Gallifreyan (language)

By the Doctor's time, the archaic High Gallifreyan language spoken in the days of Rassilon had given way to a more contemporary form of the language, simply referred to as Gallifreyan. This vulgate is presumably the Doctor's native language.

Two forms of written Gallifreyan have been seen:
 * A vaguely Arabic-looking script, in a letter written by the Doctor to warn the High Council of impending danger. (DW:The Deadly Assassin)
 * This writing system is probably more appropriate for everyday communications, such as letters.


 * A complex system of interlocking circles. This writing system is used by the TARDIS' output screens, and is the one seen in the notes that the Doctor scatters around the TARDIS console room.
 * This writing system may be a specialized system optimized for communicating time-related concepts or TARDIS settings.
