hospital
🏥 医 = doctor/medicine + 院 = courtyard/institution
医 means medicine or healing; 院 means a walled courtyard or public institution (also in 学院 academy, 法院 court). Together: the institution of medicine — a hospital.
院 — left ear 阝(阜) + complete 完
院 is a semantic-phonetic compound. The left 阝 (from 阜, mound/hill) suggests walls or enclosed terrain, hinting at an enclosed space. The right 完 (wán) provides the sound and originally meant 'complete', so 院 came to mean a walled courtyard or institution like a hospital or academy.
