A key to understand the VMS

[Davidsch]

Torsten I wrote it many times before:  I think you need comparative languages and large corpora of them. 
But I see no other comparative languages in your research.
Perhaps a piece of text that has been formed around a specific theme by a specialist, for example on plants.

I think you are all confused by these graphs: it does not show anything conclusive.
It only shows that some words are more in other sections than others.
