The Arabic language is spoken in more than 20 countries, from Egypt to Morocco and throughout the Arabian peninsula. Modern Standard Arabic (MSA) is the official language throughout the Arab world, and its written form is relatively consistent across national boundaries. MSA is used in official documents, in educational settings, and for communication between Arabs of different nationalities. However, the spoken forms of Arabic vary widely, and each Arab country has its own dialect. Dialects are spoken in most informal settings, such as at home, with friends, or while shopping. Of all the spoken dialects, Egyptian Arabic is the most widely understood, due primarily to Egypt's role as the major producer of movies and TV programs in the Arab world.
