Etymology
From Old French legion, from Latin legio, "a gathering" or "a levied army" — related to legere, "to gather" (the same root gives us legend and lecture). The everyday sense of "a huge number" comes from the Bible, where a man possessed by many spirits says "my name is Legion, for we are many."
