Is the Arabic language uniform throughout the Arab world?
Whereas all Arabs use MSA for the exchange of printed information, especially on formal occasions, Arabic dialects are predominantly used for oral communication. Arabic as a spoken language has thus become more flexible. Although all dialects may have descended from a single source (which is either Classical Arabic or another spoken variety of it), their development was not tied to the norms or rules of Classical Arabic. However, in spite of the differences between all Arabic dialects, their underlying structures are quite similar.
