Brazilian Sign Language, also known as "Libras" (Portuguese pronunciation: [ˈlibɾɐs], from "Língua Brasileira de Sinais" [ˈlĩɡwɐ bɾɐziˈlejɾɐ dʒi siˈnajs]) and previously known as LSB, LGB or LSCB (Brazilian Cities Sign Language), is the sign language used by deaf communities of urban Brazil, or the area concentrating 85–90% of its population.
Recognition and status
Libras is well-established; several dictionaries, instructional videos and a number of articles on the linguistic features of the language have been published. It has dialects across Brazil reflecting regional and sociocultural differences.
A strong sign language law was passed by the National Congress of Brazil on April 24, 2002, and (in 2005) is in the process of being implemented. The law mandates the use of Libras in education and government services.
Deaf and sign language organizations
The most important deaf organization is FENEIS, the Federação Nacional de Educação e Integração dos Surdos (National Federation of Deaf Education and Integration). There are a number of regional organizations in Curitiba, Caxias do Sul and Rio Grande do Sul.
Wittmann (1991) posits that LIBRAS is a language isolate (a 'prototype' sign language), though one developed through stimulus diffusion from an existing sign language, likely Portuguese Sign Language and/or French Sign Language.
Nevertheless, autochthonous sign languages flourished among Brazil's Indigenous peoples (that perhaps influenced Libras to some degree), and it shows similarities with members of the French Sign Language family.
