Other comments: Atakapa (/əˈtækəpə, -pɑː/, natively Yukhiti]) is an extinct language isolate native to southwestern Louisiana and nearby coastal eastern Texas. It was spoken by the Atakapa people (also known as Ishak, after their word for "the people". The language became extinct in the early 20th century.
Classification: While considered an isolate, there have been attempts to connect Atakapa with other languages of the Southeast. In 1919 John R. Swanton proposed a Tunican language family that would include Atakapa, Tunica, and Chitimacha; Morris Swadesh would later provide work focusing on connections between Atakapa and Chitimacha. Mary Haas later expanded the proposal by adding Natchez and the Muskogean languages, a hypothesis known as Gulf. These proposed families have not been proven. The similarities between Atakapa and Chitimacha, at least, may be attributable to periods of "intense contact [between speakers of the two languages] owing to their geographic proximity."
Geographical variation: According to Swanton (1929) and Goddard (1996), Atakapa could be classified into Eastern and Western varieties. Eastern Atakapa is known from a French-Atakapa glossary with 287 entries, compiled in 1802 by Martin Duralde. The speakers interviewed by Duralde lived in the easternmost part of Atakapa territory, around Poste des Attakapas (Saint Martinville), now Franklin, Louisiana.
Western Atakapa is the better-attested of the two varieties. In 1885, Albert Gatschet collected words, sentences, and texts from two native Atakapa speakers, Louison Huntington and Delilah Moss at Lake Charles, Louisiana. John R. Swanton worked with another two speakers near Lake Charles: Teet Verdine in 1907, and Armojean Reon in 1908. Additionally, in 1721, Jean Béranger collected a small vocabulary from captive speakers in Galveston Bay. John Swanton argued that the Béranger vocabulary represented the Akokisa language, spoken by a people who lived somewhat inland from Galveston Bay. There is little evidence to support his assertion.

Atakapa has only recorded traditional numerals from 1 to 10 years ago, not sure if they were used a traditional decimal or vigesimal system before, New data for numbers after ten is required.
