Westron

thumb|upright=1.75|According to Tom Shippey, Tolkien invented parts of [[Middle-earth to resolve the linguistic puzzle he had accidentally created by using three different pseudo-translated European languages for those of peoples in his legendarium.]]

Westron (called Adûni in Westron, or Sôval Phârë, meaning "Common Speech") is the constructed language that was supposedly the Common Speech used in J. R. R. Tolkien's world of Middle-earth in the Third Age, at the time of The Lord of the Rings. It ostensibly developed from Adûnaic, the ancient language of Númenor. In practice in the novel, Westron is nearly always represented by modern English, in a process of pseudo-translation which also sees Rohirric represented by Old English. That process allowed Tolkien not to develop Westron or Rohirric in any detail. In the Appendices of the novel, Tolkien gives some examples of Westron words.
