As soantes palatais do português na diacronia e na aquisição da linguagem escrita

Abstract

The Portuguese palatal sounds, nasal and liquid, were introduced into the system from processes that occurred during the evolution from Latin to Portuguese, which according to Silva (2001), are due to the phenomenon of palatalization. According to Matzenauer-Hernadorena (1994), from the melodic point of view, that is, in segmental terms, the palatal sound has a complex structure because present in their geometry two articulations, a primary at the consonant point and a secondary at the vocalic node. Considering the complexity of these two consonants, this dissertation aims to investigate the behavior of palatal sound, considering diachrony and writing acquisition. For this are approached the processes involved in the evolution of the Latin to Portuguese of these two sounds, considering the phonological aspects involved, as well as the studies on the acquisition of phonology, in order to reflect on the process of acquisition of written language. For the composition of the corpus of the research, written data of Brazilian and Portuguese children belonging to strata 3 and 4 of BATALE - Banco de Textos de Aquisição da Linguagem Escrita were analyzed. The sample used for the analysis of the processes involved in the diacrony of the palatal sound was composed by data extracted from books that deal with the historical evolution from Latin to Portuguese. The results demonstrated that the processes verified in the diachrony and the acquisition occur in opposite directions. It is possible to observe in the data that there is a simplification of the consonants complex by the children in the acquisition of writing while the inverse process occurs in the diacrony of the palatal sound.
