I just read through some of the previous threads on Modern Standard and Classical Arabic and found some excellent information about the differences among spoken dialects. But still I wonder, when is Modern Standard Arabic used? On television or radio? What kind of programs? Between Arabic speakers of different dialects? If I go to Alexandria or Amman, for instance, and start speaking my learner's version of MSA, will people respond to me in standard Arabic? Shukran jazeelan.
