Avunculate

Kinship Institutions

The avunculate is a formal or informal kinship institution centered on a distinctive relationship between a maternal uncle and his sister's children, defined by the Oxford English Dictionary as the special relationship existing in some societies between a maternal uncle and his sister's son, with the term itself derived from the Latin avunculus, meaning maternal uncle. Early anthropological research on the avunculate concentrated on linking the institution to societies with matrilineal descent, though later scholarship broadened its study to societies with varying descent patterns; foundational theoretical work on the institution's function and prevalence came from anthropologists including Franz Boas, Alfred Radcliffe-Brown, and Claude Levi-Strauss beginning in the early twentieth century. The avunculate has been documented across a wide range of cultures, including formal customary privileges granted to nephews among the Kazakh and Kyrgyz peoples of Central Asia, avunculocal residence among the Apache of the southwestern United States, where maternal uncles bore responsibility for transmitting social values and behavioral norms to nephews, and comparable avunculocal residence patterns among the Chamorro people of the Mariana Islands and the Taino of the Turks and Caicos Islands.
