From the site:
Korean, a language spoken by about 63 million people in South Korea, North Korea, China, Japan, Uzbekistan, Kazakhstan and Russia. The relationship between Korean and other languages is not known for sure, though some linguists believe it to be a member of the Altaic family of languages. Grammatically Korean is very similar to Japanese and about 70% of its vocabulary comes from Chinese.
The Korean alphabet was invented in 1444 and promulgated it in 1446 during the reign of King Sejong (r.1418-1450), the fourth king of the Joseon Dynasty. The alphabet was originally called Hunmin jeongeum, or "The correct sounds for the instruction of the people", but has also been known as Eonmeun (vulgar script) and Gukmeun (national writing). The modern name for the alphabet, Hangeul, was coined by a Korean linguist called Ju Si-gyeong (1876-1914).
