The word 裁决 is formed by combining two characters, each contributing a core meaning to create a new, unified concept. The first character, 裁, carries the fundamental sense of "to cut" or "to trim", which evolved metaphorically to mean "to judge" or "to decide", akin to cutting through an issue to separate right from wrong. The second character, 决, means "to decide" or "to determine", emphasizing finality and resolution. When merged, the word 裁决 visually and conceptually portrays the act of making a definitive, authoritative judgment, as if cleanly severing a matter to reach a conclusive decision.
