The Korean alphabet, known as Hangeul(Hangul), is a writing system for the Korean language created by King Sejong the Great, the 4th King of the Joseon Dynasty in 1443. The Korean alphabet was designed so that people with little education could learn to read and write.
A popular saying about the alphabet is, "A wise man can acquaint himself with them before the morning is over; even a stupid man can learn them in the space of ten days." The project was completed in late December 1443 or January 1444, and described in 1446 in a document titled Hunminjeong'eum (The Proper Sounds for the Education of the People), after which the alphabet itself was originally named.
Hangeul is composed of 14 consonant letters (ㄱ ㄴ ㄷ ㄹ ㅁ ㅂ ㅅ ㅇ ㅈ ㅊ ㅋ ㅌ ㅍ ㅎ) and 10 vowel letters (ㅏ ㅑ ㅓ ㅕ ㅗ ㅛ ㅜ ㅠ ㅡ ㅣ). It can express virtually all the sounds produced by nature and humans. Hangeul is a very efficient and easy script to learn and use, and most of all, its promulgation was exactly recorded, which is unique in the world.
