A comparison of verbal person marking across Tupian languages Uma comparação da marcação verbal de pessoa nas línguas Tupí

this paper explores the diachrony of the verbal person marking system across the large and structurally diverse tupian language family. i argue that the historical development of these different patterns are best informed by analyzing their synchronic distributions with regard to the current evolutionary hypotheses on the family. i apply a parsimony reconstruction model across the topology of two different classifications and compare the results with what is known from traditional historical linguistic work. this study is able to provide support for previous claims about the family and also generates a number of additional hypotheses about the intermediate stages of development of these patterns.
