Warlpiri society divides every person, from birth, into one of eight named subsections, a kinship system that governs who may marry whom, who stands in what obligation to whom, and who holds standing to speak for a given tract of Jukurrpa, Dreaming law, in ceremony. It is not a religious ornament on top of the kinship system; the two are the same structure looked at from two directions, since a person's subsection is inseparable from which ancestral tracks and which ceremonial responsibilities belong to them.
Ceremony under this system is not one fixed event but a working set of practices tied to specific life passages and specific needs: singing, dancing and ceremony mark initiation and other transitions, are called on to address illness, and are held around childbirth and to support fertility, each drawing on the subsection and Dreeaming-track obligations of the people involved rather than on a single officiant class. Widows, notably, are not compelled to remarry under this system and hold a recognized and significant place in Warlpiri society in their own right.
Responsibility for the deeper content of this law, what the article on Warlpiri identity calls "the big secrets" of the ceremonies and the Jukurrpa they enact, rests with yampurru, senior knowledge holders drawn from both men and women, whose standing to hold and transmit that knowledge is itself assigned by the subsection system. With roughly five to six thousand Warlpiri people and about three thousand remaining speakers of the language, the system that assigns this knowledge remains an active, functioning structure rather than a historical description.
