Hangul syllable Ssweog

It is one Korean syllable block; the surrounding word supplies its meaning.

Hangul arranges its alphabet letters, called jamo, into blocks, one syllable at a time. In 쒁, ㅆ begins the syllable, ㅝ is its vowel, and ㄱ ends it.

Hangul was created in 1443; the 1446 book Hunminjeongeum, an introduction to the script, explains how consonant and vowel letters form syllables. The alphabet was designed to write spoken Korean. Korean texts also used Hanja, Chinese characters, for centuries; Hangul later became the main script for Korean.

How do I type 쒁 on a Korean keyboard?

Enter ㅆ, then ㅝ, then ㄱ with Korean 2-set input.

A Korean IME (input method) combines them in order: initial consonant, vowel, then final consonant. If the letters stay separate, switch the input language to Korean and enter them in that order.

Why does 쒁 look different in different fonts?

Fonts can reshape the same letters inside the block.

Hangul typefaces adjust the proportions and spacing of the initial, vowel, and final letters to fit one square block, so 쒁 may look tighter or more open while remaining the same character.
