Warlpiri is part of the Yapa/Ngarrkic group of Pama-Nyungan languages. About 3,000 people out of a total population of 5,000 speak Warlpiri. Most also speak English, and many speak other aboriginal languages, such as Arrernte, Jaru and Warumungu, as well. The traditional land of the Warlpiri is in the Northern Territory of Australia to the north and west of Alice Springs, and the largest settlement is Yuendumu.
Warlpiri is written with the Latin alphabet without any diacritical marks. A spelling system for the language was first devised by Lothar Jagst during the 1950s and has been revised slightly since then.
