Guys, I think I may have a proper definition for the name of Uinen. Here's the logic behind it: It must be made of two parts, the second of which is NEN:water. So the first element is probably UI. This occurs in Uilos, which means Ever-snow(or Ever-white). Besides that, there is also the Quenya form OIO, in Oiolossë, Oiomúrë, etc.
- The name is Quenya, so your suggestion is impossible. It's said to be adapted from Valarin in The War of the Jewels, and an earlier explanation in The Etymologies links the first element to "uilë" "long trailing plant, especially seaweed" . -Ederchil (Talk/Contribs/Edits) 16:48, 17 February 2013 (UTC)
