Hangul syllable Dwan

It is a Hangul syllable, not a sign with one fixed meaning.

Read roughly “dwan”: ㄷ gives the starting consonant, ㅘ the vowel, and ㄴ the ending consonant. It contributes a syllable’s sound inside a Korean word or name; the rest of the spelling gives the meaning.

Hangul was created to write Korean speech. Its creation was recorded in 1443, and the explanatory guide Hunminjeongeum was published in 1446. The system joins Korean letters into syllable blocks and was designed around Korean rather than Chinese writing.

Why does 돤 represent a Mandarin syllable?

It is a Korean spelling for a sound, not a Korean definition. As of 2026, a National Institute of Korean Language table maps the Mandarin syllable written duan in pinyin (roughly “twan”) to 돤. In the 1448 Dongguk Jeongun, a Korean pronunciation guide for Chinese characters, 돤 appears as a pronunciation value for characters including 端 and 斷. The block records pronunciation; the surrounding text supplies meaning.

Hangul letters, called jamo, combine to form the block: ㄷ, ㅘ, and ㄴ make 돤. The vowel ㅘ itself combines ㅗ and ㅏ. Unicode text can represent the syllable as one precomposed block or as its separate letters; normalization can convert between these equivalent forms.
