Hangul Syllable Myaj

By itself, it has no fixed translation; it contributes a syllable sound. 먖 is a Korean syllable written in Hangul; the surrounding Korean word supplies the meaning.

Why was Hangul created?

Hangul was designed to write Korean speech more directly. Its creation is dated to 1443. The explanatory book Hunminjeongeum was published in 1446; it explains the letters and how they join into syllable blocks. Before Hangul, Korean writing used Chinese characters, sometimes in systems adapted to represent Korean speech. This is the historical connection to Hanja, the Chinese-character tradition in Korean writing; Hangul developed as a separate script for representing Korean sounds.

Why can 먖 appear in different forms?

Both forms can represent the same Hangul syllable. Unicode can store 먖 as one precomposed block or as the canonically equivalent sequence 먖, made from joined jamo (Hangul letter components). Text normalization can combine that sequence into 먖. By contrast, ㅁㅑㅈ uses three compatibility jamo, the standalone forms of Hangul components, so it is a different character sequence even if a font makes it look like the block has been taken apart.
