A celebration of King Sejong's 1443 invention, drafted on blueprint paper for October 9th.
Hangeul groups its 14 basic consonants by point of articulation. Each shape mirrors the position of the speech organ that produces it -- a phonetic blueprint hidden in the line.
The base shape ㄱ outlines the tongue arching toward the soft palate. Add a stroke for aspirated ㅋ; double it for the tense ㄲ.
Hooked ㄴ renders the tongue's curl. ㄷ, ㅌ, ㄸ add deliberate strokes for plosive intensity, while flowing ㄹ traces the lateral path.
The square of ㅁ is the closed mouth. ㅂ, ㅍ, ㅃ stack additional strokes -- each line adding pressure and tension to the release.
Every Hangeul syllable is a 2-D block assembled from an initial consonant, a medial vowel, and an optional final consonant. Hover the labels to highlight each part.

King Sejong the Great, working privately in the Hall of Worthies, completes a phonetic alphabet of 28 letters designed to be learned in a single morning. The project is hidden from yangban scholars who consider Classical Chinese sufficient.
Hunminjeongeum (훈민정음) -- "The Correct Sounds for the Instruction of the People" -- is promulgated. The accompanying treatise explains the phonetic and philosophical reasoning behind every consonant and vowel shape.
The Gabo Reform decrees that Korean state documents be written in Hangeul (or mixed Hangeul-Hanja). After four centuries of marginalisation as eonmun ("vernacular script"), the alphabet enters official use.
The Independent, founded by Seo Jae-pil, publishes Korea's first all-Hangeul newspaper. Mass literacy in the script accelerates rapidly; vernacular journalism becomes possible for ordinary readers.
After Japanese colonial suppression of the Korean language, Hangeul is reinstated in education and public life. Linguists like Choe Hyeon-bae publish systematic spelling reforms.
Hangeul Day -- October 9th -- is restored as an official public holiday in South Korea, commemorating the publication of Hunminjeongeum. The day is celebrated with public readings, calligraphy, and design.
Press a vowel. Hangeul's basic vowels are built from three philosophical primitives: heaven (ㆍ), earth (ㅡ), and human (ㅣ).
