Kim Jong Un is a North Korean politician who has been supreme leader of North Korea since 2011 and the leader of the Workers' Party of Korea (WPK) since 2012. He is the third son of Kim Jong Il, who was the second supreme leader of North Korea, and a grandson of Kim Il Sung, the founder and first supreme leader of the country.

Korean is the native language for about 81 million people, mostly of Korean descent. It is the official and national language of both North Korea and South Korea. The language has notable differences in each of the Koreas, in part owing to different official standardizations of the language. They are still largely mutually intelligible, however. South Korean newspaper Daily NK has claimed North Korea criminalizes the use of the South's standard language with the death penalty, and South Korean education and media often portray the North's language as alien and uncomfortable.
