According to the Marubos, the current-day Marubo ethnic group is composed of several tribes who spoke mutually intelligible Panoan languages ... and the language of one of these groups (tje Shainawabo people) is what the Marubos speak now, and a second language was in part retained as a ceremonial/shamanic language, called Asan ikiki by the Marubos ... However, the oral history does not match the linguistic facts, as Asan ikiki seems to actually be Marubo with substituted words, which may or may not originate from a sister language. (p.47)
