Húrin
{Throughout The War of the Jewels, Christopher Tolkien mentions that, while working on the later parts of the Narn - specifically The Wanderings of Húrin - and the genealogies of the 1950s, Tolkien altered "Eleðwen" to "Eðelwen." I'm unsure if the etymological considerations of Quendi and Eldar - in which, for example, [n] + [r] >> [ðr] - or something else prompted his adoption of the earlier form in the published work. Maybe just oversight. In Q&E, Tolkien mentions that eðel was the "general word" for "elf," and elen (pl. elin, eleðrim) "was only used in histories or the works of the Loremasters." Although, of course, that last consideration doesn't necessarily preclude the possibility of "Eleðwen" as a form... 😛}
