Quenya

Quenya, a constructed language, was created by Tolkien.

I don't speak Quenya.

You translate from Quenya to Klingon? Awesome.

Quenya is an Eldarin language.

Artificial languages are invented languages. Some examples are Esperanto, Lojban, Interlingua, Klingon, Toki Pona, Lingua Franca Nova, Vling, Afrihili, Na'vi, Kotava, Solresol, Quenya, Lingwa de Planeta, Fremen, Galach, Pandunia and Novial.

If the idea of “exotic” and complex languages with features you’ve never imagined thrills you, I guarantee you’ll get more out of studying Navajo, American Sign Language, Kikuyu, Vietnamese, Cree, Cantonese, Quechua, or Nuuchahnnulth than Quenya, Klingon, or attempting to make your own.
