[Middle English outlaue, from Old English ūtlaga, from Old Norse ūtlagi, from ūtlagr, outlawed, banished : ūt, out; see ud- in the Appendix of Indo-European roots + lög, law; see legh- in the Appendix of Indo-European roots.]
Word History: The word outlaw brings to mind the cattle rustlers and gunslingers of the Wild West, but it comes to us from a much earlier time, when guns were not yet invented but cattle stealing was. Outlaw can be traced back to the Old Norse word ūtlagr, "outlawed, banished," made up of ūt, "out," and lög, "law." An ūtlagi (derived from ūtlagr) was someone outside the protection of the law. The Scandinavians, who invaded and settled in England during the 8th through the 11th century, gave us the Old English word ūtlaga, which designated someone who because of criminal acts had to give up his property to the crown and could be killed without recrimination. The legal status of the outlaw became less severe over the course of the Middle Ages. However, the looser use of the word to designate criminals in general, which arose in Middle English, lives on in tales of the Wild West.
