I've got a question on the Arabic text as well. In section 3.5, writing, áyn and ghayn both have different forms "at the end" of a word (the part that just says beginning - middle - end). However, in the word itself, when the letter is at the end, it looks completely different than the "beginning-middle-end" end part.
Ayn: In the end ـع مدفع Madfa3 Cannon
yet you also have, in another box right below,
In the end ع مدفع Madfa3 = Cannon
as you can see, those isolated "end" example letters are completely different. Which one is correct?
In the beg غ then you have its example word غزال and you see that the "in the beg" sample does not correspond to the beginning form in the word. Please help!
(if this isn't clear just go to section 3.5 in Writing)
