Yolmo (Hyolmo) or Helambu Sherpa, is a Tibeto-Burman language of the Hyolmo people of Nepal (ISO 639-3: , GlottoCode: yolm1234). Yolmo is spoken predominantly in the Helambu and Melamchi valleys in northern Nuwakot District and northwestern Sindhupalchowk District. Dialects are also spoken by smaller populations in Lamjung District and Ilam District and also in Ramecchap District (where it is known as Syuba). It is very similar to Kyirong Tibetan and less similar to Standard Tibetan and Sherpa. There are approximately 10,000 Yolmo speakers, although some dialects have larger populations than others.
