Teoria fonológica e variação linguística aplicadas a libras.

Abstract

This paper develops a literature review based on two axes: structuralist principles and linguistic variation, applied in sign language. In Saussurean theory, stand out four pairs of central concepts, they are: "synchrony and diachrony", "language and speech", "signifier and signified" and "paradigm and syntagm." These dichotomies can be related to the linguistic studies of sign language. The objective is to analyze three categories of the phonology of sign language: handshape, location and movement, seeking thus to investigate the distinctive features of the categories. Therefore, notice the occurrence of changes in minimum units that can generate lexical items with the same meanings, and the relationship with the term phonological variant or allophone.
