Hangul syllable Cyeols

It writes one Korean syllable, not a reaction. 쳜 combines the opening consonant ㅊ, the vowel ㅕ, and final ㄽ, a two-consonant cluster made from ㄹ + ㅅ. In Korean text, the surrounding word or sentence gives the syllable its role.

Hangul, the Korean writing system, was created under King Sejong in 1443 to write Korean speech. Its original name was Hunminjeongeum; that is also the title of the explanatory book published in 1446, which records how the letters and syllables work. Those dates belong to Hangul as a whole, not to a separate invention of this syllable.

How do I type 쳜?

Use Korean input and press C, U, F, T on Dubeolsik. Dubeolsik is the standard two-set Korean keyboard layout. Those keys enter ㅊ, ㅕ, ㄹ, and ㅅ; a composing input method joins the last two into final ㄽ and reshapes the block as you type. If the letters remain separate, enable syllable composition in your Korean input settings.

Why is 쳜 one square?

Hangul arranges one syllable’s parts inside a square cell. Unicode encodes the completed cell as a precomposed syllable and also supports its component jamo. A Korean input method may show separate jamo while you type; the font draws the finished block. If a box or fallback character appears, the font lacks this glyph.
