance and a variety of moral and evaluative stances are relevant to utterance responsibility. Significantly, utterance responsibility is one of the few areas in which a pragmatic tie exists between evidentiality and epistemic modality, indicating the relative marginality of epistemic modality to evidentiality in Nanti, even at the level of pragmatics. An ethnographic and historical sketch of the Nanti people is provided, and a grammatical description of the Nanti language is also included. / text

This dissertation explores the phenomenon of ways of speaking in the Nanti speech community of Montetoni, in southeastern Peruvian Amazonia, between 1999 and 2009. In the context of this study, a 'way of speaking' is a socially meaningful, conventionalized sound pattern, manifest at the level of the utterance, that expresses the speaker's orientation toward some aspect of the interaction. This study closely examines both the sound patterns and patterns of use of three Nanti ways of speaking — matter-of-fact talk, scolding talk, and hunting talk — and describes each one in relation to a broader set of linguistic, social, and cultural practices characteristic of the speech community at the time. The data for this study is naturally-occurring discourse recorded during multi-party, face-to-face interactions in Montetoni. Bringing together methods developed by linguists, linguistic anthropologists, conversation analysts, and interactional sociologists, this study explores the communicative relations among participants, interactions, situations of interaction, and the utterances that link them all, attending to both the individual-level cognitive (subjective) facets of interpersonal communication and the necessarily intersubjective environment in which communication takes place. In order to disaggregate the multiple levels of signification evidenced in specific utterances, tokens are examined at four levels of organization: the sound form, the sentence, the turn, and the move. The data are presented via audio files; acoustic analyses; sequentially-organized and temporally-anchored interlinearized transcripts; and composite visual representations, all of which are framed by detailed ethnographic description. Nantis' ways of speaking are shown to consistently and systematically convey social aspects of 'meaning' that are crucial to utterance interpretation and, therefore, to successful interpersonal communication. Based on the robust correspondences between sound form and communicative function identified in the Nanti communicative system, this study proposes that ways of speaking are a cross-linguistically viable level of organization in language use that awaits discovery and description in other speech communities. The research project itself is framed in terms of the practical issues that emerged through the author's own experiences in learning to communicate appropriately in monolingual Nanti society, and the ethical issues that motivate community-oriented documentation of endangered language practices. / text
