Course: Learn Korean from Zero to Practical Korean
Lesson: 008 — Build Korean Blocks with Consonants and Vowels
Module: Hangul Foundation
Level: Absolute beginner
Focus: building simple Korean syllable blocks from consonants and vowels
Listening support: four confirmed block-building audio clips for listen-and-repeat practice
Today’s practice result: build and read open blocks like 가, 거, 고, 구, 기
Saved task: a personal 15-block reading grid and block-builder note
In the last three lessons, you learned the basic Korean vowel blocks and all fourteen basic consonants. In this lesson, you will use those pieces to build simple Korean syllable blocks, the basic reading unit of Hangul.
This is not about memorizing a huge chart. It is about learning the simple building pattern behind Korean writing: choose a beginning consonant, choose a vowel, combine them into one block, and read the finished block as one sound.
By the end of this lesson, you should be able to look at two Hangul parts such as ㄱ + ㅏ and understand why they become the finished block 가.
• Build simple Korean blocks from a consonant and a vowel.
• Tell whether the vowel goes to the right side or below the consonant.
• Read open blocks such as 가, 너, 모, 수, 지, 하.
• Understand why ㄱ + ㅏ becomes 가, but ㅇ + ㅏ becomes 아.
• Understand that Korean has 21 vowel letters and 19 consonant letters, even though this lesson starts with a smaller practice set.
• Use audio practice to connect the table pattern with real block reading.
R1. What is the consonant ㅇ called?
Show answer
It is called 이응 (ieung).
R2. Is ㅇ + ㅏ read as 이응아?
Show answer
No. ㅇ + ㅏ becomes 아. The beginning ㅇ is silent here.
R3. How do you read ㅈ + ㅏ as a finished block?
Show answer
자. The consonant is called 지읒, but the finished block is read 자.
Follow the lesson from full Hangul map awareness to block-building, listening, practice, and saved output.
1. Read the idea first: consonant + vowel → finished block.
2. Use the tables to see the pattern visually.
3. Use the audio cards to listen one row at a time and repeat slowly.
4. Cover the romanization after a few rounds and read only the Korean blocks.
5. Finish with the Practice Drill and Quick Check before saving your output.
▲ Separate Korean consonants and vowels combine into one readable Hangul syllable block.
🧭 Where the Full 21 Vowels and 19 Consonants Fit
Modern Hangul has a full letter set that is bigger than what we will use in today’s main table. Korean has 21 vowel letters and 19 consonant letters when the full modern set is counted.
This lesson does not try to use all 21 vowels and all 19 consonants at once. That would create a giant chart before you have enough reading confidence.
Today, we use the letters you already know to learn the block-building pattern first. The remaining vowel groups and tense consonants will appear soon, before we move into final consonants and real-word reading.
| Group | Letters | Course timing |
|---|---|---|
| Basic vowels | ㅏ ㅑ ㅓ ㅕ ㅗ ㅛ ㅜ ㅠ ㅡ ㅣ | Already introduced in Lesson 005. Lesson 008 uses them carefully, with five anchor vowels in the main table. |
| Additional simple vowels | ㅐ ㅒ ㅔ ㅖ | Coming next as confusing vowel pairs. |
| Compound vowels | ㅘ ㅙ ㅚ ㅝ ㅞ ㅟ ㅢ | Coming soon after the confusing vowel pairs. |
| Basic consonants | ㄱ ㄴ ㄷ ㄹ ㅁ ㅂ ㅅ ㅇ ㅈ ㅊ ㅋ ㅌ ㅍ ㅎ | Already introduced in Lessons 006 and 007. |
| Tense consonants | ㄲ ㄸ ㅃ ㅆ ㅉ | Coming soon, for recognition-level practice before detailed sound comparison. |
🧩 The Block-Building Idea
Korean is written in syllable blocks. A simple open block usually has two main parts:
Beginning consonant + vowel = one finished block
ㄱ + ㅏ = 가
ㄴ + ㅓ = 너
ㅁ + ㅗ = 모
Notice what changes: the letters do not stay separate like ㄱㅏ. They combine into one block: 가.
Today, we are not studying final consonants, also called batchim. Blocks like 한, 물, 국, 집 have a final sound at the bottom. That comes later. For now, practice open blocks with only a beginning consonant and a vowel.
