カリブ族
Later speculation placed the Karankawa language in the Cariban linguistic stock. Linguistic data suggests that the Karankawa name originated from the old Spanish Main, "Kalina," and a suffix from a Northern Carib tribe, "kxura,"meaning "people;" a compound emerges: Karinxkxura, meaning "Carib people." But this theory is disputed and ultimately, the origins of the name "Karankawa" remain unknown.
