David Peterson is a maker of languages. He makes new ways for people to talk. These are called constructed languages. He uses them for movies and shows. This helps the stories feel real.

Peterson became famous for his work on Game of Thrones. He made the Dothraki language for that show. He also made High Valyrian. He even made a language for giants. This language was called Mege Nuk. It was only used for one line of talk.

He works on many big films. For the movie Dune, he made the Chakobsa language. He also made a sign language for that film. He also made a writing system for it. This writing system is called an abugida. An abugida is a way to write using symbols.

Peterson loves to teach others. He wrote a book called The Art of Language Invention. He also made a free course on Duolingo. This course helps people learn High Valyrian. He often works with his wife, Jessie Peterson. Together, they make many new languages for stories.

David Joshua Peterson is a talented American language creator. He builds brand new ways for people to speak. These are called constructed languages. He uses these languages to make stories feel much more real. When characters in a movie speak a unique tongue, it helps the world feel alive. Peterson has become very famous for this special skill. He makes sure every new language fits the world it belongs to.

Making a language is a very big job. It is not just about making up new words. Peterson also creates ways to write them down. He often makes unique alphabets or special systems. For example, he created an abugida for the Chakobsa language. An abugida is a specific way of writing using symbols. He even makes sign languages for characters to use. This careful work helps tell a deep story. Every sound and symbol has a purpose in his craft.

Peterson's journey into this work started at a university. He studied English and linguistics at UC Berkeley. He also earned a master's degree in linguistics. In the year 2000, he attended an Esperanto class. This was his first time seeing a constructed language. Later, he helped start the Language Creation Society. He even served as its president for three years. These steps helped him become a professional creator.

He became a star through the show Game of Thrones. In 2009, HBO held a contest for a new language. Peterson won and created the Dothraki language. He also made High Valyrian for the same series. He even made a tiny language called Mege Nuk for giants. His work continues in big films like Dune. For Dune, he created the Chakobsa language and its sign language. He even made a language for the film Superman.

Peterson loves to share his amazing knowledge with others. He wrote a book called The Art of Language Invention. He also made a free course on the Duolingo app. This course lets people learn how to speak High Valyrian. Much of his recent work is done with his wife, Jessie Peterson. They work together to build worlds through speech. It is a wonderful way to connect art with science. His work brings magic to the screens we watch.

David Joshua Peterson is a prominent American conlanger, or language creator. Conlanging is the practice of designing fictional languages for use in art, literature, or film. Peterson uses his expertise to build immersive worlds through speech and writing systems. His work helps make fictional cultures feel authentic and historically grounded. He has become one of the most recognized figures in this specialized field. By creating unique tongues, he provides a layer of realism to massive entertainment franchises.

The mechanism of language construction involves much more than inventing random words. Peterson must develop complex systems of grammar, phonology, and syntax. He often designs unique writing systems to accompany the spoken word. These can take several forms, such as an abugida, which is a writing system where consonant-vowel sequences are written as a unit. He also creates abjads, which focus on consonants, and syllabaries, which use symbols for syllables. Some projects even require the invention of entirely new sign languages for non-verbal communication.

Peterson's work often involves creating different varieties of a single language family. For the television series Game of Thrones, he developed High Valyrian (Valyrio Udrir), a prestigious literary language. He also created its descendants, such as Astapori Valyrian and Meereenese Valyrian. This mimics how real-world languages evolve over time through geographic separation. He even created a tiny language called Mag Nuk, or "great tongue," used for a single line of dialogue. This level of detail ensures that the linguistic history of a world feels deep and continuous.

His professional journey began with formal academic training in linguistics. He earned BA degrees in English and linguistics from the University of California, Berkeley. He later received an MA in linguistics from the University of California, San Diego. His interest in constructed languages was sparked in 2000 during an Esperanto class. In 2007, he co-founded the Language Creation Society with nine other creators. He served as the president of this society from 2011 to 2014. These experiences transitioned him from a student to a leading professional in the field.

The significance of his career is reflected in his massive portfolio of media projects. In 2009, he won a contest held by HBO to create the Dothraki language for Game of Thrones. Since then, he has worked on major films like Dune (2021) and Dune: Part Two (2024). For the Dune films, he created the Chakobsa language and its corresponding sign language. He has also contributed to franchises like The Witcher, Shadow and Bone, and Star-Crossed. His ability to meet the demands of high-budget productions makes him a vital asset to modern storytelling.

Peterson's technical versatility is shown through his diverse linguistic creations. In the series Defiance, he created several languages, including Castithan, which uses the Fajizwalino abugida. For the show The 100, he developed Trigedasleng, a language derived from a cryptolect based on American English. In the film Bright, he invented Övüsi, an Elvish tongue that utilizes an abugida. He even worked on the language of the witches in Motherland: Fort Salem, a project he completed with his wife, Jessie Peterson. Each project requires a different set of rules and cultural contexts.

Beyond entertainment, Peterson is dedicated to teaching the art of language invention. He wrote a book titled The Art of Language Invention in 2015. He also produced a documentary film called Conlanging: The Art of Crafting Tongues in 2017. To make his work accessible to the public, he created a free High Valyrian course on the Duolingo app. This course was expanded in 2022 to coincide with the premiere of House of the Dragon. Through these efforts, he connects the scientific study of linguistics with the creative world of art.
