Narangga (also Narungga) is an extinct Australian Aboriginal language formerly spoken by the Narungga people in Yorke Peninsula, South Australia. As a result of the colonisation of Australia, the Narangga language fell into disuse within several generations. Nevertheless, Narangga continued to be documented into the 20th century and the 1980s saw a community reclamation of the Narangga language by the Aboriginal community. As a result of revival efforts, the language along with Narangga culture is now being taught around the Yorke Peninsula, from Moonta and Maitland Area Schools to Point Pearce. (from wikipedia)
