EPENTHESIS GOES BEYOND PHONOLOGY: A UNIFIED FORMAL ACCOUNT

The main descriptive and analytical goal of this article is to unify under the umbrella of epenthesis - the insertion of meaningless phonological material - a number of lexically and morphosyntactically conditioned phenomena that have been treated disparately in past research. Many previous analyses of what we call ªnon-canonical epenthesisºhave resorted to extra devices such as listed allomorphs and abstract segments. We reanalyze the data as instances of epenthesis with morphosyntactic and lexical conditioning, without resorting to such devices. Throughout, we separate the phonological fact of epenthesis from the lexical and morphosyntactic conditions that determine precisely what segment is epenthesized. Finally, we model the interactions between variously conditioned forms of epenthesis using Boolean Monadic Recursive Schemes (Bhaskar et al. 2020; Chandlee & Jardine 2021).
