Reading Hangul — 5 shapes, 2 moves, and one afternoon

The “learn it in a morning” claim is true, and it is true for a reason: the letters are not arbitrary. Here is the system, then real words from the practice sets to read.

Five shapes, two moves

Hangul was designed, not inherited, and the design is visible. Five base consonants are diagrams of the mouth making them: ㄱ the back of the tongue rising, ㄴ the tip touching the ridge, ㅁ the lips, ㅅ a tooth, ㅇ the throat. Everything else is those five with strokes added or doubled.

ㄱ → ㅋ → ㄲ	add a stroke → aspirated ㅋ · double → tense ㄲ
ㄴ → ㄷ → ㅌ → ㄸ	ㄴ gains strokes to become ㄷ then ㅌ, doubled ㄸ
ㅁ → ㅂ → ㅍ → ㅃ	ㅁ → ㅂ → ㅍ, doubled ㅃ
ㅅ → ㅈ → ㅊ → ㅆ ㅉ	ㅅ → ㅈ → ㅊ, doubled ㅆ ㅉ
ㅇ → ㅎ	ㅇ → ㅎ

The extra stroke means more air and the doubling means more tension. So the shape tells you the sound — which is why nineteen consonants is not nineteen things to memorise.

Vowels are two lines and a dot

A vertical line ㅣ, a horizontal line ㅡ, and a dot that is now written as a short stroke. Where the dot sits gives you the four core vowels; a second dot adds a y in front.

ㅣ + 점 오른쪽 → ㅏ	a
ㅣ + 점 왼쪽 → ㅓ	eo
ㅡ + 점 위 → ㅗ	o
ㅡ + 점 아래 → ㅜ	u
점 하나 더 → ㅑ ㅕ ㅛ ㅠ	ya yeo yo yu — the second stroke always means y

That is ten vowels from almost nothing. The remaining eleven are combinations of these — ㅐ is ㅏ+ㅣ, ㅘ is ㅗ+ㅏ — and you can decode them on sight once the ten are in.

Letters stack into blocks

Korean does not write letters in a line; it packs each syllable into a square. Consonant first, vowel second, optional final consonant at the bottom. A tall vowel goes to the right; a flat vowel goes underneath.

ㄱ + ㅏ → 가	tall vowel → side by side
ㄱ + ㅗ → 고	flat vowel → stacked
ㄱ + ㅏ + ㅇ → 강	the final consonant sits at the bottom
ㄱ + ㅗ + ㅁ → 곰	same, with ㅁ underneath
ㅇ + ㅣ → 이	ㅇ at the start is silent — it is a placeholder so the block has a consonant slot filled

That silent ㅇ trips everyone once. At the bottom of a block the same letter is a real sound, ng — 강 ends the way sing does.

Now read these — they are from the practice sets

Every word below actually appears in the spoken sets on this site, and none of them has a final consonant, so they decode straight through. Sound them out; do not look for meanings yet.

그거 · 너무 · 다시	that thing · too much · again
모두 · 비가 · 소리	everyone · rain (subject) · sound
이거 · 제가 · 차가	this thing · I (polite) · car (subject)
커피 · 타요 · 파티 · 해요	coffee · to ride · party · to do

Then the doubled letters, which are less common at the start of a word but very common inside one:

꼭 · 또	definitely · again
빨리 · 써도	quickly · even if you write
쪽 · 짧게	side · shortly
를 · 런던	(object particle) · London

One letter almost never starts a word

Across 50,013 words in this site's Korean sentences, only 106 — 0.21% begin with ㄹ, and nearly all of those are either the particle 를/로 or a borrowed name like 런던. This is not an accident: South Korean spelling has a rule (두음법칙) that moves an initial ㄹ to ㄴ or ㅇ.

Useful in practice: if a word starts with ㄹ, expect a loanword. And the sound itself sits between English l and r — closer to the flap in butter than to either letter.

The part nobody tells you next

You can now read every Korean word on this site. You will still not recognise them when spoken, and that is not a failure of your reading — the letters are accurate about the parts a word is built from, and speech smooths the joins.

That gap has its own rules and they are short: why Korean doesn't sound like it's spelled. Read it right after this one — reading Hangul without it produces a learner who can decode a page and understand nothing spoken.
