This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
漻 combines 氵 (water) with 翏, which likely contributes the sound. The exact historical development is uncertain.
With water 氵 on the left and the rare component 翏 on the right, this kanji's meaning is unclear. Imagine a forgotten word for a type of water or liquid, now lost to time.
For リョウ, imagine a small, clear stream named Ryou: Ryou -> リョウ, flowing beside the water radical 氵.
