Sino Tibetan language spoken in Bhutan

Dzongkha (; ) is a Sino Tibetan language that is the official and national language of Bhutan. It is written using the Tibetan script. The word means "the language of the fortress", from "fortress" and "language". as of 2013, Dzongkha had 171,080 native speakers and about 640,000 total speakers. There are also some native speakers near the Indian town of Kalimpong, once part of Bhutan but now in North Bengal, and in Sikkim. Dzongkha was declared the national language of Bhutan in 1971. Dzongkha study is mandatory in all schools, and the language is the lingua franca in the districts to the south and east where it is not the mother tongue. The Bhutanese films Travellers and Magicians (2003) and Lunana: A Yak in the Classroom (2019) are in Dzongkha.

The Tibetan script used to write Dzongkha has thirty basic letters, sometimes known as "radicals", for consonants. Dzongkha is usually written in Bhutanese forms of the Uchen script, forms of the Tibetan script known as Jôyi "cursive longhand" and Jôtshum "formal longhand". The print form is known simply as Tshûm.

There are various systems of romanization and transliteration for Dzongkha, but none accurately represents its phonetic sound. The Bhutanese government adopted a transcription system known as Roman Dzongkha, devised by the linguist George van Driem, as its standard in 1991. It has a much more distant relationship to Standard Tibetan. Spoken Dzongkha and Tibetan are around 50% to 80% mutually intelligible, with the literary forms of both highly influenced by the liturgical (clerical) Classical Tibetan language, known in Bhutan as Chöke, which has been used for centuries by Buddhist monks. Chöke was used as the language of education in Bhutan until the early 1960s when it was replaced by Dzongkha in public schools. Although descended from Classical Tibetan, Dzongkha shows a great many irregularities in sound changes that make the official spelling and standard pronunciation more distant from each other than is the case with Standard Tibetan. "Traditional orthography and modern phonology are two distinct systems operating by a distinct set of rules."
