Reference a definition which supports your position.
Good luck...
Again, I'm not disagreeing with your definition. I'm disagreeing with how you are applying it.
So...
You don't know how to use an Arabic index, do you brother....rotflol...
All the possibilities which we posited are contained not only in Wright's Grammar, but in Omar's and Lane's....so take your pick...don't get stuck on one page and ignore the rest...
You simply have no more excuses...
First, you only cited one page in the grammar. The page you cited is about negation, but you are saying the use here is affirmative. So why cite it? Second, Omar and Lane are lexicons, not grammars. You have cited zero grammatical references supporting your interpretation of ma here. None. The one page you cite is about negation. You simply cite a definition, which talks about various usages of ma (including negation) and then assume a particular one. Yet while you admit that ma here is governing the verb, you fail to point to any grammatical construction in which ma governs the verb as a demonstrative (as you translate it).
