Hangeul

Celebrating the alphabet of the people.

Letter Anatomy

Each shape traces the mouth. Each stroke encodes speech.

vertical stroke horizontal base

Giyeok

Modeled after the shape of the tongue touching the back of the palate. The simplest consonant form, demonstrating Hangeul's principle of iconic representation -- each letter mirrors the speech organ that produces its sound.

/g/, /k/
tongue tip gum ridge

Nieun

Represents the tongue touching the upper gum ridge. Each consonant shape maps directly to the position of speech organs during pronunciation. Nieun adds a horizontal stroke to show the tongue's forward contact point.

/n/
closed lips

Mieum

The square form represents the closed shape of the lips. Among the five basic consonants, Mieum captures the bilateral press of the mouth -- geometry encoding human anatomy with elegant precision.

/m/
teeth shape

Siot

Shaped like a tooth. The triangular form represents the shape of the teeth through which air passes to create the sibilant sound. Its simple geometry connects visual form directly to phonetic function.

/s/
open throat

Ieung

The circular form represents the open throat. When used as an initial consonant, it is silent -- the shape itself embodies absence of sound. As a final consonant, it voices the nasal /ng/. Emptiness made visible.

/ŋ/ or silent

Vowel Principles

Heaven, earth, and human -- three elements form every vowel.

· Heaven
— Earth
| Human
아 /a/
어 /eo/
오 /o/
우 /u/

Syllable Blocks

Hangeul's unique innovation: individual letters combine into syllable blocks. Initial consonant, medial vowel, and optional final consonant stack into a single square unit. (han) assembles from ㅎ + ㅏ + ㄴ.

A wise person can acquaint himself with them before the morning is over; even a stupid person can learn them within the space of ten days.

슬로운 사람은 하루 아침에 깨우치고, 어리석은 사람도 열흘만에 배울 수 있다.

Hunminjeongeum Haerye, 1446
