Hangul Syllable Hih

As of 2026, it has no established standalone word meaning. Unicode derives “Hih” from its components: initial consonant ᄒ, vowel ᅵ, and final consonant ᇂ. These are Hangul jamo—Korean consonant and vowel letters that combine into syllable blocks—so the name describes the sequence, not a Korean word.

Hangul was designed to write Korean with its own consonant and vowel letters. Before the script, Korean writing relied heavily on Chinese characters; Hangul grouped its letters into syllable blocks so they could represent Korean syllables directly. The script was created in 1443, and its explanatory text, Hunminjeongeum (“Correct Sounds to Instruct the People”), was published in 1446.

This block belongs to Hangul’s modern precomposed set. Older and archaic Korean syllables can instead be written as sequences of conjoining jamo—separate Korean consonant and vowel letters arranged to form a syllable.

Why does a Korean regex end with 힣?

It marks the end of the modern precomposed Hangul range. In a regular expression (regex), the hyphen in [가-힣] means “through,” so the range matches modern syllable blocks from 가 to 힣. It does not include archaic Hangul sequences or every other Korean writing character.

Fonts may vary the components’ size and placement inside the square block without changing the character.
