Hangul Syllable Heup

It is one Korean syllable, so context supplies the message.

Hangul writes Korean with individual consonant and vowel letters, called jamo, arranged in square syllable blocks. In 흪, ㅎ + ㅡ + ㅍ form one block; by itself, it may be a fragment, so the surrounding Korean text tells you the intended word or message.

Hangul’s documented milestones are 1443 and 1446: King Sejong’s court devised the script in 1443 and introduced it with a published explanation in 1446. The system was designed to represent Korean speech systematically instead of relying only on Chinese characters.

How do I type 흪?

Use a Korean IME and enter ㅎ, ㅡ, then ㅍ.

On the Korean two-set keyboard layout, G types ㅎ, M types ㅡ, and V types ㅍ; the input method combines them into 흪. Other Korean layouts put those letters on different keys.

If your editor accepts decomposed Hangul jamo, enter 흪.

Why does 흪 look different?

Fonts can change the strokes without changing the syllable.

Unicode defines this as one precomposed Hangul syllable and also gives its canonical decomposition into an initial consonant, vowel, and final consonant. Fonts arrange those parts in a square cell, so stroke weight, spacing, or the bottom letter can look different.

Compare the final consonant: 흪 ends in ㅍ, while 흡 ends in ㅂ. The different bottom letter changes the character; a font’s drawing alone does not.
