xenodochium
A room (or separate guesthouse) in a monastery for the temporary accommodation of guests or pilgrims.
Gregory the Great orders that the accounts of xenodochia should be audited by the bishop (Epist. iv. 27).
Where it comes from
From Latin, from Ancient Greek ξενοδοχεῖον (xenodokheîon, “place for strangers, inn”) from ξένος (xénos, “guest, stranger, foreigner”) + δέχομαι (dékhomai, “receive, accept”).
