"Another expedition journeyed far to the east, across the Panhandle of Texas, and contacted a party of Caddoan Indians. These were Hasinai, but the Spaniards called them Tejas, from the Caddoan Teychas, meaning "allies" or "friends." This word was spelled "Texas" frequently in old Spanish, in which the "x" was substituted for a "j" sound, and from this mistaken tribal name the land derived its name."
