Any chance for nomenclator?

[Anton]

One step further would be to look at the vocabularies of Currier A vs Currier B and on the intersection of those. Because if two groups of people work on two documents, they well might have two different nomenclators. Or they might start with a common "base" nomenclator and then fill it up, as appropriate, with new words absent from the base nomenclator.

Quote from voynich.nu:

In general, words tend to either occur in both languages or they occur in 'B' only. There is a very short list of moderate-frequency words that occur only in language A.
