Calgary engineer believes he's cracked the mysterious Voynich Manuscript

[Aga Tentakulus]

Is there any researcher who can show similar repetitions of words (such as quadruplets or quintuplets) in any other language's manuscript?

You cannot do this in any language other than Turkish.

Ja, ohne Ende.
Beispiele in deutsch.
"Wenn hinter fliegen fliegen fliegen, fliegen fliegen fliegen nach"
Wenn hinter robben robben robben, robben robben robben nach"

Und jetzt mit Tonverschiebung.

"Wenn hinter Griechen Griechen kriechen, kriechen Griechen Griechen nach."

Kinderreime machen es möglich.

Yes, without end.
Examples in German.
"When behind fly fly fly fly fly fly fly after"
When behind robben robben robben, robben robben robben"

And now with a shift in tone.

"When Greeks crawl behind Greeks, Greeks crawl after Greeks."

Nursery rhymes make it possible.
