The word 归来 is formed by combining two individual characters, each contributing its core meaning to create a new, unified concept. The first character, 归 (guī), carries the essential idea of "to return" or "to go back". It is joined with the second character, 来 (lái), which means "to come". Their combination is not merely additive but synergistic, blending the directional notions of returning and arriving to vividly express the complete action of "coming back" or "returning home", evoking a sense of arrival at the point of origin.
