Hangul syllable Ssweolh

It is a written Korean syllable; its meaning depends on context. Unicode breaks it into ᄊ + ᅯ + ᆶ: an initial consonant, a vowel, and a final consonant cluster. Keyboard forms of those parts are ㅆ + ㅝ + ㅀ.

Hangul was created in 1443 to write Korean. A book titled Hunminjeongeum, published in 1446, explained its design and how letters form syllables. The square-shaped Phags-pa script was commissioned in 1265 for use across the Mongol empire and promulgated in 1269; its influence on Hangul remains debated.
