Hangul Syllable Ssyeogs

It spells one Korean syllable; it is not a translation by itself. The Unicode decomposition of 쎣 is ᄊ + ᅧ + ᆪ: an initial consonant, the vowel ㅕ, and the final consonant cluster ㄳ (ㄱ + ㅅ). In compatibility-jamo notation, the same parts appear as ㅆ + ㅕ + ㄳ. A Korean word around it supplies its meaning.

Hangul was designed to write Korean speech by combining initial consonants, vowels, and final consonants into syllable blocks. The Sejong Annals, Korea's royal records, mention the script in 1443; its explanatory book, Hunminjeongeum, followed in 1446.

The writing system is called Hangul in South Korea; Choseongul is preferred in North Korea. Hangul blocks have passed through movable type, typewriters, and digital fonts, whose designs can give the component shapes different proportions.

Why does 쎣 sometimes split apart?

One Hangul syllable can be stored as a block or as jamo. The precomposed 쎣 and its equivalent conjoining-jamo sequence represent the same syllable. Fonts can draw the components with different spacing and proportions, but the spelling relationship stays the same.

Typing is separate from text normalization. With a Korean input method (IME), entering ㅆ, ㅕ, then final ㄱ + ㅅ may compose 쎣; the method resolves when those consonants belong together or start another syllable. Until composition is resolved, the input can appear as separate jamo.
