Whether or not you are a fan of Game of Thrones or A Song of Ice and Fire, you’ve probably heard the word “Dothraki” before. If not, “Dothraki” refers to a fictional people and language from the popular book and TV series. Dothraki started out as a few words in the book series written by George R.R. Martin and became a whole language that was created by a man named David J. Peterson. You can even buy a language guide, created by Peterson himself, that comes with an audio CD to help with pronunciation.

Peterson is a linguist and conlanger, which is a person that makes conlangs (constructed languages). He has studied many of the world's languages and has a bachelor's degree in both English and linguistics, along with a master's in linguistics. He has not only created Dothraki, but also the other languages that are spoken on Game of Thrones, such as High Valyrian and all other variations of Valyrian. Anytime you hear someone speaking a language other than English on Game of Thrones, you are hearing a language created by Peterson.

Game of Thrones isn't the only media that Peterson has created a language for. He made four languages for Syfy’s Defiance. Defiance is a show that had three seasons about aliens that came to Earth searching for a new planet to make their home. Since there are many species of aliens on this show, all of whom already had a long history with each other before coming to Earth, they needed their own languages to help immerse the audience in this world.

For Defiance, Peterson created Kastithanu, L'Irathi, Indojisnen, and Kinuk'aaz. All four of these languages are quite different and have their own writing systems. Only the first three were featured in the first two seasons, with Kinuk'aaz being added for the plot of the third season.

Peterson has also made languages for other shows, as well as movies and a book, including The CW’s The 100, Marvel’s Thor: The Dark World, and Nina Post's Zaanics Deceit. I recently attended his lecture at Georgia Southern University where he spoke about his process of creating each of these languages, with a healthy sprinkling of pictures of his cat. His lecture was both funny and informative. When he was done speaking, he was happy to answer any audience questions from "Were you inspired by Tolkien?" to "What's the funniest thing your cat has done?" After the lecture, he was great about interacting with fans, taking photos and signing copies of his book.

In addition to the Dothraki language guide, Peterson has also written a book titled The Art of Language Invention in which he goes into great detail about his process and how he became a conlanger. If you still have questions after reading his book, he's happy to answer questions on social media, particularly tumblr where many people ask him for translations of different words and phrases in his languages.
