Australian Sign language

Walpiri is an independently developed Aboriginal language that is widely understood and also used by non-deaf members.

While many neighbouring language groups such as Arrernte and the Western Desert Language have auxiliary sign languages, Warlpiri Sign Language, along with Warumungu Sign Language, appears to be the most well developed and widely used — it is as complete a system of communication as spoken Warlpiri. This is possibly due to the tradition that widows should not speak during an extended mourning period which can last for months or even years; during this time they communicate solely by sign language.

In Warlpiri communities, widows also tend to live away from their families, with other widows or young single women. As a result, it is typical for Warlpiri women to have a better command of the sign language than men, and among older women at Yuendumu, Warlpiri Sign Language is in constant use, whether they are under a speech ban or not.[1] However, all members of the community understand it, and may sign in situations where speech is undesirable, such as while hunting, in private communication, across distances, while ill, or for subjects that require a special reverence or respect. Many also use signs as an accompaniment to speech.
