The word "上来" is formed through the conceptual and directional combination of its two component characters: "上" (shàng), which carries the core meaning of upward movement or a higher position, and "来" (lái), which indicates movement toward the speaker or a point of reference. Their fusion creates a single unit that conceptually maps a path of motion originating from a lower or distant point and terminating in an upward or proximate arrival. This formation is inherently spatial and metaphorical, blending the vector of "上" with the trajectory of "来" to depict a complete, oriented action rather than simply listing two separate ideas.
