We describe a statistical model over linguis- tic areas and phylogeny. Our model recov- ers known areas and identifies a plausible hi- erarchy of areal features. The use of areas improves genetic reconstruction of languages both qualitatively and quantitatively according to a variety of metrics. We model linguistic areas by a Pitman-Yor process and linguistic phylogeny by Kingman’s coalescent.
