医院 (yī yuàn) literally means 'medical institution' — the character 医 (yī) means 'medicine' or 'medical treatment', and 院 (yuàn) means 'institution', 'compound', or 'courtyard', often used for formal organizations like schools or hospitals. Together, they refer to a place where doctors, nurses, and other healthcare professionals diagnose, treat, and care for patients.

Hospitals in China range from small community clinics to large provincial medical centers. The word is neutral and formal, used in everyday speech as well as official contexts. It’s commonly paired with verbs like 去 (qù, 'to go to'), 在 (zài, 'to be at'), or 看病 (kàn bìng, 'to see a doctor'). Unlike more colloquial terms like 诊所 (zhěn suǒ, 'clinic'), 医院 implies comprehensive services including emergency care, surgery, and inpatient wards.
