Abstract
Onya Darat is a language spoken, with great dialectal variation, in the interiorof western Borneo. It is the southernmost member of Land Dayak, a branchof the Austronesian language family. This article reports on the developmentof a writing system for Onya Darat. In addition to five vowels and 19 simpleconsonants, Onya Darat also exhibits three series of complex oral-nasalsegments: prenasalized oral stops, preoralized nasals, and postoralized nasals.An analysis of the Onya Darat sound system reveals that of these three seriesonly postoralized nasals are distinctive and therefore need to be representedin the writing system. The proposed orthography, developed with the aid ofnative speakers, represents all and only the phonemes of Onya Darat withoutresorting to diacritics or special characters
