The Arch-preposterous—p152 notes

Gornahoor / Mister


… the word ‘Gornahoor’ is used by the three-brained beings on the planet Saturn in courtesy; they utter it before the name of one whom they are addressing.


It is the same with your favorites on the planet Earth. They also have added to the name of every person the word ‘Mister’ …

Mister is derived from master, a man having authority over a place or others.
