RESUMO

This dissertation comprises a study in descriptive linguistics. The aim is to elaborate criteria for the segmentation of Brazilian Sign Language (Libras) discourse into grammatical units. Two theoretical fields contributed crucially to this project: conversation analysis and usage-based grammar. Conversation analysis, by focusing observation on how participants themselves orient to each other in interaction, has revealed a perspective on grammatical resources as social practices designed for the deployment and coordination of social actions in conversation. Usage-based grammar, by exploring the relations among language, cognition and interaction, reveals the important role of prosody and gesture for the establishment of joint attention in interaction. In the construction of the corpus, dyads composed of fluent adult speakers of Libras were recorded in a studio, with lights and cameras positioned in order to capture both the face and the signing space of each of the speakers, in addition to the two speakers in profile. An excerpt from one of the conversations was selected to be transcribed and used as the main point of reference for the analysis, which involved two distinct phases. In the first phase, it is demonstrated that the principle of one-at-a-time, a manifestation of joint attention at the level of discourse, also holds in a language of gestural-visual modality like Libras. In the second phase, the internal segmentation of turns at talk is analyzed, by combining an approach focused on the minimal prosodic units of discourse with an approach focused on structured practices of discourse, such as lists and contrasts. The major contributions resulting from the analysis are: i) a systematized repertoire of manual and non-manual resources of Libras which can serve as an initial point of reference for the segmentation of signed discourse into grammatical units; and, ii) an approach to the identification of prosodic units which, in future investigations, may permit further advancements with respect to our understanding of the prosodic resources of Libras.
