Middle Earth/Sindarin

Sindarin is one of the languages spoken by the Elves? in J. R. R. Tolkien's work. Its phonology and some of its grammar are based on Welsh; most of its vocabulary is original, save a few words designed to pun with English.

It is the language of the Sindar?, the elves who remained in Beleriand? and waited for Thingol?, when he had disappeared.

The language was described briefly in an appendix, and probably in more detail in other works. Some people claim to be able to read and write this language, so perhaps it has joined Esperanto and Klingon as a real-world artificial language.

Quenya, the language of the High Elves (particularly the Noldor) was designed to sound like Finnish, and the two were made as if they evolved from a common ancestor. But Sindarin reflects different aesthetics.
