Language serves as one of the most significant aspects in the human society. In addition, it is a vital component of human culture. In fact, language refers to the human ability to obtain and use complicated systems of communication. Specifically, a language can be considered as any particular example of such a system. As usual, the types of language vary from nations to nations. In particular, Korean is the official language of South Korea and North Korea. Meanwhile, it is one of the two official languages in Yanbian Korean Autonomous Prefecture in China. There are approximately 80 million Korean speakers around the globe.
Before the 19th century, Koreans wrote and adapted hanja (Chinese characters) to conduct communications. Specifically, hanja was adapted and complemented by phonetic systems, such as idu, hyangchal, and gugyeol. In the 15th century, Sejong the Great decided to establish Hunmin Jeongum to regulate the Korean language, which helped to commission a writing system called Hangul in the nation. However, Hangul was not widely used at that time. In the early 20th century, Koreans started to widespread use Hangul as the yangban aristocracy’s prefers to use hanja. Hanja finally became the official language in the country. After the Second World War, the whole nation was divided as South Korea and North Korea. At that time, South Korea forbade the uses of hanja in the country. However, this change of language had brought many inconveniences to the Koreans. As a consequence, South Korea had to continue the use and education of hanja.
