What 뼂 means
It has no fixed meaning on its own. Hangul combines three jamo (letters)—an initial consonant, a vowel, and a final consonant—into one syllable. Korean word context supplies the meaning.
Hangul was created to make writing Korean more accessible than Classical Chinese. Its creation is documented in 1443; the 1446 guide 훈민정음 explains the script. Hangul later became part of modern Korean writing.
