Has anyone ever "deciphered" a paragraph?

[MarcoP]

I was just thinking that it would require a great amount of creativity to convert any paragraph of Voynichese into something (anything) that makes sense using any repeatable method. This alone would be quite the feat, and I don't think it is possible.

In my opinion, a repeatable method that generates something that makes sense would be THE solution. Of course this has not been found yet, it could be possible that it will be found in the future, who knows?

For the method to be repeatable, it should be possible to express it as a set of rules for someone else to reach the same results. This means, and this is the most important condition, that the method may not include an "interpretative step" which basically turns it into a one-way cipher. 

Some levels of language rules are quite simple, I am thinking in particular of grammatical rules. E.g. the fact that subject and verb must agree in number. Even more basically, the fact that words belong to different part-of-speech categories and that the order in which words appear next to each other depends on grammar rules. Sadly, grammar is widely overlooked by would-be solvers: they tend to generate word-salads in their target language and jump from word-salads to perfectly grammatical English. But their target language has a grammar itself, though they choose to ignore it.

Also, Voynichese has a lot of structure, e.g. word morphology, repeating words, consecutive similar words, line-effects, paragraph effects, correlation between the last character of a word and the first character of the following word, differences between paragraph-text and labels, the different "dialects" in the different sections.... These phenomena must be explained, for instance they could be an effect of the structure of the underlying language or an effect of the writing system. These features are our best hope to understand more of Voynichese, but, again, they are largely ignored by would-be solvers.

I agree that repeatability is based on rules. Languages have rules and Voynichese has structures that could well be the result of some unidentified rule-systems. In my opinion, only translation attempts that are solidly grounded in both these sides of the problem have some hope to result in something that can be repeated.
