My name is David Peterson, and I'm a language creator and writer. I'm the author of Living Language Dothraki, The Art of Language Invention, and Create Your Own Secret Language. I've been creating languages for television shows and movies since 2009. Some of the productions I've worked on (and languages I've created for them) are: HBO's Game of Thrones (Dothraki, High Valyrian, Astapori Valyrian); Syfy's Defiance (Castithan, Irathient, Indojisnen, Kinuk'aaz); Freeform's Motherland: Fort Salem (Méníshè); Netflix's The Witcher (Hen Linge); the CW's The 100 (Trigedasleng); HBO's House of the Dragon (High Valyrian); and Legendary's Dune (Chakobsa).
