About
The character "窸" is a phonetic-semantic compound constructed from the radical "穴", denoting a cavity or hole, and the phonetic component "悉", which indicates its pronunciation. This formation corresponds to the character's function within the onomatopoeic term "窸窣", where it signifies a rustling sound frequently associated with noises emanating from confined spaces. While "窸" possesses no independent meaning outside such compounds, its structural composition has not altered, and its semantic application continues to be restricted to the imitation of specific subtle sounds.
