Which languages are included in the Tibetic division of Tibeto-Burman?

The Tibetic division—often referred to as Bodic—is a subgroup within the Tibeto-Burman family that encompasses a variety of languages and dialects spoken throughout Tibet and the Himalayas.1

Rather than a single uniform language, Tibetic is understood in the widest sense as a collection of related linguistic forms. Scholars typically categorize the Tibetan language itself into four primary dialect groups:1

• Central: Includes the widely spoken dialect of Lhasa.2
• Southern: Primarily found in Sikkim, Bhutan, and Nepal.2
• Northern: Spoken in northern Tibet.2
• Western: Known for being more conservative in their sound systems, having better preserved the initial consonant clusters and final stops of Old Tibetan.2

These languages are geographically distributed across the Tibet Autonomous Region, the Himalayan nations, and parts of northern India.21
