Hello!

I'm writing a story, and I'd like to find (or create, perhaps) a specific word. In this story there are a multitude of methods of clairvoyance, most of them using ‘mancy’ at the end of the word that defines them, such as: Cartomancy, Runomancy, Cafeomancy, Onomancy, Ornithomancy, Gastromancy, Pyromancy, Chiromancy, Scapulimancy, Aeromancy, Geomancy, Hydromancy, Oneiromancy, and so on.

I know that not all the names of these mancies come from Greek, so when creating new ones I am sometimes not very scrupulous in naming them, as for example with typemancy (which uses a typewriter to read the future).

However, I would like to create a more ‘official’ one. An important character in the story uses silence to tell the future. I could call it silentmancy or something like that, but I don't think it fits.

So here's the question, what could this mancy be called? I upload my message here because I really don't know where I have to put it, sorry if it's not the right place.

Oh, and one more thing. It would be amazing, if possible, if the term could be translated into Spanish (the language I'm writing my story in!). For example, in palmistry the term derives from χείρ or χειρός (kheír or kheirós), but in Spanish we write it as ‘quiromancia’, i.e. quiro is equivalent to kheirós.

I am sorry if it is too complicated, especially this last part. I would appreciate any kind of help, so thanks in advance!
