The Chinese word "上诉" is formed through the conceptual combination of its two component characters: "上", meaning "upward" or "above", and "诉", meaning "to tell", "to relate", or "to appeal". Together, they create a new, unified concept where the directional "上" metaphorically indicates a move to a higher level or authority within a hierarchical system (like a court), and "诉" specifies the nature of the action as a formal telling or pleading. Thus, the compound literally and conceptually means "to appeal upward", perfectly capturing the idea of taking a case to a higher court for a re-evaluation of a decision.
