Korean Syllable Blocks: 음절 구조

Read the lesson, then practise at your own pace. All explanations and examples are on this page.

Block Basics 블록 기초

What Is a Syllable Block? 음절이란?

Every Korean syllable is written inside an invisible square block. Unlike English where letters go left to right in a row, Korean stacks consonants and vowels together into compact, visually balanced blocks. Each block represents exactly one syllable — one unit of sound.

The Three Positions 세 가지 자리

Every Korean syllable block has three named positions. Two are required (initial consonant and medial vowel) and one is optional (the final consonant). Learning these positions by name is essential — Korean grammar references them constantly.

Four Syllable Block Patterns 네 가지 음절 패턴

Korean syllables follow four basic structural patterns depending on whether a final consonant (받침) is present and whether the syllable begins with a vowel or consonant.

PatternSyllablePiecesNote
CV가ㄱ + ㅏinitial + vowel
V아ㅇ + ㅏsilent ㅇ + vowel
CVC간ㄱ + ㅏ + ㄴinitial + vowel + 받침
VC안ㅇ + ㅏ + ㄴsilent ㅇ + vowel + 받침

Letters and sounds

LetterPronunciationExampleMeaningNote
한 ㅎ + ㅏ + ㄴhan한국KoreaEvery syllable is a square block — initial consonant, vowel, and optional final consonant.
국 ㄱ + ㅜ + ㄱguk한국KoreaThis block has all three positions: 초성 (ㄱ) + 중성 (ㅜ) + 받침 (ㄱ).
어 ㅇ + ㅓeo한국어Korean languageVowel-initial syllables use silent ㅇ as a placeholder. The ㅇ here makes no sound.

Check your understanding

How many vowels does a single Korean syllable block contain?

Answer

Exactly one

The INITIAL consonant position (first consonant) is called…

Answer

초성

When a syllable starts with a VOWEL sound, you write __ as a placeholder initial consonant.

Answer

ㅇ

Letters and sounds

LetterPronunciationExampleMeaningNote
가 ㄱ + ㅏga가다to goCV pattern — the simplest block type. Just an initial consonant and a vowel.
아 ㅇ + ㅏa아기babyV-only pattern — silent ㅇ in the initial position, vowel only sounds.
간 ㄱ + ㅏ + ㄴgan간liver / wentCVC pattern — initial consonant + vowel + final consonant (받침). Three parts.

Check your understanding

안 (inside / no) — what structural pattern is this?

Answer

VC (silent ㅇ + vowel + final)

Vowel Shapes 모음 방향

Vertical vs Horizontal Vowels 세로 vs 가로 모음

The shape of the vowel determines where the initial consonant goes inside the block. Tall, vertical vowels push the consonant to the left; wide, horizontal vowels push it to the top. This is what gives Korean its distinctive square appearance.

Letters and sounds

LetterPronunciationExampleMeaningNote
가 ㄱ ← ㅏgaㅏ is a TALL vertical vowel. The initial consonant sits to its LEFT.
너 ㄴ ← ㅓneo너you (informal)ㅓ is also a tall vertical vowel — consonant LEFT, vowel RIGHT.
시 ㅅ ← ㅣsi시간timeㅣ is the tallest vowel. Consonant always goes to its left.
고 ㄱ ↑ ㅗgo고마워thank youㅗ is a WIDE horizontal vowel. The initial consonant sits ON TOP of the vowel.
누 ㄴ ↑ ㅜnu누구whoㅜ is a wide horizontal vowel — consonant on top, vowel below. The line points DOWN.
그 ㄱ ↑ ㅡgeu그리고andㅡ is a flat horizontal vowel — the consonant sits above it.

Check your understanding

With a TALL vowel like ㅏ, ㅓ, or ㅣ — where does the initial consonant go?

With a WIDE vowel like ㅗ, ㅜ, or ㅡ — where does the initial consonant go?

Answer

On top

배 (stomach / ship) contains ㅐ — which type of vowel is ㅐ?

Answer

Tall vertical

Which of these is a WIDE (horizontal) vowel?

Now let's practice building simple CV syllables — consonant + vowel, no batchim. These are the easiest blocks to read and write. Listen to each one and try to produce the sound yourself.

Building syllables

PiecesSyllableMeaning
ㅂ + ㅏ바ba — 바나나 (banana)
ㄴ + ㅏ나na — 나 (I / me)
ㅅ + ㅏ사sa — 사랑 (love)
ㅎ + ㅏ하ha — 하늘 (sky)
ㄱ + ㅗ고go — 고마워 (thank you, informal)
ㄴ + ㅜ누nu — 누구 (who)
ㅁ + ㅣ미mi — 미래 (future)
ㄱ + ㅣ기gi — 기다리다 (to wait)

Batchim 받침

Adding Batchim — The Final Consonant 받침 추가

When you add a consonant at the bottom of a block, that consonant becomes the 받침 (batchim) — the final consonant. Batchim is what gives many Korean words their rich, resonant endings. Watch how adding batchim transforms simple syllables into real words.

Letters and sounds

LetterPronunciationExampleMeaningNote
산 ㅅ + ㅏ + ㄴsan산mountainㄴ is the 받침 here — it sits at the bottom of the block below ㅅ and ㅏ.
달 ㄷ + ㅏ + ㄹdal달moon / monthㄹ 받침 — tongue taps the roof of your mouth lightly to produce the ending.
밥 ㅂ + ㅏ + ㅂbap밥rice / mealㅂ받침 — lips close at the end without releasing. The 'p' is unreleased.
봄 ㅂ + ㅗ + ㅁbom봄spring (season)ㅁ 받침 — lips close gently at the end. A nasal resonant ending.
길 ㄱ + ㅣ + ㄹgil길road / wayㄹ 받침 again — the tongue lingers against the palate. Sounds like a soft 'l'.

Practice & Summary 연습

Congratulations — you have learned the core structure of Korean syllable blocks! Here is a quick summary of the five rules that govern every syllable in the Korean writing system.

  • Every block has exactly one vowel (중성 / Jungseong)
  • Vowel-initial syllables use silent ㅇ as a placeholder initial consonant
  • Tall vowels (ㅏ, ㅓ, ㅣ) — initial consonant sits to the left, vowel to the right
  • Wide vowels (ㅗ, ㅜ, ㅡ) — initial consonant sits on top, vowel below
  • Optional 받침 (batchim) sits at the bottom of the block, below everything else
