Abstract: A nuclear family, that is the social unit comprising a husband, wife(s) and their children, is one of the significant core elements around which the great majority of societies are built. An individual's most immediate social and emotional relationships, those between children and parents, between husband and wife, and between siblings are encapsulated within it. How these relationships are realised in actual practice is partly dependent upon the form marriage takes. In this paper, I analyse Warlpiri marriage as practice and institution by drawing on and comparing material by Mervyn Meggitt (from his work at Lajamanu in the 1950s), Diane Bell (based on her work at Alekarenge in the 1970s) and my own data from my fieldwork at Yuendumu (from the mid 1990s and onward). My aim is to explore the following questions: What constitutes a marriage in Warlpiri eyes today? Are there continuities with the past? What has changed since the 1950s? And, what do these continuities and changes mean in regard to the way Warlpiri people live their lives today?
