About
The traditional character 蠲 is structured with the component 虫 at the bottom, indicating an original association with insects, while the top element historically functioned as a phonetic indicator. Initially used to refer to a specific kind of insect, the character was appropriated in classical texts for a homophonous term meaning "to cleanse" or "to purify", leading to that meaning becoming primary. Over centuries, its semantic scope expanded to include "to exempt" in legal and fiscal contexts, reflecting a shift from concrete reference to abstract actions without alteration to its graphical form.
