But in some other words, conversely, Spanish o corresponds to Portuguese oi, e.g., Spanish cosa, Portuguese coisa "thing"; Spanish oro "gold", Portuguese usually ouro, but sometimes oiro.
Im Gegenzug entspricht jedoch spanisches o in manchen Wörtern portugiesischem oi, vgl. span. cosa, port. coisa ‚Sache‘; span. oro ‚Gold‘, port. gewöhnlich ouro, aber selten oiro.
