#4: Valyrian

Wondering where your dragons suddenly went? You might want to break out in Valyrian and say Skoriot ñuhyz zaldrizesse ilzi?

Valyrian, the language spoken in Essos, the eastern continent in the Game of Thrones world, was created by linguist David Peterson for the HBO series.

Game of Thrones isn't the first show to create languages for its characters. In fact, conlangs (or constructed languages) are relatively common in fantasy and science fiction. J.R.R. Tolkien was a notorious conlanger who created a number of languages for his fantasy world of Middle Earth, and conlangers have fleshed out Klingon and Romulan from the Star Trek series.
