Korean receives a new alphabetic expression
Fifteenth-century Joseon used Chinese characters for formal writing, while Korean speech posed difficulties for many readers. Sejong’s project produced a writing system in 1443, explained in the 1446 Hunminjeongeum and commentaries. Letters combined into syllables, with their design related to sound classification and articulation. Examples helped users understand combinations. Scholarly discussion, textual production and practical application accompanied the project as the court sought easier ways for residents to record their own language across different written activities.
Translation and household writing widen use
The script entered Buddhist translations, songs and instructional works, allowing Korean-language access to texts. Women and people with limited classical education increasingly used it in letters, narratives and household affairs. Authors and copyists adapted material for readers. Critics opposed the project, while classical Chinese retained roles in offices, examinations and scholarship. Both forms coexisted for long periods. Readers, resources and opportunity gradually widened use through temples, households and local reading, with different materials circulating among people whose opportunities and purposes shaped the development of written expression.
Publishing and schools change the script’s standing
Centuries of copying and printing preserved Korean expression before newspapers, modern schools and language movements enlarged public use. Nineteenth- and twentieth-century publishing developed spelling and teaching practices, while colonial rule made language politically contested. Textbooks, journalism and literature familiarized readers with shared forms. The 1446 commentary preserves early design; later editors, teachers and ordinary writers continually developed its applications. Present-day writing therefore contains accumulated practices shaped by prolonged work in education, publishing and everyday communication.
