Htanaw (Danau) is an Austroasiatic language spoken by some 3000 people in six villages in southern Shan State, Myanmar. The language is largely undescribed and has no written form. In a collaborative project of native speakers and international linguists, a practical orthography to write Htanaw with Burmese characters is being developed and language data collected and analyzed. The goal is to compile an accessible archive of Htanaw material, including texts, grammatical descriptions, and an online dictionary in English, Htanaw, and Burmese for community use as well as academic research.
