Hangul Syllable Hyeolt

Inside a word, 혍 is one syllable; the word gives its meaning. The jamo in 혍—the letters combined into Hangul syllable blocks—are ㅎ (initial consonant), ㅕ (vowel), and ㄾ (final consonant cluster). Unicode's position-specific conjoining sequence is ᄒ + ᅧ + ᆴ. The first set uses compatibility forms; the second marks each letter's initial, vowel, or final position.

Hangul, the Korean writing system, was designed so letters could combine into syllable blocks. The earliest documentary evidence is from 1443; the 1446 Hunminjeongeum, an explanatory text introducing the script, says the letters were made easy to learn so people could write Korean in daily life. It explains arranging letters as initial, medial, and final parts. 혍 is one block built by those rules.

The older Korean letter ㆆ is historically connected to ㅎ as a strengthened throat consonant. That history belongs to 혍's initial letter, not to the whole syllable as an independent sign.
