Can VM be written in vowelless Latin?

[MarcoP]

Clearly the translation method is to look up meanings in the dictionary, ignore the grammar, and produce something that could make sense. This expedient is necessary because the Latin text is neither grammatical nor does it make sense.

....

none of the "Latin" texts in the paper have prepositions, which is a problem.

Many thanks to Stephen for going into the details of this passage!
What he writes of course applies to all Voynich "translations" so far. Since grammar is the weakest point in all proposals, I believe that the most efficient way to evaluate a solution is checking this aspect. Solvers utlimately deliver grammatical English, but is the grammar structure in the original Voynichese passage?

The conjunction is a trivial example: when a translation includes "and" does a corresponding word appear in the "word salad" generated by mapping Voynichese into words of the source language? Typically, word lists like "cat dog" are translated as "the cat and the dog", but this can only be legitimate if the proposed language had no conjunction.
As Stephen wrote, a similar argument can be made for prepositions: if prepositions appear in the English translation but are missing in the word-to-word mapping, the translation likely is the product of the solver's fantasy.
