The Dzongkha Development Commission (རྫོང་ཁ་གོང་འཕེལ་ལྷན་ཚོགས), also called the DDC, is the pre-eminent body on matters pertaining to the Dzongkha language. The DDC was officially established in 1986 by Jigme Singye Wangchuk, the fourth king of Bhutan, to preserve and promote the use of Dzongkha as the national language of Bhutan.
The Dzongkha Development Commission consists of two parts: the Commission itself having nine eminent members (or commissioners) chaired by the Prime Minister of Bhutan; and the DDC Secretariat which carries out the day to day work of the Commission.
The body has the task of acting as an official authority on the language. It is charged with promoting the use of Dzongkha; researching and publishing official dictionaries and grammar of the language; developing new lexical terninology; and developing software and fonts to support the language.
