The Tibetan script is a segmental writing system, or abugida, forming a part of the Brahmic scripts, and used to write certain Tibetic languages, including Tibetan, Dzongkha, Sikkimese, Ladakhi, Jirel and Balti. Its exact origins are a subject of research but is traditionally considered to be developed by Thonmi Sambhota for King Songtsen Gampo.
The Tibetan script has also been used for some non-Tibetic languages in close cultural contact with Tibet, such as Thakali and Nepali. The printed form is called uchen script while the hand-written form used in everyday writing is called umê script. This writing system is especially used across the Himalayan Region.
