What is "dayuma"

Dayuma (also Dayumae) (born ca. 1930, - March 1, 2014) was a member of the Huaorani tribe and a citizen of Ecuador. She is a central figure in the Operation Auca saga, in that she was the first Huao convert to Christianity, as well as the missionaries' key to unlocking the Huaorani language, a language that had not been previously studied. Later Dayuma also became an influential figure in her tribe.
