Theory:Doctor Who audio discontinuity and plot holes/False Gods


 * Jane is famillar with the word TARDIS, instead of the proper Gallifreyan name for time machines (T.T Machines, which simpily means Time Machine). Perhaps she learnt the word TARDIS from one of the Doctor's relatives.
 * This old chestnut again? It's long been established that other Time Lords, including those that never leave Gallifrey, do know the acronym TARDIS.  The issue here is how other Time Lords could have known the acronym when Susan claimed to invent it in An Unearthly Child.  One obscure solutions comes from ST: The Exiles, which intimates that the Doctor, prior to leaving Gallifrey, was involved in the engineering of TARDISes.  It's quite possible that Susan could have introduced him to her acronym, and then he could have spread it to the wider engineering community.  However, that's really going the long way round for a very simple explanation.  The answer is actually in An Unearthly Child.  Susan never says she invented the phrase "Time and Relative Dimension in Space".  What she says, quite specifically, is that she "made up the name from the initials".  Thus, it is, properly, called a "Time and Relative Dimension in Space" on Gallifrey.  Susan just shortened it into an acronym.  Clearly, anyone else could do that, too.
