 Writing system
한글(Hangeul or Hangul) is the unique writing system of Korean, which was created and promulgated by by King Sejong of Joseon Dynasty, a historic kingdom of Korea. It was completed in late 1443 and published with a book titled HunMinJeongEum in 1446.
It is a featural script and has hybrid feature of alphabet and Syllabary. Each letter of Hangul is alphabetic but it is always used in a syllabic block, not alone. Therefore, 2 or more letters should be grouped as one character to represent elements of the Korean language.
ㄱ, ㄴ, ㄷ, ㄹ, ㅁ, ㅂ, ㅅ, ㅇ, ㅈ, ㅊ, ㅋ, ㅌ, ㅍ, ㅎ, ㅏ, ㅑ, ㅓ, ㅕ, ㅗ, ㅛ, ㅜ, ㅠ, ㅡ, ㅣ
Auxiliary writing system of Korean is Hanja(漢字), which is a logogram derived/borrowed from Chinese character or the Korean name of Chinese character itself. Hanja can not wholly represent Korean language itself but it may be used for some Korean words coined using Chinese characters. Generally, Korean language is exclusively written by Hangul nowadays.
