Modular Hangul letter pieces combining into a Korean syllable block.

Syllable Blocks

음절 Eum-jeol. Learn how Korean letters stack into syllable blocks.

English writes letters in a line. Korean stacks letters (자모 jamo) into square blocks. Each block represents one syllable. The word 한국어 has three blocks: 한, 국, 어. It has three syllables: han · guk · eo.

The Three Positions

Every syllable block has up to three layers: two required, one optional.

초성Initial consonant

Always comes first. Every syllable starts with one. If there's no consonant sound, use ㅇ as a placeholder.

ㄱ ㄴ ㄷ ㄹ…
중성Vowel

Sits next to or below the initial consonant. Determines the block shape: vertical vowels sit to the right; horizontal vowels sit below.

ㅏ ㅓ ㅗ ㅜ…
종성Final consonant

Optional. Known as 받침 (batchim). Sits at the bottom of the block. About half of all Korean syllables have one.

ㄴ ㄹ ㅁ ㄱ…

Two Block Shapes

The vowel's orientation determines how the block is arranged. The consonant grows to fill the space.

ㄱ
ㅏ
가
ㄱ + ㅏ

ㅗ
고
ㄱ + ㅗ
ㅎ
ㅏ
ㄴ
한
ㅎ + ㅏ + ㄴ
ㄱ
ㅜ

국

Vertical vowels: side by side

ㅏ ㅑ ㅓ ㅕ ㅣ ㅐ ㅒ ㅔ ㅖ and their compounds: consonant left, vowel right

Horizontal vowels: stacked

ㅗ ㅛ ㅜ ㅠ ㅡ and their compounds: consonant above, vowel below
