The Hangul Course · Lesson 1 of 6

How Hangul Works

Why Korean's alphabet was designed to be learned fast — and how letters stack into blocks.

10 min

Here's something most writing systems can't say: Hangul was designed — on purpose, by a team led by King Sejong, announced to the public in 1446 — with one explicit goal: that ordinary people could learn it fast. The royal commentary famously claimed a clever person could pick it up in a morning.

That wasn't marketing. By the end of this short course, you'll be reading real Korean. In this first lesson, you won't memorize a single letter — you'll learn the system, which makes every letter that follows feel predictable instead of random.

It's an alphabet — a small one

Korean is not like Chinese, with thousands of characters. Hangul has just 24 basic letters: 14 consonants and 10 vowels. Everything you'll ever read in Korean is built from these pieces, plus a few predictable combinations.

Letters stack into syllable blocks

The twist that makes Korean look mysterious: letters don't march in a line like English. They stack into square blocks, one block per syllable.

ㅎ+ㅏ+ㄴ한han · as in 한국, Korea

ㄱ+ㅜ+ㄱ국guk · country

So 한국 (han-guk, “Korea”) isn't two mysterious symbols — it's six letters, neatly packed into two boxes. Once you know the letters, you read each box left to right, top to bottom.

팁

Every block starts with a consonant, then a vowel — sometimes with a final consonant underneath. If a syllable starts with a vowel sound, the silent placeholder ㅇ holds the consonant seat. Korean blocks are tidy like that.

The shapes draw your mouth

This is the part that makes learners fall in love. The five base consonant shapes are little diagrams of your mouth making the sound:

ㄱg / kback of tonguethe tongue root rising to block the throat

ㄴntongue tipthe tongue tip touching behind the teeth

ㅁmlips togethera closed mouth, drawn as a box

ㅅsair past teeththe shape of a tooth

ㅇsilent / ngopen throata circle — the open throat

And there's a rule on top: add a stroke, get a stronger sound. ㄴ (n) gains a stroke to become ㄷ (d); ㄷ gains one more to become ㅌ (t). The alphabet isn't a list to memorize — it's a family tree.

The vowels carry a philosophy

Vowels are built from three strokes the inventors chose deliberately: a dot for sky (now a short stroke), a horizontal line for earth (ㅡ), and a vertical line for person (ㅣ). Every Korean vowel is some arrangement of sky, earth, and person. You'll meet them properly in Lesson 2.

Try it — no memorizing needed

You already know 한 and 국. Use just that:

How many letters (not blocks) are in 한국?Show answer

Six — ㅎ ㅏ ㄴ in the first block, ㄱ ㅜ ㄱ in the second. Two syllables, six letters.

The word 나 starts with ㄴ. Where is your tongue when you say “n” — and what does ㄴ's shape show?Show answer

The tongue tip touches just behind your upper teeth — and ㄴ is a drawing of exactly that: the tongue tip raised at the front.

What you just learned

Hangul is a small, deliberately designed alphabet — 24 basic letters.
Letters stack into one block per syllable; read each block left to right, top to bottom.
Consonant shapes diagram your mouth; extra strokes mean stronger sounds.
Vowels are built from sky (·), earth (ㅡ), and person (ㅣ).
