A place in a school, workplace, or institution where sick or injured people receive basic medical care.
From Latin 'infirmarius,' one who tends to the infirm, derived from 'infirmus' (weak or ill). The suffix '-ary' indicates a place for that purpose.
Every school has an infirmary but most people have never stopped to realize it's literally 'the infirm place'—a room named after people being weak. In the days before hospitals, the infirmary was where you had to go when your body betrayed you.
