The location of <aiin> and <ain> groups

[Torsten]

<aiin> and <ain> appear word-initial over 500 times but are never once line-initial.

There is much more you can say about line initial words [see You are not allowed to view links. Register or Login to view.]:

Some elements are typical for a specific position within a line. For instance, 62% of the occurrences of the 'm'-glyph are at the end of a line. 

The first word of a paragraph is usually highlighted by an additional gallow glyph ('k', 't', 'p', 'f') as the first sign. This is the case in 617 out of 716 paragraphs (86%). Within a paragraph the words at the beginning of a line frequently start with a glyph 'y', 'o', 'd' or 's'. This occurs more frequently at the beginning of a line (68%) than this happens within a line (50%). The word 'daiin' occurs line initial 158 times, the word 'saiin' 59 times, the word 'dain' 49 and the word 'sain' 36 times.

Therefore the average length of the first words within a line increases. Moreover the second word is shorter than the first word in 48% of the lines and longer in only 32%.  Statistically, the second word in a line occurs twice as often as a subgroup of the first word (2.6%) than this is the case for any other words in a given line (1.3%). 

This observations can be explained as an unintended side effect of the autocopying method. The source for the first word in each line could only be found within the previous lines. Since the first and the last word in each line are easy to spot, the most obvious way is to pick them as a source for the generation of a word at the beginning or at the end of a line.  For the second word it is also possible to select the first word as a source. Since the first word in a line usually has a prefix the simplest change is to remove this prefix.

Within a cipher the paragraph and line initial glyphs could be stand for markers of some kind.

For the assumption of a natural language it would be indeed hard to explain that the text responds to the page he is written on.
