Hangul syllable Ddyuh

Its role comes from the Korean spelling around it.

뜧 is one Korean syllable block. Its three letter parts are the initial consonant ᄄ, vowel ᅲ, and final consonant ᇂ; Korean calls these parts jamo. The surrounding spelling gives the block its place in a word.

How did Hangul blocks arise?

Hangul groups letters into square blocks, one for each syllable.

The National Hangeul Museum places the first mention of Hunminjeongeum, the script's original name, in the Sejong Sillok, the court annals of King Sejong, in the twelfth lunar month of 1443; its explanatory book appeared in 1446. The Joseon court created an alphabetic script to write Korean speech directly, which Chinese characters did not represent in the same way.

Hangul's letters, called jamo, are arranged into syllable blocks; this is why 뜧 has three parts in one block. Chinese characters called Hanja were also used to write Korean, but they are a separate writing tradition, not ingredients in this syllable. The script is called Hangul in South Korea and Chosŏn'gŭl in North Korea. In 2001, a terminology effort involving both Koreas used Jeongeum instead of Hangul for the script's name in the ISO character standard.

How do I type 뜧?

A Korean 2-set keyboard builds it from three jamo.

Switch your keyboard input to Korean, then press Shift+E, B, G. On the standard 2-set layout, those keys enter ㄸ, ㅠ, and ㅎ; the input method combines them as 뜧. Other layouts can map different keys, so check which Korean layout is active if this sequence fails.
