This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
礜 combines 石 (stone) with 與, which likely contributes sound. The exact historical development is uncertain.
The top component 與 is complex and the bottom is 石 (stone). Picture a rare, mysterious stone with an elaborate name, but its meaning is unclear.
For ヨ, imagine a stone with a label that simply says 'Yo!' — a casual greeting that helps you remember the reading ヨ.
