I noticed long ago that English has some neologisms that come in pairs of Latin and Greek. Their current meaning in English may or may not be the same, but they translate literally as the same. For example:

metathesis=transposition
metamorphosis=transformation
metaphor=transfer

What I'm wondering, while I should be working instead, is what would be the Latin partner for metastasis? I don't mean a Latin-derived word that refers to the migration of cancer cells, as metastasis specifically does. Rather, I'm looking for a Latin-derived English neologism that means change of place. Metathesis doesn't seem to be it. And while we're at it, what is the Greek-derived partner for transubstantiation? If there is one?
