bacon thanks for the compliment
As I haven't slept for more than 24 hrs I will try
to be coherent but can't promise much. I cannot also not give you any information regarding the books we inquired about I am afraid.
However, and judging solely by the two examples you gave on Question 3, I'd say he follows the pattern most of my school books did/do. In other words, he lists the other tenses only if there's an irregularity to them. If you can form the other tenses -as in the case of Î±Î³Î¹Î¬Î¶Ï‰- by following the rules then he doesn't.
about question 4. all verbs ending in -Î±Ï‰ -ÎµÏ‰ -Î¿Ï‰ contract the vowel. I guess the book takes that as a given knowledge for some reason.
Question 5 I think I am too tired and dizzy to understand but maybe things won't get any better after I sleep (I can be extremely stupid at times)
Question 6, ÎµÏ…Î³Î³ÎµÎ»Î¯Î¶Ï‰ is a later 'creation' meaning exactly the same as 'ÎµÏ…Î±Î³Î³ÎµÎ»Î¯Î¶Î¿Î¼Î±Î¹'. It's one of these 'go figure' situations I guess, since you may find both used at the same period of time.
Question 7 I would reply if I knew what ark, or its Hebrew equivalent really means but since to my mind it means ÎºÎ¹Î²Ï‰Ï„ÏŒÏ‚ which of course originally meant "wooden box" I can't help you:)
Question 8. While the two can be used in the same context at times, Î±Î³Î½Î¿ÏŽ basically means 'being ignorant' so there is a slight difference between that and Î¿Ï… Î³Î¹Î³Î½ÏŽÏƒÎºÏ‰.
Not much help, I know, but I hope I answered some of your questions (till someone makes a better job of it)
