Suggestions for decomposition of the Voynichese characters

[-JKP-]

I guess there are two different meanings for "positional" in terms of scribal abbreviations...

• For example, the -is, -em, and "tail" abbreviations are usually at the ends of words because they don't have to attach to additional letters, and because they lend themselves to faster writing in those positions. There is a pattern to the positions.
  
• But there is also a positional requirement for some abbreviations (like y). When positioned at the beginning or the end, they mean different things. The y abbreviation usually means "us" or "um" at the ends of words but one would never use it for "us" at the beginning of the word. At the beginning it has to be "con" or "cum" (or something similar).
  

These abbreviations were flexible, but there still had to be some order for them to be readable.
