This paper provides a preliminary phonological analysis of prosodic phrasing in Breton (brezhoneg), an endangered Celtic language spoken in Brittany, France. Unlike other Celtic languages, which show a predominantly VSO word order, Breton has a canonical verb-second (V2) word order but also allows verb-initial word order in certain contexts. In this study, we investigate prosodic phrasing in declarative sentences with a variety of verb-initial and verb-second word orders. In addition, we systematically vary the length of the subject and object (noun vs. noun-adjective), in order to account for possible effects of binarity on prosodic phrasing. In this preliminary report, we describe the patterns of prosodic phrasing and the distribution of an LH* pitch accent for two native speakers of Breton, HG and JS, and consider the relationship between syntactic structure and prosodic phrasing.
