한카, or "Hanka," refers to a traditional Korean script used for writing the Korean language. It consists of a combination of consonants and vowels, allowing for the formation of syllables. This script is essential for literacy in Korea and is used in various forms of media, education, and daily communication. The development of 한카 dates back to the 15th century, created by King Sejong the Great and his scholars. It was designed to improve literacy among the common people, making it easier to learn compared to classical Chinese characters, which were previously used. Today, 한카 is a vital part of Korean identity and culture.
