What 밞 means
It is one Hangul syllable block assembled from Korean letters. Hangul syllables are written as blocks made from basic Korean letters. In 밞, ㅂ is the initial consonant, ㅏ the vowel, and ㄻ the final consonant cluster. ㄻ combines ㄹ and ㅁ; Korean calls the final-consonant position batchim. The label “balm” spells the parts in Latin letters; it is not a Korean definition.
Hangul was designed to give Korean speakers an accessible way to write Korean instead of relying on Chinese characters. The first record of Hangul is dated 1443; its explanatory book, Hunminjeongeum, followed in 1446. The name “Hangeul” appears in records from the early 1910s.
