Could incantations explain some of the problems of the Voynich Manuscript

[nablator]

Three words with the same first three letters.
Three words with the same root.
Three words that swap letters around the same root.
Accumulation of duplicates
Lines that use several word types in a row 
...and others

The devil is in the details. You could be noticing these lines and not noticing others that are just as "wired". Do you mean weird?
