Hangul syllable 숷

It is a Hangul syllable block, not a word translated as “sweogs.”

“Sweogs” is an algorithmic label for its letter sequence, not a translation. Hangul blocks group letters into written syllables, so one block can be valid in a text string without being a familiar word by itself.

The writing system behind this block was created under Korean King Sejong; the first historical record of its creation dates to 1443. An explanatory book, Hunminjeongeum, followed in 1446. Before Hangul, Korean writing relied on Chinese characters and systems adapted from them; Hangul offered a regular way to write Korean sounds. The name Hangeul became widely used in the 1920s; in 1928, the holiday marking its creation was renamed Hangeul Day.

Why is 숷 built from jamo?

Hangul arranges letter pieces into one syllable block.

The underlying Unicode breakdown is ᄉ + ᅯ + ᆪ: ᄉ begins the block, ᅯ is a combined vowel, and ᆪ is a two-consonant ending. Change that ending and you get a different syllable.

How do I type 숷?

Use a Korean IME's syllable-composition sequence.

With the standard Korean two-set keyboard, enter ㅅ, ㅜ, ㅓ, ㄱ, ㅅ in that order. The IME combines ㅜ+ㅓ into ㅝ and ㄱ+ㅅ into final ㄳ, producing 숷.

Different fonts can give the stacked parts different spacing or proportions. That changes the silhouette, not the character.
