Mengapa Hangul terdengar begitu jelas — aksara yang menggambar suara

Korean middle schoolers scribble on paper: "나는 Bㅏ보야." The friend beside them laughs and reads it aloud as "babo" (fool). In that kid's head, the Latin B and the Hangul ㅂ occupy the same slot. The joke works because Hangul was designed a little differently from the world's other writing systems.

Unusual even among phonetic scripts

The world's scripts fall into three rough families. Logographic (Chinese characters) draw meaning. Syllabic (Japanese kana) record syllables. Phonetic (Latin alphabet, Hangul) separate consonants and vowels. Hangul belongs to the third family — but within it, it's an unusual case.

Most alphabets can be described as "they happened to evolve, were used for a long time, and ended up like this." The Latin alphabet drifted from Phoenician through Greek to Rome, and today's shapes are the accumulated drift. Hangul is different. In 1443, it was designed in one stroke by a single leader, and proclaimed in 1446. The work of King Sejong and the scholars of the Hall of Worthies.

Consonants — letters that drew speech organs

There is a book that records the design principles of Hangul's consonants: Hunminjeongeum Haerye (1446). The book vanished for almost 500 years until it was accidentally discovered in Andong in 1940. Open the Haerye, and a stunning sentence appears: The consonants were drawn from the shape of the speech organs.

• ㄱ — the tongue root blocking the throat
• ㄴ — the tongue tip touching the upper gum
• ㅁ — the shape of the lips
• ㅅ — the shape of the teeth
• ㅇ — the round shape of the throat

Slowly pronounce each consonant while watching a mirror, and you'll see — your mouth really does make that shape. This isn't a script that was invented. It's a script that drew sound. No writing system in the world has ever been designed with this kind of logic.

Vowels — heaven, earth, and human

The vowels are even more philosophical. Memorize three basic symbols.

• · (heaven) — a dot no longer used, once present in old Hangul
• ㅡ (earth) — the flat ground
• ㅣ (human) — a standing person

Combine these three and you generate ㅏ, ㅓ, ㅗ, ㅜ, ㅑ, ㅕ, ㅛ, ㅠ. Heaven meets human, and ㅏ is born. Heaven rests on earth, and ㅗ is born. The Eastern philosophical principle of cheon-ji-in (heaven–earth–human) was turned, directly, into a writing system.

Why "Bㅏ보" works

Back to the earlier joke. Koreans can read "Bㅏ보" as "babo" because the Latin B and the Hangul ㅂ both perform the same function — a bilabial plosive, formed by pressing the lips together and releasing. Koreans remember their consonants not as symbols, but as sound functions. So even when B slips into the seat of ㅂ, the grammar of the script doesn't break.

Slot Latin letters into Hangul's consonant positions and most of them match: D=ㄷ, M=ㅁ, N=ㄴ, S=ㅅ, K=ㅋ. The reason Koreans are unusually accurate when transliterating foreign words into Hangul is the same: a script that drew sound can translate any other sound-based system with relative ease.

A people who did science with their writing

"Hangul is scientific" is a phrase Koreans repeat often. More precisely: Hangul is a rare script designed scientifically. And that design intent is written plainly in the Haerye itself: I pity the foolish people who wish to speak but cannot express their meaning; for them I create these letters.

A 15th-century king designing a script from the side of his people. Drawing the shapes of the speech organs into the consonants, encoding the structure of the universe into the vowels. That we still use this writing system is something, occasionally, I can barely believe.
