They didn't often need it, as Kryten had studied almost every language or dialect known to man, for example Kryten was able to talk the language of the Kinitawowi GELFs. ("Emohawk") They were also able to understand the backwards English language of htraE through Kryten reversing it. ("Backwards")

("Entangled")
