About
As a phono-semantic compound, 翕 combines 合 (to close, to join) on top with 羽 (feathers, wings) below. Its original meaning describes a bird drawing in or folding its wings, a literal image of feathers brought together. This core sense of "closing up" extended to mean gathering, converging, or harmonizing, as used in classical texts to depict unified movement or the blending of elements. The character also developed an adverbial use, signifying agreement or synchronization, echoing the coordinated action of a bird retracting its plumage.
