The "Arabic language" enjoys many strengths, but it has not been sufficient for it, or not exploited properly. Colloquial dialects have cruelly encroached upon the Arabic language itself.
Some colloquial spoken dialects can express and overcome many of the problems of the classical language, especially the Egyptian dialect. In Egypt there is no single colloquary dialect, let alone all Arab countries, which means that the spread of colloquical dialects and their excessive adoption will lead to confusion.
