The Voynich Manuscript: A Verbose Cipher Over an Isolating Language

Version 3.0 Update: This new version completely replaces the previous 2.0 release. It introduces the O2 Shannon Entropy measurement (Verbose Cipher theory), the Zipf's Law distortion curve, and completely refactored Python scripts for absolute reproducibility. Abstract: The Voynich Manuscript is one of the most enigmatic medieval artifacts, written in an unknown script and in a language that has so far resisted all phonetic translation attempts. Previous studies based on information theory have indicated that the text is not a random sequence. Building on this finding, my study investigates the structural architecture of the signal: is the Voynich spontaneous narrative prose, or does it conceal a conditional logic? Through Machine Learning algorithms (Logistic Regression) and information theory metrics (Shannon Entropy O1/O2, Zipf's Law), I measured the syntactic impact of textual repetitions and character distributions. To validate the hypothesis of an intentional grammar, I used the stochastic generator Copy-Mutate as a control group (Null Hypothesis). Subjecting the text to falsification tests (Contextual Asymmetry, Positional Syntax Z-Score, Phonotactics), the data suggest a marked statistical divergence from the mechanical generator. The mathematical evidence (O2 Entropy crash to 50.89%) highlights the presence of long-range grammatical rules consistent with a strongly isolating morphology, masked by a structured Verbose Cipher.
