Hangul syllable Gweos

It is a Hangul syllable block; “gweos” labels its structure.

Hangul is the Korean alphabet, and its consonant and vowel letters are called jamo. 궛 combines an initial ᄀ, a vowel ᅯ and a final ᆺ into one block. The Unicode name “gweos” is assembled from those parts; it describes the structure, not a Korean word's meaning.

The script's earliest official record dates its creation to December 1443. The 1446 Hunminjeongeum, an explanation of the new writing system, set out its purpose: making Korean easier to write for people who had relied on Chinese characters. Earlier, Idu, Gugyeol and Hyangchal adapted Chinese characters to write Korean. Hangul later spread through religious, practical and literary texts, became the official national writing system in 1894, and its modern spelling was based on a 1933 unified-spelling draft.

A Korean keyboard builds the block

A Korean input method assembles the block from jamo.

On a Korean keyboard, enter ㄱ, form ㅝ, then add ㅅ; the input method composes them into one block. These compatibility jamo are distinct from the conjoining jamo ᄀ, ᅯ and ᆺ used for a decomposed syllable. Unicode normalization can convert between that sequence and the precomposed 궛.
