Hangul syllable huss

Use ㅎ, then ㅜ, then ㅆ in a Korean IME.

The Hangul jamo—the letters that build syllable blocks—are ᄒ + ᅮ + ᆻ. A Korean input method accepts the corresponding keyboard forms, ㅎ + ㅜ + ㅆ, and normally composes them as 훘; ㅆ is the final consonant in the block.

Unicode normalization can represent this same syllable as one precomposed character or as three conjoining jamo. These are different text sequences; if a field requires one code point, it must retain the precomposed 훘.

What does 훘 mean by itself?

By itself, 훘 gives you a syllable, not the whole meaning.

The block combines an initial consonant, a vowel, and a final consonant. If it arrives alone, use the Korean word or sentence around it to understand what it contributes. The 1446 Hunminjeongeum, the document introducing Hangul, explains this start-middle-end structure.

Hangul was designed to record spoken Korean more directly than the Chinese-character systems then used, including Idu, a way to write Korean with Chinese characters; its creators aimed to make written Korean accessible beyond the literate elite. Later it was used alongside Hanja (Chinese characters) in Joseon-era Korea and became the script of modern Korean. Scholarship compares its design with Chinese traditions for classifying speech sounds and the earlier Phags-pa writing system, while also describing Hangul as an independent Korean design.
