1. The most spectacular is the Table 4, displaying very strong dependency between the final of the previous word and the initial of the next word.
It means "fonetically dependency" - that the next word changes itself
dependent of a precious word.
The fonetical dependency is very often in arabic: for example the initial particle "AL" changes itself depending on a final of the previous word:
RAHMANU+AL+RAHIM --> RAHMAN-UR-RAHIM
2. As it is clear from the tables 1 and 3, the forms words very often reproduce
the same form (the same initial or the same final) in the next word. For
example, -aiin or qo- or -dy can repeat many times with good dencity.
It can mean (1) poetical text or (2) repeating the same morfology
