[5] Coahuilteco or Pakawa seems to have been a lingua franca of Texas Coahuiltecans living at or near the Catholic Missions established at San Antonio in the 18th century.

In 1886, ethnologist Albert Gatschet found perhaps the last surviving speakers of Coahuiltecan languages : 25 Comecrudo, 1 Cotoname, and 2 Pakawa.

The Coahuiltecans were sold into slavery, died of introduced European diseases, and were absorbed by the surrounding Hispanic population.

The names of many bands have been preserved, including the Ervipiame, Mayeye, Pajalat, Quems, Quepano, Solano, and Xarames.
