The language represented in this history by English was the Westron or 'Common Speech' of the West-lands of Middle-earth in the Third Age. In the course of that age it had become the native language of nearly all the speaking-peoples (save the Elves) who dwelt within the bounds of the old kingdoms of Arnor and Gondor ... At the time of the War of the Ring at the end of the age these were still its bounds as a native tongue. (Appendix F)
