Lingo is a show that’s about our relationship with language, how it goes beyond communication, and the impact it has on our lives, cultures, and traditions. This week, we find out what it takes to create a fictional language for a show. We talk about the language of the horselords in Game of Thrones, Dothraki. David J Peterson has also created languages for shows like The 100, Thor: The Dark World, and Syfy's Defiance.
