TUTORIAL: How to write in Elvish. This is the most detailed and thorough I've seen. Also, check out a lovely book called "The Languages of Tolkien's Middle Earth". It explains elvish (Sindarian and Quenya), Dwarvish, and others. Written by Ruth S.
song lyrics are sung by Billy Boyd, acting as Pippin, in 'The Lord of the Rings: The Return of the King,' and the movie stills, are from 'The Hobbit: The Battle Of Five Armies.' My favorite part of the movie.
