This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
潽 combines 氵 (water) with 普, which likely contributes the sound. The exact historical development and original meaning are uncertain.
With water 氵 and 普 (widely), imagine water spreading widely, but since the meaning is unclear, treat this as a visual placeholder.
For ホ, picture a wide 普 hose 氵 spraying water: hose -> ホ.
