Mensa, Mensal Revenue

The Latin word mensa has for its primitive signification "a table for meals"; it designates by extension the expenses, or better, the necessary resources of sustenance, and generally, all the resources for personal support. He who lives at the expense of another, and at his table, is his "commensal". In ecclesiastical language, the mensa is that portion of the property of a church which is appropriated to defraying the expenses either of the prelate or of the community which serves the church, and is administered at the will of the one or the other.
