Welsh svarabhakti as stem allomorphy

This paper develops the analysis in this presentation. I offer an analysis of Welsh epenthesis, whereby a copy of a preceding vowel is inserted to break up final clusters of rising sonority (pwdr ‘rotten’ is [pudur] rather than *[pudr]) and deletion in such clusters in polysyllables (perygl ‘danger’ is [perɪɡ] rather than *[perɪɡl]). It has previously been argued that both processes can be analysed in a single phonological grammar. I show that this is not tenable for South Welsh dialects, and propose an analysis in terms of part-of-speech-specific allomorphy, formalized as lexical storage of POS-characterized stems rather than roots.
