The word 国度 is formed by combining two characters, each contributing a layer of meaning to create a holistic concept. 国 (guó) directly means "country" or "nation", referring to the physical, political entity. 度 (dù) originally signifies "measure" or "extent", but in this context, it extends metaphorically to imply a "realm", "domain", or "sphere of existence". Thus, the fusion creates a term that suggests not just a geopolitical state, but the broader, almost qualitative realm or kingdom defined by its unique character, order, and sovereignty, evoking a sense of a land with its own distinct measure and way of being.
