A key to understand the VMS

[nickpelling]

I find absolutely no problem with both q and y being straightforward characters which represent phonemes. The characters f p m can be linked to other characters and have strong positional rules, suggestive of being variants.

The notion that f and p are just orthographic variants of the double -leg gallows isn't supported by the data. They occur in different character contexts, with different frequencies, and often in different positions within words.

The notion that line-final m is an orthographic variant of r is only weakly supported by the data. Why do we see am dominate om there, when or is so frequent elsewhere?

If you have to shore up orthography with secondary explanations to make it work for something as basic as the letters of the Voynichese alphabet, it's not a very good starting point. :-(
