Retired in ISO 639-3: split into Gwak [jgk] and Bankal [jjr]
Excerpt from change request document:
Intelligibility and lexical similarity between Bankal and Gwak are marginal.
Speakers of Gwak, Bankal, Duguri, Mbat, and Kantana all consider themselves to be one Jarawa people, descended from the same ancestors and speaking a common Jar language. There is no significant body of existing Jar literature.
