Hangul syllable Byaep

It represents one Korean syllable; the word around it supplies the meaning.

Unicode's name for the sequence is “byaep.” The block joins three jamo (Hangul letters): ᄇ begins it, ᅤ is its vowel, and ᇁ ends it. Unicode text normalization can also switch between this single block and a sequence of separate jamo without changing the written syllable.

How did Hangul syllable blocks develop?

They belong to a writing system created for Korean.

Hangul was created in 1443 under King Sejong; a 1446 book, Hunminjeongeum, explained its letters and how they form syllables. Earlier Korean writing used Chinese characters, including Idu, a separate system that adapted them to Korean words and grammar but could not represent Korean fully. Hangul offered reusable letters for writing Korean speech.

Hangul later served government, religious, literary, home and practical writing, sometimes alongside Hanja (Chinese characters used in Korean texts). Older names included eonmun (“vernacular writing”). Reforms in the Joseon kingdom gave it the title Gukmun (“national script”) in 1894. Under Japanese colonial rule, official support was curtailed, but study and teaching continued. After liberation in 1945, Hangul education and public use were promoted again. The name Hangeul came into wide use by 1928.
