한글 is the writing system of the Korean language, created in the 15th century by King Sejong the Great and his scholars. It was designed to improve literacy among common people, as the existing writing systems were complex and difficult to learn. 한글 consists of 14 basic consonants and 10 basic vowels, which can be combined to form syllables. The structure of 한글 is unique, as it groups letters into blocks that represent syllables. Each block typically contains a consonant followed by a vowel, and sometimes an additional consonant. This phonetic system makes 한글 relatively easy to learn and use, contributing to its widespread adoption in both North and South Korea.
