The oddities of the bigram "ed" pt. 3 : It's not just "ed"

[ReneZ]

For instance, according to my seven-slot ("crust-mantle-core") word model, the digraph ed can occur only when one of the "e-bench" elements E = {  {Che}  {She}  {ee}  {eee} } or one of the "e-gallows" F = {  {ke}  {te}  {CKhe}  {CThe} } is followed by a {d} element.  That already "explains" why ed is never word-initial. That model also predicts that, in a worth that has a gallows, ed cannot appear before the gallows. 

While I don't disagree, I think that it works in the opposite direction. The observation that ed (in fact e) does not appear at the start of words suggests that e is something attached to the preceding character. 

Clear example: in chol the ch can be detached and ol is also frequent. However, in chedy the ch cannot be detached. che can.

But we notice this from bigram (and trigram) statistics so these are useful.
Word statistics are also useful, but we do not know that Voynich word represent plain text words (even though this is something that people tend to assume), and word statistics are much more affected by spelling and spacing uncertainties.
