Hangul Syllable Jeop

Its word supplies the meaning; 젚 contributes one syllable.

젚 is a single consonant–vowel–consonant syllable: ㅈ starts it, ㅓ is its vowel, and ㅍ ends it. Without the surrounding word, you can identify the syllable but cannot reliably infer the intended meaning.

The story behind this block begins with Hangul: its creation is recorded in 1443, and Hunminjeongeum, a book explaining the new script, appeared in 1446. Before then, written Korean adapted Chinese characters through systems such as Idu, Gugyeol, and Hyangchal, which represented Korean words and grammar.

Hangul and Hanja (Chinese characters used in Korean writing) appeared together in mixed-script writing by 1447. After 1945, North and South Korea followed different paths: North Korea abolished Hanja in 1949, while Hangul-only writing became the South Korean norm during the 1990s.

Why does Unicode split 젚 into jamo?

A Hangul syllable can be stored as letters or as one block.

Hangul letters are called jamo. In Unicode's NFD form, this syllable is 젚; NFC recomposes those conjoining jamo into 젚.

A Hangul-aware renderer can still display the NFD sequence as a single block. Normalization can therefore change the stored characters while the visible syllable stays the same.
