Day 1: Hangul, part one

the 10 vowels · the 10 basic consonants · syllable blocks · your first real words · 30 min

Korean does not look like a language you can start reading today. It is.

Hangul has a birthday. Almost every writing system on earth drifted into existence over centuries; Hangul was designed on purpose, published in 1443, with a manual explaining the reasoning. The stated goal was that an ordinary person could learn it in a morning.

That is not marketing. The vowels are pictures of earth, sky and a person. The consonants are pictures of your mouth making the sound. Nothing here is arbitrary, which is why it goes in fast and stays.

★ By the end of Day 2 you will be able to read every Korean word you see. French learners cannot say that after thirty days. Two days, and the wall is gone.

1. The building blocks of every vowel

Three shapes. That is the entire vowel system.

Now combine them. The sun goes to one side of the person, or above and below the earth:

Add a second stroke, add a y

★ Ten vowels, and you learned four of them for free. The extra stroke means y, every single time, with no exceptions.

Two more you need immediately

⚠️ ㅐ and ㅔ sound identical in modern Korean. Native speakers do not distinguish them either; they just memorise which words take which. Do not spend a second on this.

2. The ten basic consonants — pictures of your mouth

This is the part that no other alphabet does. Five basic consonants are diagrams of the speech organ that makes them.

Put your tongue where ㄴ shows and say "n". It is exactly right. Say a hard "k" and feel the back of your tongue make the shape of ㄱ. This is not a mnemonic someone invented afterwards — it is how the letters were designed.

Then add a stroke for more force

★ The system is: shape = where in the mouth, strokes = how much force. Tomorrow you add one more stroke to get ㅋ ㅌ ㅍ ㅊ, and double the letter to get ㄲ ㄸ ㅃ ㅆ ㅉ. You are learning a system, not a list.

⚠️ Two consonants that are not what they look like

ㄹ: say the tt in American "butter", or the r in Spanish "pero". Korean has no separate r and l, which is why rice and lice are the same word for many Korean speakers — and why you must stop choosing between them.

⚠️ And four English sounds Korean does not have

f · v · z · th — none of them exist. Coffee becomes 커피 (keo-pi), video becomes 비디오 (bi-di-o). Do not look for them.

3. ★★ The three vowels that will trip you

Everything above is easy except these. Spend real time here — they are the difference between being understood and not.

① ㅓ vs ㅗ — the killer pair

⚠️ English writes both as "o" in romanisation systems you will see online, which is why learners merge them for years. They are completely different words:

★ The physical test: put a finger on your lips. If they push forward, you said ㅗ.For ㅓ they must not move at all.

② ㅡ (eu) — the one with no English equivalent

Say "oo". Now keep your tongue exactly where it is and pull your lips back into a wide smile. Do not let the tongue move. That flat, tight sound is ㅡ.

⚠️ It is not "you", not "uh", and not silent. It appears everywhere — 그 (that), 스 (s- in loanwords), 은/는 (the topic particle you meet on Day 5).

③ ㅡ vs ㅜ

Same tongue, opposite lips. 그 (geu, that) vs 구 (gu, nine).

4. ★★ Syllable blocks — the part that looks hard and is not

Korean does not write letters in a line. It packs each syllable into a square block.

### Every block = one syllable. Every block starts with a consonant.

Where the consonant goes depends on the vowel's shape

★ That is the whole rule. The block is always the same size, so a tall thin vowel sits beside the consonant and a wide flat vowel sits under it. It is a layout rule, not a grammar rule.

⚠️ And that is what ㅇ is for

Every block must begin with a consonant — so when a syllable starts with a vowel sound, you write ㅇ as a silent placeholder:

★ ㅇ at the front is a spacer, silent, doing nothing. English speakers try to pronounce it. Do not. (At the end of a block it becomes ng — that is tomorrow.)

5. Read these — you can already

Cover the romanisation and read the Korean. Say each one out loud three times.

★ You have been reading Korean for about twenty minutes. Not transliterating — reading. Nothing in that table needed romanisation once you knew the blocks.

⚠️ Now stop using romanisation. From tomorrow it actively slows you down: it hides ㅓ/ㅗ, it invents an r/l choice that does not exist, and it makes your eyes skip the Hangul. This course keeps romanisation for the first week only, and then drops it.

6. Exercises

A. Read aloud and give the sound.

1. 가 2. 고 3. 나 4. 누 5. 미 6. 무 7. 서 8. 소

B. ⚠️ ㅓ or ㅗ? Read the pair, then say which is which.

1. 어 / 오 2. 서 / 소 3. 머 / 모 4. 저 / 조

C. ⚠️ ㅡ or ㅜ?

1. 그 / 구 2. 느 / 누 3. 스 / 수

D. Build the block.

1. ㄱ + ㅏ 2. ㅁ + ㅗ 3. ㅅ + ㅣ 4. ㄷ + ㅜ 5. ㅎ + ㅏ 6. ㅈ + ㅡ

E. Where does the consonant go — left or top?

1. ㅏ 2. ㅗ 3. ㅣ 4. ㅜ 5. ㅓ 6. ㅡ

F. Read the word, then give the meaning.

1. 우유 2. 나무 3. 어머니 4. 바다 5. 지도 6. 아이

G. Write it in Hangul.

1. a-i 2. na-bi 3. o-ri 4. ga-su 5. da-ri

7. Today's 10 sentences (flashcards)

⚠️ These use letters you meet tomorrow — the ones sitting at the bottom of a block. Learn them today as sound; by tomorrow evening you will be able to read every one.

1. 안녕하세요. — Hello (an-nyeong-ha-se-yo)
2. 감사합니다. — Thank you (gam-sa-ham-ni-da)
3. 네. / 아니요. — Yes. / No. (ne / a-ni-yo)
4. 죄송합니다. — I'm sorry (joe-song-ham-ni-da)
5. 저기요. — Excuse me (jeo-gi-yo)
6. 잠시만요. — Just a moment (jam-si-man-yo)
7. 몰라요. — I don't know (mol-la-yo)
8. 한국어 조금 해요. — I speak a little Korean (han-gu-geo jo-geum hae-yo)
9. 다시 말해 주세요. — Please say that again (da-si mal-hae ju-se-yo)
10. 안녕히 가세요. — Goodbye (an-nyeong-hi ga-se-yo)

★ 안녕하세요 and 몰라요 are the two to have ready by tonight. The first opens every interaction; the second is what keeps a conversation alive when you are lost.

8. 📲 Upload to LangNote

Screenshot or copy sections 1, 2 and 5, plus section 7 → set the study language to Korean.

★ Screenshot your Day 1 pronunciation score. You read these same sentences again on Day 30, and the two numbers side by side are the point of the whole challenge.

⚠️ Tomorrow finishes the alphabet — the bottom of the block (받침), the tense and aspirated consonants, and the handful of sound-change rules. Day 2 is the day you stop needing romanisation forever. Do not skip it and do not split it across two days.

langNote is a paid subscription and this course recommends it. The 30 lessons are free and complete either way.
