Hangul syllable Muk

It marks a syllable’s sound, not a word definition. Hangul groups its letters into blocks; ㅁ begins this one, ㅜ is its vowel, and ㅋ is its batchim, the consonant at the end. The Latin-letter spelling “muk” labels the reading; the surrounding Korean word supplies the meaning.

Why was Hangul created?

To write Korean speech more directly and easily. The first record of Hangul’s design is dated 1443. In 1446, the Hunminjeongeum, a text explaining the alphabet, set out its design. Korean writing had relied on Chinese characters (hanja), including Idu, a system that adapted those characters to write Korean; that approach was cumbersome and represented speech indirectly.
