In Section 1, you learned that Korean letters are not normally written in a straight line. Instead, they are grouped into compact syllable blocks.
Now we will study the most basic and important syllable structure:
Consonant + Vowel
or:
C + V
In Korean terms:
초성 + 중성
This is the foundation for reading and building thousands of Korean syllables.
What Does C + V Mean?
C means consonant.
V means vowel.
So:
C + V = Consonant + Vowel
For example:
ㄱ + ㅏ → 가
Here:
Another example:
ㄴ + ㅗ → 노
And:
ㅁ + ㅜ → 무
Each result is one complete Korean syllable.
Korean Terms: 초성 + 중성
In a Korean syllable:
초성
The consonant that begins the syllable.
중성
The vowel inside the syllable.
For example:
나
ㄴ = 초성
ㅏ = 중성
There is no final consonant.
So the structure is:
초성 + 중성
The Simplest Korean Syllable
A basic syllable requires:
one initial consonant + one vowel
For example:
Initial | Vowel | Syllable |
|---|
ㄱ | ㅏ | 가 |
ㄴ | ㅏ | 나 |
ㄷ | ㅏ | 다 |
ㄹ | ㅏ | 라 |
ㅁ | ㅏ | 마 |
Notice that all five syllables use the same vowel:
ㅏ
Only the initial consonant changes.
Why Letter Position Changes
The shape of the vowel determines how the syllable is arranged.
There are two main beginner layouts:
Layout A — Left + Right
Used mainly with vertical vowels.
Example:
ㄱ + ㅏ → 가
Layout B — Top + Bottom
Used mainly with horizontal vowels.
Example:
ㄱ + ㅗ → 고
The pronunciation order stays:
consonant first → vowel second
even though their visual positions change.
C + V with Vertical Vowels
Vertical vowels usually occupy the right side of the syllable.
The consonant is placed on the left.
Think of the block like this:
For example:
ㄱ + ㅏ → 가
ㄴ + ㅓ → 너
ㅁ + ㅣ → 미
Common Vertical Vowels
The main vertical-style vowels include:
ㅏ ㅑ ㅓ ㅕ ㅣ
and also:
ㅐ ㅒ ㅔ ㅖ
Some complex vowels also use a mainly vertical structure, which we will apply later.
Examples with ㅏ
Combine ㅏ with different consonants:
Letters | Syllable | Romanization |
|---|
ㄱ + ㅏ | 가 | ga |
ㄴ + ㅏ | 나 | na |
ㄷ + ㅏ | 다 | da |
ㄹ + ㅏ | 라 | ra |
ㅁ + ㅏ | 마 | ma |
ㅂ + ㅏ | 바 | ba |
ㅅ + ㅏ | 사 | sa |
ㅇ + ㅏ | 아 | a |
ㅈ + ㅏ | 자 | ja |
ㅊ + ㅏ | 차 | cha |
ㅋ + ㅏ | 카 | ka |
ㅌ + ㅏ | 타 | ta |
ㅍ + ㅏ | 파 | pa |
ㅎ + ㅏ | 하 | ha |
This is one of the best beginner reading drills.
Examples with ㅓ
Now keep the consonants similar but change the vowel to:
ㅓ
Letters | Syllable |
|---|
ㄱ + ㅓ | 거 |
ㄴ + ㅓ | 너 |
ㄷ + ㅓ | 더 |
ㄹ + ㅓ | 러 |
ㅁ + ㅓ | 머 |
ㅂ + ㅓ | 버 |
ㅅ + ㅓ | 서 |
ㅇ + ㅓ | 어 |
ㅈ + ㅓ | 저 |
ㅊ + ㅓ | 처 |
ㅋ + ㅓ | 커 |
ㅌ + ㅓ | 터 |
ㅍ + ㅓ | 퍼 |
ㅎ + ㅓ | 허 |
Examples with ㅣ
Now combine consonants with:
ㅣ
Letters | Syllable |
|---|
ㄱ + ㅣ | 기 |
ㄴ + ㅣ | 니 |
ㄷ + ㅣ | 디 |
ㄹ + ㅣ | 리 |
ㅁ + ㅣ | 미 |
ㅂ + ㅣ | 비 |
ㅅ + ㅣ | 시 |
ㅇ + ㅣ | 이 |
ㅈ + ㅣ | 지 |
ㅊ + ㅣ | 치 |
ㅋ + ㅣ | 키 |
ㅌ + ㅣ | 티 |
ㅍ + ㅣ | 피 |
ㅎ + ㅣ | 히 |
Vertical Layout Practice
Notice the common structure:
가
ㄱ occupies the left part.
