Hangul syllable jyaeb

As a character, 쟵 writes a syllable, not a fixed meaning. The Korean input sequence is ㅈ, ㅒ, ㅂ: an initial consonant, a vowel, and a final consonant. Unicode's decomposed jamo sequence is 쟵. The block represents the syllable's spelling and sound; its surrounding Korean word or name supplies the meaning.

The KS C 5601-1992 Johab standard included this kind of precomposed block so computers could encode modern Korean syllables. That is the history of a digital character inventory; it does not date Hangul or the spoken syllable.

Older Korean forms are a separate layer: some use sequences of joined jamo that cannot be written with this modern precomposed block inventory.
