Fowl is from Old English fugol and linked with Teutonic words for fly. (Johnson notes, "It is colloquially used of edible birds, but in books of all the feathered tribes.") Foul is from Old English fl. "Foul play" first appears in The Tempest (1610), a natural successor to the "fair play" used twice in King John.
