The Art of Inventing Languages

How does one go about inventing a language? David J. Peterson is the creator of the Dothraki and Valyrian languages for fantasy series Game of Thrones, as well as many others. He joins Michael Rosen for a playful discussion about all things conlang, and Michael tries his luck at inventing a new language for bacteria. Produced by Eliza Lomas for BBC Audio in Bristol.
