The Kitsai language is now extinct, its members having been absorbed into the Witchita tribe in the 19th century. Caddo, Wichita, and Pawnee are presently spoken in Oklahoma by small handfuls of elders. Arikara is spoken on the Fort Berthold Reservation in North Dakota. Some of the languages were formerly more widespread; the Caddo, for example, used to live in northeastern Texas, southwestern Arkansas, and northwestern Louisiana as well as southeastern Oklahoma. The Pawnee formerly lived along the Platte River in what is now Nebraska.
External relations
Adai, a language isolate known only from a 275-word list, may be a Caddoan language, but the documentation is too scanty to determine with certainty. Wallace Chafe finds the relationship unlikely.
Numerous attempts to link the Caddoan and Iroquoian languages in a Macro-Siouan language family are suggestive but remain hypothetical. Similar attempts to find a connection with the Algonkian languages has been partially useful, but not enough evidence for linguists to propose a hypothetical Macro-Algonkian/Iroquoian language family.citation needed
