Return of the Sycorax

Found on the Gallifrey One Doctor Who fan site

On the next page, in the You Ask Us feature, a reader poses the questions
was Sycoraxic based on a real language, was it backwards words, were there
hidden messages, was it a real, functioning language such as Klingon, or
were the actors making up gibberish? Russell T Davies, who scripted the
Sycorax word for word, answers: "Sycoraxic was completely invented. I just
made it up! But I did try to give it some logic, so that the same word
always meant the same thing: 'Soo chack chiff!' means 'You're going to
die!', which tends to get said a lot in Doctor Who. And I did try to parse
the verbs, but it wasn't too rigorous - I don't think universities will be
offering degrees in Sycoraxic any time soon!" It is accompanied by a
picture of the Sycorax leader, with the caption VOICE OF DOOM "Soo chack
chiff" yourself .
