Hangul syllable 훒

It is a Hangul syllable block, read inside its Korean word.

It combines initial ㅎ, vowel ㅜ and final cluster ㄿ, called a double final consonant cluster (겹받침). These parts show the syllable’s spelling and help determine its sound; the whole Korean word gives the meaning.

Hangeul was designed to make Korean easier to write and learn than Chinese-character writing and idu, an older system that used Chinese characters for Korean words and grammar. A royal document called Hunminjeongeum presents the alphabet in 1443; its explanatory book appeared in 1446. In Korean texts from pre-1933, jamo may appear separately rather than as modern precomposed blocks, so older material can show related components without containing this exact block.

How is ㄿ pronounced in a Korean word?

Its sound changes with the word around it.

In 읊다, a Korean verb meaning “to recite,” final ㄿ is heard as a p-like stop; the following ㄷ is pronounced as a tense t. Korean writes this standard pronunciation as 읍따. That sound change belongs to 읊다; it does not make 훒 mean “to recite.”

Why does 훒 split into jamo?

It is another Unicode representation of the same syllable.

A Korean input method editor (IME) assembles jamo as you type. Software can also represent 훒 as one precomposed block or as the three conjoining jamo 훒. NFC normalization selects the block; NFD exposes the jamo sequence. That changes the text representation, not the intended Korean spelling.
