Coahuiltecan

Coahuiltecan was a language family proposed in John Wesley Powell's 1891 classification of Native American languages, grouping together the poorly documented languages of southern Texas and adjacent northern Mexico, including Coahuilteco (also called Pakawa), Comecrudo, Cotoname, Aranama, Solano, Mamulique and Garza. Most modern linguists reject the idea that these languages were actually related, and now treat them as a set of unrelated isolates or, in the case of Comecrudo, Cotoname and Garza, as members of a separate small Comecrudan family; the original Coahuiltecan proposal rested on cultural similarity among the peoples rather than demonstrated linguistic relationship. The languages were already dying out by the late 19th century, with only 28 known speakers recorded across the group in 1886, and none survive today.
