The word "来讲" is formed through a metaphorical and functional fusion of its two constituent characters: "来", which carries a sense of "to come" or directional movement toward a point, and "讲", which means "to speak" or "to explain". Their combination conceptually blends the act of verbal explanation ("讲") with the directional notion of approaching a topic or perspective ("来"), thereby creating a single unit that implicitly frames the following statement as arriving from or being delivered from a specific standpoint or line of reasoning.
