I am going to recommend You are not allowed to view links. Register or Login to view. and the rest of the site for a good starting point, and you'll see it encompasses the EVA-a/o alteration you see here. It would certainly be a mistake to treat that summary as the end-all-be-all, and I have found Emma Mae Smith's (do I have that name right?) blog to be very insightful; You are not allowed to view links. Register or Login to view., and went on to develop a theory of word structure from it. I'm omitting a great many people---surely  someone must have a good list of places with substantial Voynich analysis that is up to date?
