A perennial conflict in historical linguistics centers around the theoretical and practical virtues of tree-like
divergence and wave-like diffusion. This paper presents the Dialect Chain Tree, an extension of the tree model that incorporates
both tree-like descent and disintegration of dialect chains in a systematic fashion. As such, it provides a formalization and
sharpening of Ross’ (. 1997. Social
networks and kinds of speech community event. In Roger M. Blench & Matthew Spriggs (eds.), Archaeology
and language, I, vol. 271 (One World
Archaeology), 209–261. London & New York: Routledge.: 212–228) linkage concept that allows integration into
quantitative approaches.
Keywords: phylogenetics, subgrouping, dialect chain, trees and waves
Résumé
Un conflit éternel en linguistique historique tourne autour des avantages théoriques et pratiques du modèle
arborescent et de la théorie des vagues. Cet article présente le Dialect Chain Tree (arbre avec chaînes dialectales), une
extension du modèle arborescent qui intègre de manière systématique la descendance en forme d’arbre et la désintégration des
chaînes dialectales. Il fournit ainsi une formalisation et un raffinement du concept de linkage (lien) de Ross (. 1997. Social
networks and kinds of speech community event. In Roger M. Blench & Matthew Spriggs (eds.), Archaeology
and language, I, vol. 271 (One World
Archaeology), 209–261. London & New York: Routledge.: 212–228) qui permet l’intégration des ruptures dialectales dans des analyses
quantitatives.
Zusammenfassung
Ein regelmäßig wiederkehrender Konflikt in der historischen Linguistik dreht sich um die theoretischen und
praktischen Vorteile der Stammbaumtheorie gegenüber der Wellentheorie. In diesem Artikel wird der Dialect Chain Tree vorgestellt,
eine Erweiterung des Stammbaummodells, der auf systematische Weise sowohl stammbaumähnliche Weitergabe als auch Disintegration
von Dialektketten berücksichtigt. Er bietet somit eine Formalisierung und Präzisierung des (Verknüpfung-)Konzeptes von Ross (. 1997. Social
networks and kinds of speech community event. In Roger M. Blench & Matthew Spriggs (eds.), Archaeology
and language, I, vol. 271 (One World
Archaeology), 209–261. London & New York: Routledge.: 212–228), was eine Integration in quantitative Ansätze ermöglicht.
