About
The character "衄" is structured with the radical "血" denoting blood and the component "丑" which primarily functions as a phonetic element. Its original and core meaning refers to nasal hemorrhage, or nosebleed. From this concrete physiological sense, the character's application broadened to describe military defeats, often in the compound "败衄", conveying the idea of a costly loss akin to bleeding. Further semantic extension led to the term carrying connotations of shame or disgrace, reflecting the humiliation associated with such setbacks.
