𢍏聲ào — gives the soundthe worn body under the roof, no longer read on its own
Under the roof (宀) is the southwest corner, the deepest part of the old house — the recess where light barely reaches. 𢍏 carries the sound ào. From the dark inner corner the word turns abstract: deep, hidden, hard to reach: 深奧、奧秘、奧妙.
