Hangeul

Writing is a cornerstone of civilization, a crucial invention that better allows peoples to accumulate and pass down knowledge and preserve cultures. There are currently some 6,909 living languages in the world, yet only a minority of these are written, and of these just a handful have their own unique writing systems.
Hangeul, the indigenous writing system of Korea, is one of them. Promulgated in 1446, Hangeul is an ingenious system that utilizes forward-thinking and scientific linguistic theories and principles of Korean traditional culture to perfectly express the sounds of the Korean language. Invented by the brilliant King Sejong the Great, the alphabet has been widely lauded by scholars the world over for its advanced phonetic system and ease of use.
