sanatorium
n. countablen. a special hospital or building where people go to rest and get better from a long illness. It was very common in the past for people with tuberculosis to stay there for a long time.
n. a facility or building designed for the treatment of chronic diseases, particularly tuberculosis, through rest, fresh air, and a healthy environment. Often implies a long-term residential stay rather than acute medical intervention.
The old sanatorium now serves as a luxury hotel.
During the early twentieth century, many families moved to the mountains to stay at a sanatorium for the winter.
The architectural design of the sanatorium emphasized wide windows and open-air terraces to ensure patients received maximum exposure to sunlight and fresh mountain air.
Haplology from Latin sanatus (past participle of sānō (“to cure, to heal”)) + Latin -torium. Alternatively, alteration of sanitarium influenced by words like curatorium and moratorium.
