Sabine River Spanish is a variety of the Spanish language spoken on both sides of the Sabine River between Texas and Louisiana. It has been spoken by a few communities descended from the 18th-century colonists who established Los Adaes and Nacogdoches. Due to its historical origins, it has a mostly conservative phonology with a vocabulary derived from rural Mexican Spanish. It is facing language death as it has not been passed onto children for several generations.
