Hangul syllable Jyigs

It is a Hangul syllable block; its Unicode name labels its parts.

Hangul builds syllable blocks from jamo (individual letters): ᄌ is the initial consonant, ᅴ the vowel, and ᆪ the final cluster here. Unicode’s label “Jyigs” joins short names for those components; it describes the block rather than translating a Korean word.

Hangul was created under King Sejong to write Korean with letters organized around speech sounds; its creation is recorded in 1443. The 1446 book Hunminjeongeum explained the letters and how they form syllable blocks. Before Hangul, Korean writing also used Hanja, a system of Chinese characters. Earlier names for the script included Jeongeum and Eonmun; from 1894 it was commonly called Gukmun or Gukseo. “Hangeul” appears in records from the early 1910s, though its first use is disputed; it became widely used after the public holiday was renamed Hangeulnal in 1928.

How do I type 즧?

Use Korean input with the 2-set keyboard layout.

Type wmlrt: w enters ㅈ, m+l form ㅢ, and r+t form the final ᆪ. The input method assembles those keystrokes into the precomposed block.

Hangul fonts may shape and space the component strokes differently within the square syllable cell. That variation in layout does not make it a different character.
