Hangul Syllable Jak

It has no established standalone word meaning.

잨 is read roughly as “jak”: ㅈ begins with a sound like English j in “jam,” ㅏ is the a vowel, and final ㅋ closes with a clipped k. Hangul fonts can draw these parts differently without changing the character.

Hangul was created in 1443 so Koreans could write their language without relying on Chinese characters. The Hunminjeongeum, its guide, appeared in 1446; Hangul became Korea's official national writing system in 1894. Whether the Mongolian Phags-pa script influenced Hangul's design remains debated; it is not an established ancestor.
