Author's Response: I appreciate it. The following is quoted from http://www.omniglot.com/writing/tengwar.htm :
"J.R.R. Tolkien created many languages throughout his life. He wrote in one of his letters that the tales of Middle-earth (The Hobbit, The Lord of the Rings, The Silmarillion, etc) grew from these languages, rather than the languages being created for use in the stories.
Tolkien also created a number of different alphabets to write his languages - Tengwar, or Feanorian letters, is the one which appears most frequently in his work. The way the vowels are indicated in Tengwar resembles Tibetan and other Brahmi-derived scripts.
[Tengwar can be] Used to write a number of different languages of Middle-Earth, such as:
Quenya, Qenya or High-Elven, the most prominent language of the Amanya branch of the Elvish language family. Tolkien compiled the "Qenya Lexicon", his first list of Elvish words, in 1915 at the age of 23 and continued to refine the language throughout his life. It is based mainly on Finnish, but also partly on Greek and partly on Latin.
Sindarin, the language of the Grey-elves or Sindar. Tolkien based Sindarin on Welsh and originally called it gnomish.
Sylvan, Westron, etc
Tengwar can also be used to write English, Welsh, Scottish Gaelic, Swedish, Polish, Esperanto [another invented language] and a variety of other languages."
As with ancient latin, when a word that is not found in the original texts is required, one can use the original grammatical rules to create new "modernized" words. I'm not saying that I did so, as I said, I'm not a linguist, but barring actually researching the original Qenya Lexicon, I have to go with what I can find. Is there a reason you believe "Councilof Elrond" to be more accurate than "TheGreyCompany"? I would very much like to know why.
Finally, I am definitely interested in your perspective, but please refrain from referring to other writers's styles negatively in my review section. It is neither informative, nor helpful.
