In this paper we bring together data from several varieties of Catalan and Spanish with the purpose of investigating the behavior of glides (i.e., /j/ and /w/) in onsets and codas, and the way they adjust to the syllable margins. We cast our analysis within Optimality Theory and, more specifically, we provide support for the distinction proposed by Baertsch (2002) between elements which are parsed as the leftmost element in the onset (M1: Margin 1) and elements which are syllabified as codas or as the second element in the onset (M2: Margin 2). The data indicate, though, that sometimes an explicit reference to the intersyllabic context in which M1 elements appear is also required.... [Llegir més ...]
