David J. Peterson

David J. Peterson is a member of the Language Creation Society which specialises in the creation of constructed languages, or 'conlangs', from scratch. Peterson has worked in this field since 2000.

On 12 April 2010 HBO confirmed that Peterson was fleshing out the language of the Dothraki culture into a fully-fledged conlang for use in the series, with a vocabulary of over a thousand words. It is possible that the other languages from the later books might receive similar treatment as the series continues.
