How does the Macro-Mayan hypothesis classify Totonacan languages?

The Macro-Mayan hypothesis is a proposal that attempts to group the Mayan, Mixe-Zoquean, Totonacan, and Huave language families into a single, broader genealogical unit.12

Within this framework, Totonacan languages—which consist of the Totonac and Tepehua branches—are classified as a potential member of this larger grouping. However, it is important to note that the Macro-Mayan hypothesis is not a confirmed classification; it is widely considered to be an essentially rejected or inconclusive proposal due to a lack of sufficient supporting evidence. Scholars have noted that the methods used to support such hypotheses often fail to distinguish between genuine inherited linguistic material and other factors, such as loanwords or accidental similarities.12
