%0 Journal Article %T Central, epenthetic, unmarked vowels and schwas : a brief outline of some essential differences %A Jo£¿o Veloso %J Lingu¨ªstica : Revista de Estudos Lingu¨ªsticos da Universidade do Porto %D 2010 %I Universidade do Porto %X In this study, we examine the nature and content of some phonetic/phonological designations to refer to central vowels. Bearing in mind that epenthetic vowels and unmarked vowels are not always central vowels, we will argue in favour of a thorough distinction between these designations and propose the use of: 1. ¡®Central vowels¡¯ to label vowels articulated along the central axis the of oral cavity, 2. ¡®epenthetic vowels¡¯ to refer to postlexically inserted vowels in order to regularize exceptional consonant strings, 3. ¡®unmarked vowels¡¯ to indicate the most frequent epenthetic vowels of a language. Additionally, the term ¡®schwa¡¯ is judged not strictly necessary to phonetic and phonological description, since it does not clearly separate the different meanings associated with more transparent designations such as ¡®central¡¯ or ¡®epenthetic vowels¡¯ %K Central vowels %K epenthetic vowels %K epenthesis %K unmarked vowels %K schwa %U http://ler.letras.up.pt/uploads/ficheiros/8982.pdf
