By the 1970s, only vestiges were left, making Bahing a case study of grammatical attrition and language death. Phonology. Bahing and the related Khaling language have synchronic ten-vowel systems. The difference of "monkey" vs. "human being" is difficult to perceive for speakers of even neighboring dialects, which makes for "an unlimited source of fun to  the Bahing people" (de Boer 2002 PDF). Morphology. Hodgson (1857) reported a middle voice formed by a suffix "-s(i)" added to the verbal stem, corresponding to reflexives in other Kiranti languages.