ㅏ occupies the right part.
Likewise:
너
ㄴ → left
ㅓ → right
미
ㅁ → left
ㅣ → right
This basic arrangement remains consistent.
C + V with Horizontal Vowels
Horizontal vowels behave differently.
The consonant is placed at the top.
The vowel is placed below it.
Imagine:
C
V
For example:
ㄱ + ㅗ → 고
and:
ㄴ + ㅜ → 누
Common Horizontal Vowels
The main horizontal-style vowels are:
ㅗ ㅛ ㅜ ㅠ ㅡ
Examples:
고
교
구
규
그
Examples with ㅗ
Letters | Syllable |
|---|
ㄱ + ㅗ | 고 |
ㄴ + ㅗ | 노 |
ㄷ + ㅗ | 도 |
ㄹ + ㅗ | 로 |
ㅁ + ㅗ | 모 |
ㅂ + ㅗ | 보 |
ㅅ + ㅗ | 소 |
ㅇ + ㅗ | 오 |
ㅈ + ㅗ | 조 |
ㅊ + ㅗ | 초 |
ㅋ + ㅗ | 코 |
ㅌ + ㅗ | 토 |
ㅍ + ㅗ | 포 |
ㅎ + ㅗ | 호 |
Examples with ㅜ
Letters | Syllable |
|---|
ㄱ + ㅜ | 구 |
ㄴ + ㅜ | 누 |
ㄷ + ㅜ | 두 |
ㄹ + ㅜ | 루 |
ㅁ + ㅜ | 무 |
ㅂ + ㅜ | 부 |
ㅅ + ㅜ | 수 |
ㅇ + ㅜ | 우 |
ㅈ + ㅜ | 주 |
ㅊ + ㅜ | 추 |
ㅋ + ㅜ | 쿠 |
ㅌ + ㅜ | 투 |
ㅍ + ㅜ | 푸 |
ㅎ + ㅜ | 후 |
Examples with ㅡ
Letters | Syllable |
|---|
ㄱ + ㅡ | 그 |
ㄴ + ㅡ | 느 |
ㄷ + ㅡ | 드 |
ㄹ + ㅡ | 르 |
ㅁ + ㅡ | 므 |
ㅂ + ㅡ | 브 |
ㅅ + ㅡ | 스 |
ㅇ + ㅡ | 으 |
ㅈ + ㅡ | 즈 |
ㅊ + ㅡ | 츠 |
ㅋ + ㅡ | 크 |
ㅌ + ㅡ | 트 |
ㅍ + ㅡ | 프 |
ㅎ + ㅡ | 흐 |
Compare Vertical and Horizontal Vowels
Use the same consonant:
ㄱ
With vertical vowels:
가
거
기
With horizontal vowels:
고
구
그
So:
ㄱ + ㅏ → 가
but:
ㄱ + ㅗ → 고
The difference is not only pronunciation.
The internal shape of the syllable block also changes.
Important Reading Direction
Regardless of the visual shape, read the consonant first.
For:
가
Read:
ㄱ → ㅏ
For:
고
Read:
ㄱ → ㅗ
Do not read according to physical left-to-right or top-to-bottom alone.
Instead, understand the structural order:
초성 → 중성
C + V with ㅇ
A syllable cannot visually begin with a vowel alone.
Therefore, when a vowel is pronounced without an initial consonant sound, Korean places:
ㅇ
in the initial position.
