Pesquisa em Foco, São Luís, v. 16, n. 1, p. 47-57, 2008.http://repositorio.bc.ufg.br/handle/ri/19837The role carried out by Reflexões de aspectos morfofonêmicos das vogais do português in the structuralistc studies context. It is the aims this work. We claim based on indicated authors in the text, that there is a strict relationship between the phonological rules and the morphological rules in what concerns the empirical problems analyzed by two lines of studies, so we emphasize the importance of the vowel’s role like intersection point in the treatment of the morpho-phonics data. The paper has support on Câmara Jr. theoretical presuppositions (1977, 1998, 2001, 2005).porAcesso AbertoProcessos morfofonêmicosVogaisPortuguêsMorphophonemic processesVvowelPortugueseArtigo10.18817/pef.v16i1.11
