This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
浯 combines 氵 (water) with 吾, which likely contributes the sound. The exact historical development is uncertain.
Water 氵 beside 吾 suggests a name or place, but the meaning is unclear. Think of it as a mysterious water-related character.
For ゴ, imagine a go board floating on water: go -> ゴ, and the water 氵 ripples around the 吾 shape.
