Sino-Tibetan, also cited as Trans-Himalayan in a few sources, is a family of more than 400 languages, second only to Indo-European in number of native speakers. The vast majority of these are the 1.3 billion native speakers of Sinitic languages. Other Sino-Tibetan languages with large numbers of speakers include Burmese (33 million) and the Tibetic languages (6 million). Other languages of the family are spoken in the Himalayas, the Southeast Asian Massif, and the eastern edge of the Tibetan Plateau. Most of these have small speech communities in remote mountain areas, and as such are poorly documented.
Several low-level subgroups have been securely reconstructed, but reconstruction of a proto-language for the family as a whole is still at an early stage, so the higher-level structure of Sino-Tibetan remains unclear. Although the family is traditionally presented as divided into Sinitic (i.e. Chinese languages) and Tibeto-Burman branches, a common origin of the non-Sinitic languages has never been demonstrated. Although Chinese linguists generally include Kra–Dai and Hmong–Mien languages within Sino-Tibetan, most other linguists have excluded them since the 1940s. Several links to other language families have been proposed, but none have broad acceptance.
A genetic relationship between Chinese, Tibetan, Burmese and other languages was first proposed in the early 19th century and is now broadly accepted. The initial focus on languages of civilizations with long literary traditions has been broadened to include less widely spoken languages, some of which have only recently, or never, been written. However, the reconstruction of the family is much less developed than for families such as Indo-European or Austroasiatic. Difficulties have included the great diversity of the languages, the lack of inflection in many of them, and the effects of language contact. In addition, many of the smaller languages are spoken in mountainous areas that are difficult to reach, and are often also sensitive border zones.

The Tibeto-Burman languages are the non-Sinitic members of the Sino-Tibetan language family, over 400 of which are spoken throughout the Southeast Asian Massif ("Zomia") as well as parts of East Asia and South Asia. Around 60 million people speak Tibeto-Burman languages. The name derives from the most widely spoken of these languages, Burmese and the Tibetic languages, which also have extensive literary traditions, dating from the 12th and 7th centuries respectively.
Southeast Asia, also spelled South East Asia and South-East Asia, and also known as Southeastern Asia, South-eastern Asia or SEA, is the geographical south-eastern region of Asia, consisting of the regions that are situated south of mainland China, east of the Indian subcontinent, and north-west of mainland Australia which is part of Oceania. Southeast Asia is bordered to the north by East Asia, to the west by South Asia and the Bay of Bengal, to the east by Oceania and the Pacific Ocean, and to the south by Australia and the Indian Ocean.
