Hangul syllable Ddunh

Its name describes its build, not a Korean word. This Hangul syllable is made from jamo—letters that join inside a syllable block: ᄄ at the start, ᅮ as the vowel, and ᆭ as the final consonant cluster. Unicode forms the label “DDUNH” from their short names; it is an identifier, not a pronunciation guide.

Hangul was devised under King Sejong in 1443 and introduced in the 1446 book Hunminjeongeum, whose title means “Correct Sounds for Teaching the People.” The book explains how initial consonants, vowels, and final consonants combine into syllables. The alphabet made Korean easier for ordinary people to write than Chinese characters, which were difficult to learn and did not fit Korean's structure well.

This glyph is one precomposed Hangul character, though Unicode also gives it a canonical decomposition into three jamo. NFD normalization can turn the block into that letter sequence; NFC can compose the sequence back into one block.

How do I type 뚢 with a Korean keyboard?

On the Korean two-set keyboard, use Shift+E, N, S, G. With Korean input enabled, those keys enter ㄸ + ㅜ + ㄴ + ㅎ, which the input method joins into 뚢.

In an editor that supports Unicode-hex input, enter B6A2.
