In the Voynich Manuscript, where a word sits in its line changes how it is spelled

In six of ten spelling pairs, the variant the scribe chose depends on where the word falls in its line. No cipher key we tested behaves this way, and neither does Latin.

Many Voynich words come in pairs that differ by one or two letters, like chedy and shedy. If the text were a simple cipher, the choice between them should be random, or follow the meaning. It doesn't.

We looked at ten of these pairs and checked which variant appears at each position in the line. In six of them, the choice depends on position, with z-scores between 3.9 and 9.2.

What we compared it with

We ran the same test on Latin texts of the same genres, and on 216 versions of a fifteenth-century cipher key. None of them showed the effect. A scribe copying from a key has no reason to care where on the line a word lands.

That points away from a simple cipher and toward a writing system with its own rules for layout, which is what the leading answer to “What kind of text is it?” already suggests.

Supports “-m is a line-final form of -in / -n” as the answer to Why do spellings change at the end of a line?
Evidence F-111
Counts against “A cipher of a known language” on What kind of text is it?
