Some letters aren't letters

[Emma May Smith]

Indeed, and this is also used in other writing systems.

The point I tried to make is that these labels in clm 337 are all one, two or three characters long.
A verbose encoding of these would result in a lower entropy and longer words, and the Voynich MS labels could in theory be such an encoding.

Since there are (I believe) fewer than 13,824 different words in the MS, and 13,824 is 24 * 24 * 24, every Voynich word can in principle be represented by a triplet of Greek characters. Or Latin, of course.
Only a small subset of these also represent a valid number. (Leaving aside the point of the three 'lost' letters).

I'm open to the possibility that the Voynich text is written in a code. I find it a much better solution than a cipher, to be truthful.
