"As every schoolchild in Minas Tirith knows, in forming Sindarin compound-words the juxtaposition of N and R become DHR; thus "caran", "red", when conjoined with "rass", "horn", becomes "Caradhras", "Red-horn", one of the famed mountains of Moria. Similarly, "dun", "west", when conjoined with "randir", "wanderer", properly yields "dudhrandir", "west-wanderer". The form "Dunrandir" in the contemporary name of this pass erroneously retains the initial element in its original form, perhaps on analogy with the common compound "Dúnedain". We feel that this ought to be corrected, but we deemed it prudent not to broach the subject with the warden at Amrûnaur." -Findegil
