In The Magic Grandfather, by Jay Williams (published 1979), there are several spells that do certain things. For instance, Aldoragamba luro vopo vir voarchadumia is a transportation spell. Tripsarecopsem helps with the crystal ball.
Near the beginning of the notebook of spells he found a description of how to pronounce the hard words, which was a great help. He fixed each step for himself so that he was clear about how to open the portal and keep it open. Above all, he set himself to learning the transportation spell by heart. It had only five words, but they were a mouthful: Aldoragamba luro vopo vir voarchadumia.
This, said the notebook, was a ball made out of rock crystal, whatever that was. Looking into it and saying the word Tripsarecopsem, you could see any person or thing at a distance and this helped you concentrate on them so that you could bring them to you.
Where did Jay Williams get these spells from? Did he make them up? Do they mean anything?
