c.1300, ferren, foreyne "out of doors," from O.Fr. forain, from L.L. foranus "on the outside, exterior," from L. foris "outside," lit. "out of doors," related to fores "door;" spelling altered 17c. perhaps by influence of reign, sovereign. Replaced native fremd. Sense of "not in one's own land" is first attested late 14c.
