The evolution of P/F vs T/K raises important questions

[cvetkakocj@rogers.com]

It's clear from the above charts P/F cannot simply be Ke or Te, as Ke/Te did not become popular until pharma. 

Did anybody noticed that most Voynich glyphs look like Latin letters, except EVA q, t, k, p, f. On the other hand, Latin   t, k, f, p cannot be found in the Voynich Manuscript. From this we can assume that EVA t and k might stand for Latin t and k. If these letters are followed by a short vowel, the vowel is not written, because it is pronounced as swa. It was Dr. Bax who suggested that the Voynich Manuscript is written in semi-abjad, because of the reduced vowels.
