Possessive inflection in Proto-Zamucoan: a reconstruction

This paper presents a comparative analysis of possessive inflection in the three known Zamucoan languages: Ayoreo and Chamacoco – still spoken in the Chaco area between Bolivia and Paraguay – plus †Old Zamuco, described by the Jesuit father Ignace Chomé in the first half of the 18th century. The comparison allows us to build a plausible reconstruction of Proto-Zamucoan possessive inflection. Old Zamuco appears to be the most conservative language among the three, while Chamacoco appears to be the most innovative, although it exhibits relics of special importance for reconstructive purposes. Our analysis identifies in Zamucoan a series of features of general interest for the typology of person marking.
