The oddities of the bigram "ed"

[ReneZ]

In general, it is very hard to explain how the Voynich text can be gibberish, due to its many consistencies throughout the MS. As a consequence, it cannot be used to 'easily' explain anything.
In this particular case, the use of 'ed' is not an on/off from two different hands, but there are intermediate stages (small as they are), and these are in yet another hand.

The emergence (or disappearance - less likely) of 'ed' looks like an evolution which is independent of the meaningful vs. meaningless question.
