Three sisters hold key to preserving ancient San language (audio)

Three sisters from the Northern Cape, aged between 80 and 95, have become the driving force behind a quest to preserve a dying language. At 95, her sight almost totally gone, Ouma Hanna Koper, her younger sisters Griet Seekoei, 82, and Katrina Esau, 80, and their younger brother, Simon Sauel, 67, are among the only people able to speak the ancient San language of N|uu.
