Ix
Ix is the childhood nickname of Ford Prefect, since his name in the native language of his father, who was from Betelgeuse 7, was unpronounceable in the language of his adopted home planet, Betelgeuse 5. In English, Ix translates to "boy who is not able satisfactorily to explain what a hrung is, nor why it should choose to collapse on Betelgeuse Seven".
