This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
隝 combines ⻖ (hill, mound) with 鳥 (bird). The exact historical development is uncertain, but it likely originally referred to a bird-inhabited hill or island.
The left side ⻖ suggests a hill or mound, and the right side 鳥 is a bird. Picture a bird perched on a hill, but the overall meaning is unclear.
For トウ, imagine a bird on a hill making a toe-tapping sound: toe -> トウ, though the meaning is uncertain.
