The word "出院" is formed through a direct and logical combination of two conceptual building blocks: the character 出, which means "to exit" or "to go out", and the character 院, which means "a courtyard" or "institution", specifically a hospital in this context. By placing them together, the composite meaning is visually and conceptually created, it depicts the single, unified action of "exiting the hospital", forming a new idea from the simple sum of its parts.
