Hangul syllable 쵦

It is a syllable, not a translation. The block combines initial ㅊ, vowel ㅚ, and final consonant cluster ㄻ. Hangul letters like these are called jamo; together they describe how the syllable is built. In a Korean word, that word supplies its meaning.

Why does Hangul use syllable blocks?

Hangul groups letters into blocks that represent spoken syllables. Hangul is the Korean writing system. It was completed in 1443 and published with an explanatory guide in 1446. Unicode systematically encodes every modern initial–vowel–final combination, including this one.

The vowel ㅚ has a history of its own. In the 15th century it was pronounced as two vowel sounds; by the late 19th century it had shifted toward a rounded vowel. Modern standard Korean also allows a short, smooth transition into the vowel. This describes the vowel’s pronunciation, not the age of the whole syllable.

Older Korean may spell a syllable with a sequence of jamo even when modern Hangul has no single precomposed block for it. Unicode’s inclusion of a modern combination does not prove that the same syllable was used as a word in historical Korean.

How do you type 쵦?

Enter its three jamo in a Korean input method. Enter ㅊ, then ㅚ, then ㄻ; the input method composes them into 쵦. Keep the jamo together: another character, including a combining mark, between them prevents Unicode from composing the block.

If older Korean software cannot display it, the system may support only a limited Hangul repertoire. That does not make the syllable malformed.
