The word 看到 is formed by combining two individual characters, each contributing a core concept to create a new, unified idea. The first character, 看 (kàn), carries the fundamental meaning of "to look" or "to see", representing the active visual action. It is joined with the second character, 到 (dào), whose essential meaning is "to arrive" or "to reach", implying a successful attainment of a result. When fused, the literal action of "looking" conceptually merges with the result of "arriving at" that visual perception, thereby forming the compound meaning of "to catch sight of" or "to see and perceive", where the act and its successful outcome are encapsulated in a single term.
