What does That Character say in That Scene of the Movie?
You can sonsult a well-informed unofficial site that has the movie quotes translated with word-by-word analysis and sound clips of every sentence: http://www.elvish.org/gwaith/movie.htm You must have in mind though, that the Elvish of the movie is not genuine Elvish. Some of those words and rules had to be reconstructed by rules also used by Tolkien (explained in a question below) so that they won’t contradict known evidence. If you study this Movie Elvish, you must have in mind that this is by no means canonical, and future evidence might consist these reconstructions wrong. David Salo, the linguist who composed the Elvish lines of the movie, has told in the Elfling list, that he will prepare a site about it.
