한글의 아름다운 세계
The beautiful world of the Korean alphabet
The shape of ㄱ (giyeok) mimics the root of the tongue blocking the back of the throat. King Sejong designed these consonants by observing how the tongue curves against the soft palate to produce velar sounds.
From this single angular shape, the entire velar consonant family is born: adding a stroke creates ㅋ (kieuk) for the aspirated /kh/, and doubling creates ㄲ (ssang-giyeok) for the tensed /kk/.
The letter ㄴ (nieun) depicts the tongue tip touching the alveolar ridge. This simple L-shape captures the exact position of the tongue when producing the /n/ sound.
This group demonstrates Hangul's systematic genius: ㄷ (digeut) adds a stroke for /d/, ㄹ (rieul) curls the shape for /r-l/, and ㅌ (tieut) adds another stroke for the aspirated /th/.
The square shape of ㅁ (mieum) represents the closed mouth — lips pressed together to produce the /m/ sound. It is the most intuitive of all Hangul consonants: a box for a closed mouth.
Adding vertical strokes creates ㅂ (bieup) for the plosive /b/, and further modification yields ㅍ (pieup) for the aspirated /ph/.
The triangular form of ㅅ (siot) represents the shape of the teeth as seen from the side. Air flows between the pointed teeth to create the sibilant /s/ sound.
This dental family expands logically: ㅈ (jieut) adds a bar for the affricate /j/, ㅊ (chieut) adds another for /ch/, and ㅆ (ssang-siot) doubles the shape for the tensed /ss/.
The circle of ㅇ (ieung) represents the round, open throat. When used at the beginning of a syllable, it is silent — a placeholder. At the end, it produces /ng/.
Its companion ㅎ (hieut) adds a horizontal stroke, representing air being pushed through the throat to create the aspirated /h/ sound. Together, they complete the five articulatory groups of all Hangul consonants.