🔤 Two Simple Open-Block Layouts
Beginners often wonder why some vowels appear on the right side of a consonant while others appear below it. The easiest beginner rule is visual: tall vowels usually go to the right, and wide vowels usually go below.
| Layout | Vowel group | Example | Finished block |
|---|---|---|---|
| Right side | ㅏ ㅑ ㅓ ㅕ ㅣ | ㄱ + ㅏ | 가 |
| Below | ㅗ ㅛ ㅜ ㅠ ㅡ | ㄱ + ㅗ | 고 |
This is a reading lesson, not a handwriting or calligraphy lesson. Your goal is to recognize the layout and read the finished block.
➡️ Vowels That Go to the Right
The vowels ㅏ, ㅑ, ㅓ, ㅕ, ㅣ are usually placed on the right side of the beginning consonant in a simple open block.
ㄱ + ㅏ = 가
ㄱ + ㅑ = 갸
ㄱ + ㅓ = 거
ㄱ + ㅕ = 겨
ㄱ + ㅣ = 기
⬇️ Vowels That Go Below
The vowels ㅗ, ㅛ, ㅜ, ㅠ, ㅡ are usually placed below the beginning consonant in a simple open block.
ㄱ + ㅗ = 고
ㄱ + ㅛ = 교
ㄱ + ㅜ = 구
ㄱ + ㅠ = 규
ㄱ + ㅡ = 그
▲ Right-side vowels sit beside the consonant, while below vowels sit under it in simple open blocks.
⭕ What Happens with Silent ㅇ?
Korean blocks need a beginning position. When a block starts with a vowel sound, Korean uses ㅇ in the beginning position. In this position, ㅇ is silent.
ㅇ + ㅏ = 아
ㅇ + ㅓ = 어
ㅇ + ㅗ = 오
ㅇ + ㅜ = 우
ㅇ + ㅣ = 이
ㅇ is called 이응 when you name the consonant. But inside the finished block 아, the beginning ㅇ is silent. So you read the block as 아, not 이응아.
📘 Block Builder Table
Now use five anchor vowels to build a practical reading grid: ㅏ, ㅓ, ㅗ, ㅜ, ㅣ. These five keep the table readable while still showing the main block-building pattern clearly.
| Start | ㅏ | ㅓ | ㅗ | ㅜ | ㅣ |
|---|---|---|---|---|---|
| ㅇ | 아 | 어 | 오 | 우 | 이 |
| ㄱ | 가 | 거 | 고 | 구 | 기 |
| ㄴ | 나 | 너 | 노 | 누 | 니 |
| ㄷ | 다 | 더 | 도 | 두 | 디 |
| ㅁ | 마 | 머 | 모 | 무 | 미 |
| ㅅ | 사 | 서 | 소 | 수 | 시 |
| ㅈ | 자 | 저 | 조 | 주 | 지 |
| ㅎ | 하 | 허 | 호 | 후 | 히 |
This table is for reading practice. You do not need to memorize every block as a word. Focus on recognizing the pattern and reading each finished block smoothly.
1. Pick a starting consonant from the left column.
2. Pick a vowel from the top row.
3. Read the finished block where the row and column meet.
Example: ㄴ row + ㅜ column = 누.
You also learned ㅑ, ㅕ, ㅛ, ㅠ, ㅡ in Lesson 005. Here is a small preview using ㄱ so you can see that the same block-building logic continues:
ㄱ + ㅑ = 갸
ㄱ + ㅕ = 겨
ㄱ + ㅛ = 교
ㄱ + ㅠ = 규
ㄱ + ㅡ = 그
Do not worry if these feel less familiar. The goal is to notice the pattern, not to master every sound today.
🔊 Listen & Repeat: Open Block Builder
Now listen to the same block-building pattern. Do not try to memorize every block at once. Listen one row at a time, then repeat slowly.
The main table shows a smaller set so the page stays readable. The audio stretches the same pattern across all 14 basic consonants you learned in Lessons 006 and 007, including some rows not shown in today’s table.
Listen in this order: Audio 1 → Pass 1 → Audio 2 → Pass 2 → Audio 3 → Pass 3 → Audio 4 → Pass 4.
These clips are for reading finished Korean blocks. They are not vocabulary practice and not consonant-name practice.
🇰🇷 Korean: 아 · 어 · 오 · 우 · 이 / 가 · 거 · 고 · 구 · 기 / 나 · 너 · 노 · 누 · 니
🔊 Reading: a · eo · o · u · i / ga · geo · go · gu · gi / na · neo · no · nu · ni
💬 Practice focus: silent ㅇ row, ㄱ row, and ㄴ row
🌿 Listening note: Hear how the same five vowels sound different with each beginning consonant.
아 어 오 우 이
가 거 고 구 기
나 너 노 누 니 Read one row at a time. Then cover the romanization.
