Hangul Jongseong Phieuph-Thieuth

It is a compound consonant for a Hangul syllable's final slot.

Its name joins two Korean consonant names. Jongseong means the final position within a syllable; ퟻ is one encoded jamo for that slot, so it belongs inside a historical spelling rather than standing as a word.

Why was this final cluster written?

It records a consonant sequence at the end of a syllable.

Old Hangul final consonant clusters record sequences that sit at a syllable's end. The 1446 Hunminjeongeum, a guide explaining the Korean writing system, describes syllables as initial consonant, vowel, and final consonant, and reuses initial consonants in the final position. Later spelling usually favored eight final consonants, while early records also include others such as ㅌ and ㅍ. ퟻ belongs to that wider system.

A Korean proposal to encode Old Hangul, submitted in 2006, identifies ퟻ as HX355 and cites examples from older documents and later grammar books. It places the character in documented Old Hangul spelling, not modern conversational writing.

How do I type or display ퟻ?

Use an Old Hangul input method and a font with archaic support.

Microsoft's Korean input-method guide distinguishes the standard Korean input method from Microsoft Old Hangul, which supports jamo no longer used in modern Hangul. The guide was updated June 20, 2024. For historical text, choose Old Hangul rather than the standard mode.

ퟻ is a conjoining final jamo, designed to join the syllable's initial and vowel. As of 2026, support for archaic Hangul glyphs and shaping still varies by font and text engine; a box or detached mark is a display problem, not a different character.
