About
The character "切" originates from a phono-semantic structure integrating the radical "刀", indicating a knife, with the component "七" serving a phonetic role, initially expressing the concrete action of cutting or severing with a blade. This fundamental meaning gradually extended into abstract realms, where the precision of cutting metaphorically informed concepts of close alignment or exact correspondence, as seen in terms describing ideas that fit precisely. Subsequent developments embraced connotations of urgency and earnestness, likening sharpness to emotional or situational intensity, while specialized applications emerged, such as in mathematics to denote tangency, all without departing from its original compositional elements or its enduring association with keen-edged instruments.
