About
The character "嘁" is structured with the mouth radical (口) on the left to signify its connection to sound and the component "戚" on the right primarily providing phonetic guidance, resulting in an onomatopoeic formation designed to mimic whispering or rustling noises. It is most frequently seen in reduplicated expressions such as "嘁嘁喳喳" to convey the notion of subdued chatter or murmuring, and its semantic application has consistently focused on representing these types of auditory phenomena from its earliest documented use.
