Phase domains at PF
This chapter investigates some implications of Spell-Out in a phase-based, realizational derivational system. It is argued that all operations on the PF branch within a phase, specifically Vocabulary Insertion and phonological rule, application are predicted to have isomorphic domains of application. This has implications for the proposals on how to extend suppletion domains found in Embick (2010) and Bobaljik & Wurmbrand (2013). Apparent mismatches in suppletive vs. phonological domains are examined in a number of languages, including English, Yiddish, Turkish, Ojibwe, Malagasy, and German. The data are argued to support modifications to both (i) certain theoretical proposals held in the literature, and (ii) the syntactic location of triggers for suppletion generally assumed.
