What 乽 means
It is Korean-made hanja for 잘 in a royal title.
乽 appears in 乽山君, the princely title of the future King Seongjong, later a king of Korea’s Joseon dynasty. Here it writes the Korean syllable 잘, pronounced roughly “jahl,” with a final l; it is not a free-standing substitute for 잘, the everyday Korean word meaning “well.”
A Joseon court record from 1461 writes the title 者山君; a 1467 record has 者乙山君. Those dates belong to the recorded title spellings, not to the origin of the single character 乽.
Is 乽 the same as 者乙?
In this title, 乽 is the compact counterpart of 者乙.
者乙山君 is the expanded spelling recorded in 1467; 乽山君 uses one Korean-made character in the same position. They are related title spellings, but not interchangeable glyphs.
This is Korean Gukja (國字), a Han-character form made in Korea to write Korean. It belongs to a longer history of adapting Chinese characters to represent Korean sounds or help mark readings; Idu, Hyangchal, and Gugyeol are other named practices in that history.
Why does 乽 look wrong?
A box or a different style is usually a font issue.
On the 2026-09-10 check, Taiwan’s official CNS character listing showed 乽 in several CJK fonts, while a character reference noted that its display can depend on the environment. If the glyph is missing or looks slightly different, use a font or character picker with CJK coverage; substituting 者乙 changes the text to the expanded spelling.
Historical Korean hanja: in modern prose, 乽 reads as a deliberate reference to an old royal title.
Do not use 乽 as a casual substitute for 잘; its documented role is a title syllable.

Questions people ask
1Why does 乽 show as a square?
The font lacks a glyph for this character. A Korean hanja or other CJK font with coverage can display 乽 without changing the text.
