Hangul Choseong Ssangpieup

It is the tense p initial, waiting for a vowel. ᄈ is the conjoining initial—the leading consonant form corresponding to ㅃ. Pair it with the conjoining vowel ᅡ: the sequence 빠 composes as the syllable 빠. In ssangpieup, ssang means “double” and pieup names the Korean p-series consonant; the doubled shape marks one tense consonant, often romanized pp, not two p sounds.

Hangul was devised in 1443 to write Korean speech directly, rather than relying on Classical Chinese characters for writing; an explanatory book introducing the script appeared in 1446. In texts from the 15th century, doubled initials such as ㅃ mainly appeared in constructed Korean readings of Chinese characters. By contrast, ㅅ-initial clusters such as ㅽ could spell Korean consonant clusters or tense sounds. By the 20th century, ㅃ represented the tense consonant in modern spelling. A 2023 analysis argues that the tense p series may connect to older clusters, citing spellings from the early 16th century.

Why does ᄈ look different from ㅃ?

They are two Unicode forms of the same Korean initial. ᄈ is a conjoining jamo, designed to join a following vowel in a syllable block. ㅃ is its compatibility-jamo counterpart, a standalone-shaped form used in charts and older text interchange. Unicode treats the pair as compatibility-equivalent, but encodes them as different characters.

An isolated ᄈ can therefore sit or shape differently from ㅃ. As of 2026, modern browsers generally support the relevant Hangul shaping; support in other apps is less even.
