Hangul syllable Ssyeo

With a Korean keyboard, type ㅆ then ㅕ.

On the standard two-set Dubeolsik Korean keyboard, Shift+T enters ㅆ and U enters ㅕ. As of 2026, the Korean input method editor (IME), the software that turns keystrokes into Hangul, joins them as 쎠; with English input active, those keys produce Latin letters instead.

The conjoining Jamo sequence 쎠 is the decomposed form of 쎠 and may display as separate letters if an app or font handles it differently. The similar-looking ㅆㅕ uses compatibility Jamo and is a different Unicode sequence.

Where did 쎠 come from?

It follows Hangul's system for writing Korean in syllable blocks.

Hangul builds each syllable from consonant and vowel letters called Jamo. The Sejong Annals, a court chronicle, mention Hunminjeongeum in 1443; a book published in 1446 explains the letters, sounds, and syllable rules. That history is for Hangul's writing system, not a separate invention of this one block.

Before Hangul, Korean was written using Chinese characters and Korean writing methods adapted from them, including Idu, Gugyeol, and Hyangchal. These systems took considerable learning; Hangul represented Korean more directly. It spread in Buddhist and Confucian books, practical publications, and personal letters, and became the official national writing system in 1894.

Does 쎠 mean anything by itself?

By itself, 쎠 has no fixed word or message meaning.

It contributes one syllable to a Korean word, so an isolated block is a fragment. Read the full Korean word or sentence to know what it says.
