Hangul syllable Ggyaek

꺸 writes one Korean syllable in a single block. It joins ᄁ, ᅤ, and ᆿ: an opening consonant, a vowel, and a closing consonant. These pieces are called jamo, the letters used to build Hangul syllables. Unicode can store the same syllable as one precomposed character (a ready-made block) or as conjoining jamo, which join into a syllable. Compatibility jamo are separate stand-alone forms and do not combine by the same rule.

Hangul was created in 1443; in 1446, its purpose and design were explained as an accessible way to write Korean alongside the Chinese-character methods then used in Korea. It later appeared in Buddhist and Confucian texts and in practical, everyday writing, and gained official national status in 1894.
