Repetition of letter groups

[ThomasCoon]

Did I overlook something, or could you have done with one less "group of four"?

I think this could be done by making the first purple one the start.
Any word starting left of it could be shifted right by one group.

You're right Rene. That would make the table more concise. That is a good observation.

The main idea of the image is that this 4-unit structure may be the lowest-common-denominator that repeats throughout the manuscript (sometimes all 4 components are present, sometimes 3 or 2, sometimes only 1).

I could be completely wrong. But if I'm right, I can see a cipher application. For example: 

to encode "a" = Group 1 sign + Group 2 sign + Group 3 sign + NO Group 4 sign
to encode "b" = Group 1 sign + Group 2 sign + NO Group 3 sign + Group 4 sign
to encode "c" = Group 1 sign + NO Group 2 sign + Group 3 sign + Group 4 sign
etc.

One thing to consider is the "unique" vords as compared to those that repeat at least a few times.

Unique vords don't necessarily follow the [exact] same structure.

Note that unique vords can often be broken into two vords that do follow patterns similar to the vords around them, just as removing EVA-P from the beginning of paragraphs (treating them as a special case) often yields vords that follow regular patterns.

Also, something I've noticed is that EVA-ch -sh (which you've classified in the "c" group) are more positionally flexible than many of the others and MIGHT belong in a class of their own (or differ in some other way).

That's a very good point JKP - I wonder if ch belongs to its own class, or if "ch" and "e" clusters are different. I only grouped them together on the basis that they look alike (which may be a bad reason)