Remember:
Initial ㅇ is silent.
Examples:
ㅇ + ㅏ → 아
ㅇ + ㅓ → 어
ㅇ + ㅗ → 오
ㅇ + ㅜ → 우
ㅇ + ㅡ → 으
ㅇ + ㅣ → 이
The ㅇ simply allows the vowel to form a valid syllable block.
Comparing ㅇ + V Syllables
Letters | Result | Approximate sound |
|---|
ㅇ + ㅏ | 아 | a |
ㅇ + ㅑ | 야 | ya |
ㅇ + ㅓ | 어 | eo |
ㅇ + ㅕ | 여 | yeo |
ㅇ + ㅗ | 오 | o |
ㅇ + ㅛ | 요 | yo |
ㅇ + ㅜ | 우 | u |
ㅇ + ㅠ | 유 | yu |
ㅇ + ㅡ | 으 | eu |
ㅇ + ㅣ | 이 | i |
These syllables appear constantly in Korean words.
C + V with Y-Vowels
The same C + V rule works with:
ㅑ ㅕ ㅛ ㅠ
Examples:
ㄱ + ㅑ → 갸
ㄴ + ㅕ → 녀
ㅁ + ㅛ → 묘
ㅇ + ㅠ → 유
Notice their positions:
ㅑ and ㅕ are vertical-style vowels.
ㅛ and ㅠ are horizontal-style vowels.
Examples with ㅑ
Combination | Result |
|---|
ㄱ + ㅑ | 갸 |
ㄴ + ㅑ | 냐 |
ㄷ + ㅑ | 댜 |
ㄹ + ㅑ | 랴 |
ㅁ + ㅑ | 먀 |
ㅂ + ㅑ | 뱌 |
ㅅ + ㅑ | 샤 |
ㅇ + ㅑ | 야 |
ㅈ + ㅑ | 쟈 |
ㅊ + ㅑ | 챠 |
ㅋ + ㅑ | 캬 |
ㅌ + ㅑ | 탸 |
ㅍ + ㅑ | 퍄 |
ㅎ + ㅑ | 햐 |
Not all possible combinations are equally common in everyday Korean, but understanding the construction rule is important.
Examples with ㅕ
겨 녀 뎌 려 며 벼 셔 여 져 쳐 켜 텨 펴 혀
Notice:
ㄴ + ㅕ → 녀
ㅁ + ㅕ → 며
ㅇ + ㅕ → 여
ㅎ + ㅕ → 혀
Examples with ㅛ
교 뇨 됴 료 묘 뵤 쇼 요 죠 쵸 쿄 툐 표 효
Some combinations are uncommon as independent syllables, but this drill helps learners understand the structure.
Common examples include:
요
교
표
효
Examples with ㅠ
규 뉴 듀 류 뮤 뷰 슈 유 쥬 츄 큐 튜 퓨 휴
Many of these appear frequently in modern loanwords.
Examples:
뉴 — as in 뉴욕, New York
뷰 — view
슈 — often used in loanwords
큐 — cue / Q
퓨 — appears in loanword syllables
휴 — appears in native Korean words too
Combining Double Consonants
The C + V pattern also works with tense consonants:
ㄲ ㄸ ㅃ ㅆ ㅉ
Examples:
Letters | Syllable |
|---|
ㄲ + ㅏ | 까 |
ㄸ + ㅏ | 따 |
ㅃ + ㅏ | 빠 |
ㅆ + ㅏ | 싸 |
ㅉ + ㅏ | 짜 |
More examples:
꺼
또
뿌
쓰
찌
The syllable-building principle remains exactly the same.
Aspirated Consonants
Aspirated consonants also combine normally:
ㅋ ㅌ ㅍ ㅊ
Examples:
ㅋ + ㅏ → 카
ㅌ + ㅗ → 토
ㅍ + ㅜ → 푸
ㅊ + ㅣ → 치
This shows that once you understand C + V positioning, you can apply it to essentially every initial consonant.
