Pre-contact distribution of Comecrudan languages. (Distribution continues to the south.)
Comecrudan refers to a group of possibly related languages spoken in the southernmost part of Texas and in northern Mexico along the Rio Grande of which Comecrudo is the best known. Very little is known about these languages or the people who spoke them. Knowledge of them primarily consists of word lists collected by Europeanmissionaries and explorers. All Comecrudan languages are extinct.
Edward Sapir (1920) accepted Swanton's proposal and grouped this hypothetical Coahuiltecan into his Hokan stock.
After these proposals, documentation of the Garza and Mamulique languages was brought to light, and Goddard (1979) believes that there is sufficient similarity between them and Comecrudan for them to be considered genetically related. He rejects all other relationships.
Powell's original Coahuiltecan, renamed Pakawan and extended with Garza and Mamulique, has been defended by Manaster Ramer (1996), who also sees a relationship with Karankawa probable and Atakapa as a more distant possibility.
The following table of common core vocabulary constitutes the complete evidence given by Goddard (1979) in support of a Comecrudan family:
