Abstract
The word exchange had two meanings for Navarrus. A general one, which the Romans called permuta, referred to the exchange of one thing for another or of money for money. In a restricted sense, it applied to the exchange of money for money or to other contracts that did not fit into the Roman law classification: some types of acquisition, rentals, and so forth. Thus, exchange meant any contract of money for money that was not gratuitous, be it acquisition, deposit, or any other (CRM, par. 10).
