Hangul syllable Jabs

잢 is a Korean syllable block, not a complete message by itself. Its parts are Hangul letters called jamo: ㅈ is the initial consonant, ㅏ the vowel, and ㅄ the final double batchim (겹받침). Read it as a syllable; in a Korean word, that word supplies the meaning.

Hangul was devised under King Sejong in 1443; its explanatory guide, Hunminjeongeum, appeared in 1446. The new alphabet gave Korean speakers a more direct way to write their language than Chinese characters allowed. 잢 is one possible combination in that system, not a separate historical sign. Hangul began as a script for Korean in Joseon Korea and remains the script used for Korean today.

Why does the pronunciation change?

The final ㅄ follows Korean sound rules. Alone or before another consonant, it closes like an unreleased p: say roughly “jah,” then close your lips without releasing the p. Before a Korean ending that starts with a vowel, ㅂ stays at the end while ㅅ moves to the next syllable as a tense s.

How do I enter this block?

With Korean two-set input, enter ㅈ, ㅏ, ㅂ, then ㅅ. On a standard QWERTY layout, press w k q t. A Korean IME (input software) assembles the syllable as you type; temporary forms are normal because it builds Hangul blocks step by step.

Unicode can store this syllable as one precomposed block (NFC) or as separate jamo letters (NFD). The two forms are canonically equivalent, but text tools may show the separate letters even when they make the same syllable.
