Coahuitlán Totonac is spoken in Veracruz, Mexico, and has been variously ascribed to two different branches of the Totonacan family tree. While recent work has begun to bring empirical evidence to the internal structure of this family tree, there remain several important areas of disagreement, in addition to the disputed affiliation of Coahuitlán. This article informs the family tree and demonstrates that Coahuitlán belongs to the Northern branch using shared innovations and two computational methods. The comparative method seeks sets of shared innovations for evidence of subgrouping. This article presents proposed shared innovations in phonology, morphology, and lexicon, which fall into two sets, one belonging to the Sierra and Lowland branches, and the other belonging to the Northern. Coahuitlán Totonac overwhelmingly shares innovations found in Northern languages and lacks innovations found in Sierra. Two quantitative methods are also used to show that Coahuitlán groups groups closely with other Northern languages.
Coahuitlán Totonac est parlé à Veracruz au Mexique et s'est vu assigné à deux branches différentes de l'arbre familial Totonacan. Malgré les travaux récents qui portent de nouveaux faits empiriques concernant la structure interne de cet arbre familial, plusieurs sujets inspirent encore la controverse. À l'aide d'innovations communes et de deux méthodes computationnelles, cet article éclaircit l'arbre familial et montre que Coahuitlán appartient à la branche du nord. La méthode comparative cherche des innovations communes pour établir des sous-groupes. Cet article présente des innovations communes aux niveaux phonologiques, morphologiques, et lexiques qui se divisent en deux groupes, l'un appartenant aux branches Sierra et Lowland, l'autre appartenant à la branche du nord. Coahuitlán Totonac présente surtout ces innovations caractéristiques des langues du nord et manque des innovations attestées en Sierra. Deux méthodes quantitatives sont également employées afin de montrer que le groupe Coahuitlán est similaire aux autres langues du nord.
