院 combines the radical 阝 (こざとへん), meaning "mound" or "place," with the phonetic 𠂤 (a variant of 完 or 宛). It originally referred to large buildings or compounds surrounded by walls — such as temples, government halls, or academies. Over time, it came to represent any large institution such as a hospital, school, or public facility.
