The word "客人" is formed through the combination of two characters: "客", which is itself an ideographic compound composed of "宀" (representing a roof or house) and "各" (historically indicating arrival or coming), thus depicting someone arriving at a dwelling as a guest; and "人", a pictogram symbolizing a person. Together, they create a semantic compound where "客" conveys the idea of visiting and "人" specifies the human aspect, resulting in the meaning of "guest" or "visitor" through this visual and conceptual integration.
