Forms

īnfirmāria f (genitive īnfirmāriae); first declension[1]

Etymology

It is formed from Latin īnfirmus (“weak, sick”) + -āria.[1][2] The DMLBS treats it as the feminine of īnfirmārius “of the infirmary” used as a noun.[3]

Earliest recorded meaning

A Medieval Latin word,[4][2] it is first recorded in 1130, according to Köbler,[4] for the sick quarters of a monastery.[5]

Semantic evolution

It was above all the monastic word for the room or house where sick monks and nuns were cared for,[5][6] and it then came to mean a hospital in general.[1][7][8] Late medieval sources also use it for the nun in charge of the infirmary.[4][6][8] The spellings īnfirmēria and firmāria occur beside it.[4][5]

English infirmary (mid-15th century, first “sick bay in a monastery”) comes from Old French and directly from this Medieval Latin word.[2]
