Pre-contact distribution of Adai

Adai (also Adaizan, Adaizi, Adaise, Adahi, Adaes, Adees, Atayos) is an extinct Native American language that was spoken in northwestern Louisiana.

Classification

It was once proposed that there may be a connection between Adai and the nearby Caddoan languages, but this now seems unlikely.3

Vocabulary

Adai is known only from a list of 275 words from 1804 by John Sibley.4
