re: Silmarillian
You may find this site interesting, Johannes.... Tolkein, a linguist, used Finnish as a basis for much of his "invented" languages.
Quenya is a constructed language created by Professor J. R. R. Tolkien. It is the language of the High Elves in Arda, Tolkien's "secondary world" in which his novels such as The Lord of the Rings are set. Tolkien created numerous languages that were a part of his fictional world, but only the two Elvish ones, Quenya and Sindarin, ever became more or less completed.

According to its creator, Quenya's main models were Latin, Finnish and Greek. It could perhaps be said that Finnish was the most important of these in the beginning, because it gave Tolkien the initial impulse to create Quenya. Finnish influence does indeed seem strong in the earliest forms of the language, at least in vocabulary, where many words are Finnish in style. Later on the language distanced a little farther from Finnish, but the similarity never disappeared.
