Hangul syllable Ggyogg

By itself, 꾞 has no fixed word meaning. It is a Hangul syllable block; its meaning comes from the Korean word that contains it. On a Korean keyboard using the common 2-set layout, Shift+R, Y, Shift+R builds it; Korean input software joins the opening consonant, vowel, and closing consonant as you type.

King Sejong's project produced Hangul in 1443 to write Korean more directly because Chinese characters did not fit spoken Korean well and were hard for most people to learn. The new system was explained in 1446 in Hunminjeongeum, a guide to the new letters and their sounds. Before Hangul, Idu, Gugyeol, and Hyangchal adapted Chinese characters for Korean writing. Hangul later appeared in Buddhist and Confucian texts, practical writing, and private letters. It became official national writing in 1894, then lost that status under Japanese rule in 1910.

Why does 꾞 look like a square?

Hangul puts its letters together inside square syllable blocks. 꾞 combines initial ㄲ, vowel ㅛ, and final ㄲ. The last ㄲ closes the syllable; it is part of the block, not an add-on. These individual Hangul letters are often called jamo.

The same sequence can be stored as one precomposed syllable or as individual Hangul letters. Korean input software assembles modern letters into blocks, and fonts shape the glyph. Stroke design or spacing can vary while the character identity stays the same.
