Hangul Syllable Twess

퉸 is one Hangul syllable assembled from three Korean letters. Its parts, ㅌ, ㅞ and ㅆ, form an opening consonant, a vowel and a final consonant. Read it within a Korean word; the surrounding word supplies its sound and meaning. “Twess” is a construction label for the letter sequence, not a translation.

Hangul was completed under King Sejong in 1443, and a guide to the system appeared in 1446. It was designed to make writing accessible to ordinary people, since the Chinese-character writing then used did not fit Korean sounds well; arranging letters into syllable blocks was part of its design from the start.

The system was introduced as Hunminjeongeum, “Proper Sounds for Instructing the People”; later names included eonmun (“vernacular writing”) and, by 1894, gukmun (“national writing”). Scholars debate whether the Phags-pa script influenced Hangul’s vowel design or whether the design came from Hangul’s own analysis of speech sounds. That debate concerns the writing system, not a direct ancestor of 퉸.

How do I type 퉸?

Type ㅌ, ㅞ, then ㅆ with a Korean input method.

A Korean input method (IME) combines the opening consonant, vowel and final consonant as you type; it may show an unfinished syllable block until the final letter arrives.

Unicode normalization can split this precomposed syllable into its component Hangul letters and combine them again. Software can therefore store the same text in a precomposed or decomposed form; normalization treats those forms as equivalent.
