This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
醶 combines 酉 (sake jar/alcohol) with 僉, which likely contributes a phonetic element. The exact historical development is uncertain.
The left side is a sake jar 酉, and the right side 僉 looks like a complex assembly. Picture a mysterious, ancient brew in the jar—its meaning is as unclear as the liquid inside.
For ゲン, imagine a genie emerging from the sake jar: genie -> ゲン, and the genie's magic makes the kanji's meaning elusive.
