Australian Aboriginal avoidance practices
Naming the dead
Traditionally, this meant avoiding referring to a dead person by name directly after their death as a mark of respect[4] – and also because it is considered too painful for the grieving family. Today, the practice continues in many communities, who have also come to avoid sharing electronic impressions of the person. Most television stations use a disclaimer warning Aboriginal and Torres Strait Islander viewers that the program may contain images and voices of dead Indigenous people (as recommended by the Australian Broadcasting Corporation[5]).
The avoidance period may last one or more years. The person can still be referred to in a roundabout way, such as, "that old lady", or by their generic skin name, but not by first name.[4] In some Central Australian communities, if a girl named Alice (for example) dies, "Alice" must be avoided in all contexts, so a township like Alice Springs would be referred to indirectly. Those living with the same name as one of the dead are called a substitute name during the avoidance period, much as "Kuminjay", used in the Pintubi-Luritja dialect,[6] or "Galyardu", which appears in a mid-western Australia Wajarri dictionary for this purpose.
This presents some challenges to indigenous people. In traditional society, people lived together in small bands of extended family, and name duplication was less common. Today, as people have moved into larger communities (with 300 to 600 people), the logistics of name avoidance have become increasingly difficult. Exotic and rare names have therefore become more common, particularly in Central Australia and desert communities, to deal with this new challenge.
