Caddoan Languages - External Relations

External Relations

Adai, a language isolate known only from a 275-word list collected in 1804, may be a Caddoan language. The documentation is too scanty to determine with certainty. The Adai lived in Louisiana. The language of the Ais, who lived adjacent to the Caddo, was a distinct language, but was probably related to Caddoan. (Another unrelated people also called the Ais lived in Florida.) Some linguists believe that the Caddoan and Iroquoian languages may be connected in a Macro-Siouan language family, but work is suggestive and the theory remains hypothetical. Similar attempts to find a connection with the Algonquian languages has been partially useful. There is insufficient evidence for linguists to propose a hypothetical Macro-Algonquian/Iroquoian language family.
