Hangul syllable 퉛

Its documented standalone word use is a Biyangdo name for 톳. 퉛 is a Hangul syllable block made from initial consonant ㅌ, vowel ㅝ, and final consonant ㅅ.

A 2010 National Institute of Korean Language survey records 퉛 as a Biyangdo name for 톳, a brown seaweed. This supports a local word use, not a general Korean synonym.

Why does 퉛 exist as a block?

It follows Hangul’s system for spelling Korean syllables. Hangul was created in 1443; the 1446 Hunminjeongeum publication, a guide to the writing system, explained its purpose and principles. It gave Korean a purpose-built way to represent its sounds with letters rather than relying on Chinese characters alone.

Idu, Gugyeol, and Hyangchal were other methods of writing Korean that adapted Chinese characters to Korean words or grammar. They belong to the wider history of Korean writing; 퉛 itself is assembled from Hangul letters.

Someone sent me 퉛—what should I do?

Ask what they mean unless you know the local usage. The Biyangdo reading is regional; outside that vocabulary, a bare syllable may look like a typo or leave the message unclear. For the seaweed in general Korean, 톳 is the standard term.

Text software can represent 퉛 as the decomposed jamo sequence 퉛. That can affect selection, searching, or matching until the text is normalized, without changing the syllable.
