Today I will speak with you... without a written paper, or a written speech. (N)or even speak to you in the Classical (fuṣħā) Arabic language. Today I will speak with you in Libyan dialect, and address you directly, as an individual member of this Libyan people. And I will speak extempore. Even the ideas and the points are not prepared in advance. Because this is a speech from the heart and the mind.
Now the explicit association between dialect, extempore speech, and speaking as "one of us" is fairly obvious, if interesting. But the odd thing is that this paragraph, like the rest of the speech, isn't very dialectal at all; it seems far closer to Standard Arabic than to any dialect. Some dialectal features are present, but a lot of unambiguously Classical constructions are used; even something as basic as the first person singular oscillates between Libyan n- and Classical 'a-. What it looks more like is some sort of intermediate ground between dialect and standard - or, if you prefer, like the highest level of Arabic that he is capable of extemporising in at short notice.
Readers may recall that Ben Ali tried the same gambit in his last speech (though Mubarak never resorted to it.) An omen? Let's hope so.
