Etymology

From Middle English foreyn, forein, from Old French forain, from Vulgar Latin *forānus (“outsider, outlander”), from Latin forās (“outside, outdoors”) or forīs (“outside, outdoors”). Displaced native Old English elþēodiġ (“foreign”) and now-dialectal English fremd, from Old English fremde (“strange, foreign”). The silent -g- added perhaps by analogy with reign (compare also sovereign which was similarly altered).
