A relação sintatico-semântica dos verbos e seus argumentos na língua brasileira de sinais (Libras)

Abstract

Study about Brazilian Sign Language (LIBRAS) verbs and the main objective is to do a classification of them through their morpho-syntactic-semantic components. For doing this study, it was necessary to rethink about language typologies, grammatical categories and to do a field researching. The verb was presented as a lexical item that has a root where aggregate other elements: the agreement marks and satellites. So the verb is a net and its arguments must be submitted to rules that select the theta roles and the diathesis altemations. There is a verbal frame that induces to a theta frame that induces to a phrasal frame. The Brazilian sign language verbs were divided into classes in order to their agreement system: gender, discourse person/number and locative. The research results give a contribution to general language theory because they demonstrate the application of the same principles used to oral languages.
