This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
The exact historical development of 覍 is uncertain. It visually combines 小 (small) and 見 (see), but whether this reflects the original meaning is unclear.
Imagine a small eye (小 over 見) trying to see something tiny, but the meaning remains elusive.
