HANGUL GUIDE · 4 LESSONS

How Hangul Works

Hangul was not inherited — it was designed. In 1443 the consonants were drawn from the shape the mouth makes, and the vowels from three strokes: sky, earth and human. Every letter has a reason, and knowing the reason halves what you have to memorise.

1 CONSONANTS

Drawings of a mouth making a sound

There are only five basic consonants. Each one is a picture of what the mouth actually does to make that sound.

Molar soundvelar · /k/
tongue root

The back of the tongue rises to close off the throat. The bend in ㄱ is that cross-section.

Tongue soundalveolar · /n/
tongue tip

The tip of the tongue touches the ridge behind the upper teeth. ㄴ is that tongue, seen from the side.

Lip soundbilabial · /m/
closed lips

A closed mouth seen head-on. ㅁ is the square the lips themselves make.

Tooth soundsibilant · /s/
front teeth

The pointed shape of the front teeth. ㅅ draws the air hissing between them.

Throat soundglottal · /ŋ/
throat

The round cross-section of an open throat — the sound made furthest back.

Add a stroke, strengthen the sound

The remaining consonants are not new letters. They are the basic five with strokes added, and each added stroke pushes more breath through. A change in shape is a change in sound.

BASE+1 STROKE+2 STROKESWHAT CHANGES
kThe throat closes, then bursts open with breath
ntA touching tongue becomes a blocking one, then a bursting one
mpThe lips part and the breath bursts through
stɕʰA hissing sound becomes one that sticks, then releases
ŋhBreath rubs its way out through the open throat

ㄹ sits outside this rule: it was drawn separately, for the tongue flicking as it rolls. The doubled consonants ㄲ ㄸ ㅃ ㅆ ㅉ stack the same letter twice, meaning the throat tightens further.

On the keyboard

A doubled consonant is not a new key — it is the basic consonant with Shift. Hold Shift on ㄱ and you get ㄲ. The principle of adding to strengthen survives in the layout itself.
