About
The character "剀", whose traditional form is "剴", is structured with the radical "刂" (刀) indicating a connection to cutting, combined with the phonetic component "豈" (simplified to "岂"). Originally denoting the physical action of sharpening or cutting, its meaning shifted over time to convey suitability or precision, as seen in the compound "剀切" meaning earnest or pertinent. This evolution from a literal sense of cutting to a figurative sense of appropriateness reflects a semantic extension where the concept of sharpness was applied to the accuracy of words or actions.
