ABSTRACT
The Korean writing system “Hangul” is one of the most scientific and systematic writing systems in the world. Hangul comprises an alphabet of 21 vowel and 19 consonant symbols. The system was invented in 1443 by King Sejong the Great and his group of royal scholars during the Chosun dynasty of Korea. Hangul has a total of 21 vowel symbols. Among them are 11 basic vowel and ten double vowel symbols. Ten double vowel symbols are made by either adding an additional stroke to some of the above basic vowel symbols or by combining basic vowel symbols. The basic unit of a Korean letter is the syllable. A complete Korean written letter must have at least one consonant and one vowel symbol.
