Kossian Gallifreyan(Circular script:) is a variant speech of the original Doctor Who language Gallifreyan. The dialect is spoken in the Kossian province of Gallifrey, where it is protected as regional language. Kossian Gallifreyan is an attempt to build further the fictional language, based on the findings of the language in the show.
Kossian Gallifreyan is written either in a circular script, used by the Circular Gallifreyan language, or the Latin alphabet, although less used. This is due to the great Latinisation of Koss.
