Which of the following is a synonym for the word hospital?

rubicund

per-exemption

sanatorium

infirmity

Sanatorium

Explanation:

Sanatorium is a synonym for hospital.

Rubicund means a reddish tint (think of Ron Weasley's reddish face) Per-exemption isn't a word ... but exemption means being counted out of something. (like if you don't have to pay taxes, you're exempt) Infirmity means sickness, not somewhere where the sick are treated.
