The word 国王 is formed by combining two characters, each contributing a clear conceptual piece: 国 (guó), meaning "country" or "kingdom", and 王 (wáng), meaning "ruler" or "king". Placed together, they create a direct and logical compound where the first character specifies the domain and the second specifies the sovereign, visually and semantically fusing to mean "the king of a country". It is a straightforward conceptual union, picturing the ruler as intrinsically tied to the nation itself.
