While working with Australia’s Lajamanu Aboriginal population in remote sections of the Tanami Desert, linguist Carmel O’Shannessy identified “a [new] language system, independent of … other languages” spoken by about 300 people. Since her initial discovery in the late 1990s, O’Shannessy has studied the language and its grammatical structure, and now her findings have been published this month in the journal Language (PDF).
