Expressões não-manuais lexicais em Libras

Abstract

Resumo: As línguas de sinais se manifestam tanto através de movimentos das mãos/braços – expressões manuais – quanto através de movimentos da cabeça, da face e do torso – expressões não manuais (ENM). Liddell, na década de 1970, foi o primeiro a perceber o papel das expressões não manuais na gramática da língua de sinais americana, especificamente na sua sintaxe (LIDDELL, 2003). Posteriormente, Brennan (1992) atestou sua ocorrência na formação de sinais da língua de sinais britânica e, assim, demonstrou a existência de ENM lexicais. Este trabalho se baseia em Xavier (2019), que investigou expressões não-manuais associadas a 368 sinais da libras dicionarizados por Capovilla e Rafael (2001). Seu objetivo é comparar os resultados obtidos por Xavier em relação a quantos e quais articulatores são envolvidos na produção dessas ENM, bem como ao caráter estável (sem mudança) ou dinâmico (com mudança) destas com os obtidos através da análise dos mesmos sinais documentados em vídeo no dicionário on-line "Acessibilidade Brasil". Os resultados, baseados em 234 sinais, reforçam os de Xavier (2019), pois se observou que a realização desses sinais envolvem ENM predominantemente produzidas por mais de um articulador, articuladas pela boca e estáveis. Com esses resultados, espera-se contribuir com um melhor entendimento das ENM lexicais na libras.

Liddell, in the 1970s, was the first to realize the role of nonmanual expressions in American Sign Language grammar, specifically in its syntax (LIDDELL, 2003). Subsequently, Brennan (1992) attested its occurrence in the formation of signs of British Sign Language and thus demonstrated the existence of lexical NMs. This work is based on Xavier (2019), who investigated nonmanual expressions associated with 368 Libras signs from Capovilla and Rafael’s (2001) dictionary. Its objective is to compare the results obtained by Xavier in relation to how many and what articulators are involved in the production of these NMs, as well as their stable (without change) or dynamic (with change) character with those obtained through the analysis of the same signs documented in video in the online dictionary "Accessibilidade Brasil". The results, based on 234 signs, reinforce those of Xavier (2019), since it was observed that the realization of these signs involves predominantly ENM produced by more than one articulator, articulated by the mouth and stable. With these results, it is expected to contribute to a better understanding of lexical Libras NMs.
