藏缅语系, or the Sino-Tibetan language family, is a major language family that includes languages spoken primarily in Tibet, Myanmar, and parts of China. It is divided into two main branches: Tibeto-Burman and Sinitic. The Tibeto-Burman languages are diverse, with many dialects and languages, while Sinitic languages include Mandarin and other Chinese dialects. The languages in the 藏缅语系 share certain linguistic features, such as tonal distinctions and agglutinative structures. This language family is significant for understanding the cultural and historical connections among the peoples of the Himalayas and surrounding regions.
