In this study, the author describes the linguistic expression of space in Caac, an endangered and under-documented Oceanic language spoken in New Caledonia, from both a descriptive and theoretical perspective. Part I provides a concise description of Caac grammar, presenting a first formal portrait of this language to the reader. Part II describes the formal and semantic features of the linguistic resources available in Caac to encode spatial relationships. Part III presents the theoretical framework based on and exploring further the vector analysis developed by Bohnemeyer (2012) and Bohnemeyer & O'Meara (2012).
In particular, the author proposes an additional sub-category of vectors (Head-unspecified Vectors) which accounts for the uses of centrifugal forms in Caac. The resulting framework provides a systematic account of expressions of orientation as well as location and motion, and to combine the Frames of Reference typology (Pederson et al. 1998; Levinson, 1996, 2003; Bohnemeyer & Levinson, not dated) with an analysis of deictic expressions within a single framework. Special attention, moreover, is given to the use of Caac absolute and deictic directionals in spatial constructions involving Fictive Motion. The analysis of Caac data leads us to introduce an additional category of Fictive Motion beyond those previously recognised in the literature, labelled here "Anticipated Paths", which in turn shed new light on the nature of vectors and the relationship between location, motion and orientation.
