Hunminjeongeum

Hunminjeongeum (Korean: 훈민정음; Hanja: 訓民正音; lit. 'The Correct Sounds for the Instruction of the People') is a 1446 work that formally introduced the first native Korean alphabet. That alphabet was originally also called "Hunminjeongeum", although it is now widely called "Hangul" (international spelling; spelled in South Korea "Hangeul") or "Chosŏn'gŭl" (in North Korea). The term Hunminjeongeum is used in a number of different ways, often due to the various editions and sections of the text. The term is sometimes used to refer to only the first two sections of the text: the preface and description of Hangul. That "base" Hunminjeongeum is sometimes referred to as the Yeui (예의; 例義). There is also a commentary section, the Hunminjeongeum Haerye, that was published alongside the base Hunminjeongeum. Sometimes, the base Hunminjeongeum and Haerye together are referred to only as Hunminjeongeum. The base Hunminjeongeum was first published around October 1446 (Gregorian calendar) and authored by Joseon king Sejong the Great (r. 1418–1450). It was originally written in Classical Chinese using the Hanja script. It was later translated to the Korean language using Korean mixed script; such translated editions are called Eonhae (언해; 諺解; Ŏnhae). While the base Hunminjeongeum remained in the historical record, the Haerye was lost and forgotten. It was only rediscovered in 1940. The Hunminjeongeum and Haerye are considered to be among the most important works in the study of the Korean language. A copy of the full text, including the Haerye section, was designated a National Treasure of South Korea in 1962 and entered into the UNESCO Memory of the World Register in 1997.
