What 쀄 means
It is one Korean syllable block, not a stand-alone idea.
Hangul arranges Korean consonants and vowels into a block for each syllable. In 쀄, ㅃ is the starting consonant and ㅞ the vowel; a Korean word or name containing it supplies the meaning.
Hangul's earliest surviving creation record dates to late 1443. The explanatory manuscript Hunminjeongeum followed in 1446; those dates belong to the writing system, not a separate origin for 쀄.
Questions people ask
1Why does 쀄 look different in different fonts?
Different Hangul fonts can shape or position a block's parts differently. The visual change does not change the character.