🇰🇷 Korean: 다 · 더 · 도 · 두 · 디 / 라 · 러 · 로 · 루 · 리 / 마 · 머 · 모 · 무 · 미 / 바 · 버 · 보 · 부 · 비 / 사 · 서 · 소 · 수 · 시
🔊 Reading: da · deo · do · du · di / ra · reo · ro · ru · ri / ma · meo · mo · mu · mi / ba · beo · bo · bu · bi / sa · seo · so · su · si
💬 Practice focus: middle consonant rows from Lesson 006
🌿 Listening note: Keep the vowel rhythm steady while the beginning consonant changes.
다 더 도 두 디
라 러 로 루 리
마 머 모 무 미
바 버 보 부 비
사 서 소 수 시 Read slowly. Do not turn this into speed practice.
🇰🇷 Korean: 자 · 저 · 조 · 주 · 지 / 차 · 처 · 초 · 추 · 치 / 카 · 커 · 코 · 쿠 · 키 / 타 · 터 · 토 · 투 · 티 / 파 · 퍼 · 포 · 푸 · 피 / 하 · 허 · 호 · 후 · 히
🔊 Reading: ja · jeo · jo · ju · ji / cha · cheo · cho · chu · chi / ka · keo · ko · ku · ki / ta · teo · to · tu · ti / pa · peo · po · pu · pi / ha · heo · ho · hu · hi
💬 Practice focus: consonant rows from Lesson 007
🌿 Listening note: Notice the stronger air in ㅊ, ㅋ, ㅌ, and ㅍ. You do not need to analyze the pronunciation rules today.
자 저 조 주 지
차 처 초 추 치
카 커 코 쿠 키
타 터 토 투 티
파 퍼 포 푸 피
하 허 호 후 히 This is still block reading, not consonant-name practice.
🇰🇷 Korean: 갸 · 겨 · 교 · 규 · 그 / 냐 · 녀 · 뇨 · 뉴 · 느 / 먀 · 며 · 묘 · 뮤 · 므
🔊 Reading: gya · gyeo · gyo · gyu · geu / nya · nyeo · nyo · nyu · neu / mya · myeo · myo · myu · meu
💬 Practice focus: the other five basic vowels from Lesson 005
🌿 Listening note: Recognize that the same block-building rule also works with ㅑ, ㅕ, ㅛ, ㅠ, and ㅡ.
갸 겨 교 규 그
냐 녀 뇨 뉴 느
먀 며 묘 뮤 므 This is an extension, not the main table to memorize today.
These are reading sounds, not new vocabulary words. Your goal is to recognize the finished block and say it smoothly.

🧩 Quick Check
Try answering first, then open each card to check your understanding.
Q1. How many vowel letters are in the full modern Hangul vowel set?
01 Show answer
21. Today, we are not using all 21 at once. We are learning the block-building pattern first.
Q2. How many consonant letters are in the full modern Hangul consonant set?
02 Show answer
19. You already learned the 14 basic consonants, and tense consonants come soon.
Q3. Which vowel usually goes to the right side of the consonant: ㅏ or ㅗ?
03 Show answer
ㅏ usually goes to the right side: ㄱ + ㅏ = 가.
Q4. Why does 아 use ㅇ?
04 Show answer
A Korean block needs a beginning position. If there is no beginning consonant sound, silent ㅇ fills that position.
Q5. Is this lesson the full 21-vowel × 19-consonant map?
05 Show answer
No. This lesson teaches the block-building pattern first. The remaining vowel groups and tense consonants come soon.

🔁 Course Flow Preview
The next Hangul lessons will complete the missing pieces step by step:
• Lesson 009: Confusing Korean vowels — 애, 얘, 에, 예
• Lesson 010: Compound Korean vowels — 와, 왜, 외, 워, 웨, 위, 의
• Lesson 011: Full Korean vowel map — all 21 vowels together
• Lesson 012: Tense Korean consonants — ㄲ, ㄸ, ㅃ, ㅆ, ㅉ
After that, we can move more confidently into final consonants, batchim, and real Korean word reading.
💡 Final Thought
Reading Korean becomes much less mysterious when you see the block as a small system. You are not memorizing random shapes. You are combining known parts.
A simple Korean block is built by combining a beginning consonant and a vowel into one readable shape.

💬 Your Turn
Can you look at these three blocks and read them out loud without romanization?
가 · 노 · 히
If they feel easy, try one more row from today’s table. If they still feel slow, go back to Audio 1 and repeat the first three rows once more.
