Effects of phonological phrasing on syntactic structure

Bantu languages are renowned as tone languages that utilize this suprasegmental feature not only on the lexical level to distinguish lexical items, but also on the grammatical level to distinguish clause types. This article investigates one such use of grammatical tone in relative clauses in Bemba where a low tone can be used in place of a segmental relative marker. This low tone relative morpheme functions in conjunction with phrase boundary tone indicated on the head noun and which entails either restrictive or non-restrictive interpretations of relatives. Considering a mapping of XPs to major phonological phrases in the syntax-prosody interface, the resultant phonological phrasing in relatives influences the choice of syntactic structure. In the case at hand, a head-raising analysis provides an optimal mapping between syntax and prosody for restrictives. Further, a more direct influence of phonology on syntax can be seen in a perception-based model like Dynamic Syntax where the on-line building of syntactic trees can gain import from phonological information. © Walter de Gruyter 2007.
