Fathes Steve is right, there IS a term that describes the phonological process of consonants changing places within a word (due to whichever reason). It would apply to his example of "anominity". Unfortunately, as fate would have it, I have so completely forgotten it that no amount of cogitation has sufficed to bring it back.
I do, however, vaguely remember the example that illustrated the definition. It was about the Spanish word "murciélago", meaning "bat". Apparently, it evolved from a Latin word or expression that had two lexical components, "mur" (from "mus/muris", meaning "mouse") and something like "*caecalus/*caegalus" (from "caecus", meaning "blind"). Throughout the long period of of linguistic change, the "g" and the "l" got switched around, giving us the word "murciélago", which we use now.
I would absolutely love someone coming up with the name for this phenomenon. I shall keep on trying to remember anyway...
