I’m happy to announce that Marco Ponzi and I have recently had a paper published in Cryptologia titled “Glyph combinations across word breaks in the Voynich manuscript”.
The text of the Voynich manuscript exhibits relationships between neighboring words that have not formally been explored. The last and first glyphs of adjacent words show some dependency, and certain glyph combinations are more or less likely to occur. The patterns of preferences for glyph combinations demonstrate the existence of higher-level glyph groups. The behavior of the glyph combinations may arise due to changes in a glyph caused by its neighbor.
A preprint of the paper is available to download: Glyph Combinations across Word Breaks in the Voynich Manuscript – Preprint
