This report contains preliminary descriptive and comparative information on Gyalsumdo, a variety of Tibetan that is spoken in the lower Manang District of Nepal. Based on select lexico-phonetic data recorded from one speaker in 2009 and 2010, and on data available from other languages of Manang and nearby Gorkhā District, we hypothesize its location within Tibetic (Central Tibetan). Gyalsumdo shares more features with Nubri, but we also note additional similarities to Kyirong Tibetan, and to Tamangic languages with which Gyalsumdo has had regular contact over several generations.
