A Structural Model of Voynich Manuscript Token Construction: Investigating Prefixes, Modifiers, Family Blocks, and Generative Word Formation

Core Focus: This research note investigates two remaining exceptions from the prefix-pathway generalization sweep: the e+ky root family and the i-vowel -ain/-aiin/-aiiin family. Key Findings: The analysis demonstrates that the two exceptions operate via completely unrelated mechanisms. e+ky represents a hard categorical block driven by gallows-gallows dissimilation ($k/t$ letter clashes), rendering layered prefixes impossible. Conversely, the -ain family displays a genuine, graded dose-response shift where the layered pathway collapses rather than the direct one, while the prefix d- remains flat across all three vowel-run lengths. Methodological Significance: Rather than contradicting the core e-class findings, separating a hard phonotactic block (eky) from a graded dose-response (-ain) clarifies the boundaries of the manuscript's prefix-selection rules and confirms that gallows-adjacency imposes independent structural constraints.
