The word 来到 is formed by combining two characters that each convey a distinct phase of movement toward a point. The first character, 来 (lái), conceptually represents the action of "coming", or moving toward a reference point (often the speaker). The second, 到 (dào), signifies "arriving at" or reaching a specific destination or goal. Together, they sequentially depict a complete trajectory: the motion toward followed by the attainment of an endpoint, merging into a single concept of "to come and arrive" or "to reach". This formation visually and notionally strings the beginning and end of a journey into one cohesive idea.
